Practice from Significant Experiment on Effective Development of Changqing Ultra-low Permeability Reservoirs Li Zhongxing, Li Songquan, Liao Guangzhi, Tian Changbing, Wang Zhengmao, Shi Cheng’en, Lei Zhengdong, Liu Weidong, Yang Haien 2021, 40(4): 1-11.  DOI: 10.3969/j.issn.1002-302x.2021.04.001 Abstract ( )   PDF (5222KB) ( )   The ultra-low permeability reservoir is characterized for wide coverage, tightness, fine pore throat and poor physical properties. It is difficult to put the reservoir of this kind under development. In 2005, PetroChina kicked off the experiment on ultra-low permeability (0.3mD) reservoir development at Changqing Oilfield. A total of five unique technological families were created in the experiment -- quick formation assessment, optimization of the effective flooding system, multi-stage fracturing renovation, surface optimization and simplification, and systematic low-cost drilling technology. The management model for the ultra-low permeability reservoir was also developed at the same time. As a result, the annual oil production was rapidly raised to 802×104t in 2014 from 31×104t in 2008 and kept stable at that level, effectively helping Changqing fulfill the objective of 5000×104t. With water-flooded development of the ultra-low permeability oil reservoirs (ultra-low permeability of III category in particular) being unfolded, some development contradictions gradually appeared, such as more difficult replacement, high water flooding and water channeling ratio, low production rate and low productivity. Changqing Oilfield conducted an important development experiment by changing water-injecting development mode in 2016. After four years of experiment, a series of EOR technologies was basically developed, which is an integration of supplementing energy in advance for ultra-low permeability reservoirs, increasing energy under pressure, storing energy in swallowing, and combining drive with filtration. The integrated technology solved the bottlenecks in using traditional water-flooding development mode -- ineffectiveness and low producing degree, thus raising production substantially. The field experiment indicated that the productivity was raised by 12 percentages. Currently, the integration of technologies comes under industrialized experiment and will become a powerful engine for Changqing Oilfield to “accelerate its development for the second time.”

Improving the Effectiveness of Shear-wave Seismic Exploration through Geophysical Technology Innovation Gou Liang, Zhang Shaohua, Li Xiangyang 2021, 40(4): 12-19.  DOI: 10.3969/j.issn.1002-302x.2021.04.002 Abstract ( )   PDF (4190KB) ( )   As hydrocarbon exploration shifts towards low permeability, deep subsurface, offshore and unconventional reservoirs, exploration targets become more and more complex, and finding oil and gas successfully becomes more and more difficult. Radical or disruptive innovations in geophysical technologies may be required to tackle these issues. Such innovations may only be possible by the use of shear-waves, and the combination of P- and shear-waves signals the onset of elastic wave exploration, making it possible to provide more geophysical parameters and search for oil and gas directly. Recently, BGP has tested this approach in Qinghai Sanhu. Through increased source tonnage, improved source coupling and a high-density and high-fold wide line geometry, high quality shear-wave data are obtained whose S/N ratio, frequency content and depth penetration are all comparable with P-wave’s. Consequently, a higher subsurface resolution, at least double, is achieved using shear-wave, as compared with P-wave data. Furthermore, two wells are drilled successfully based on the shear-wave data in Tuofeng Shan and Tainan area, yielding a high rate of daily gas production in both wells. These achievements have greatly advanced shear-wave as well as elastic wave seismic technologies, leading the race in geophysical innovation, and laying the foundation in maintaining BGP’s market share in global oil and gas exploration.

Innovative Thinking and Suggestions on HSE Supervision Model under Digital Transformation Yan Lunjiang, Mao Yaming, Li Jianying, Wang Shunyi 2021, 40(4): 20-24.  DOI: 10.3969/j.issn.1002-302x.2021.04.003 Abstract ( )   PDF (1821KB) ( )   Currently, digital technology is under rapid development and effectively integrated and used with the industry. How to use digital technology for establishment of the HSE management system is an important subject in the new era to make HSE management function as on the platform, under the network and as intelligent. China National Petroleum Corporation (CNPC) attached great importance to high-quality development and established the supervision and management system that is “under unified management and duty-bond at the various levels” with some achievements made in this area. However, the supervision and management system, generally speaking, still operated under the traditional model, while digitalization is in its preliminary stage. Therefore, the system is unable to satisfy the demand for full-process, all-weather and all-around collaborative supervision and management. CNPC will concentrate its efforts to push ahead with digital transformation, accelerate innovation and transformation of the HSE management model, and improve management efficiency and performance on the basis of optimizing and changing the management method. It is proposed to make top-level design for a unified HSE management model, depend on the achievements made in digital transformation and development to establish three new-type capabilities of HSE management (risk-sensing capability, intelligent risk-detecting capability and risk early-warning capability), construct the HSE management platform at all levels according to classifications, levels and joint actions and regulations, focus on implementation of digital management to promote establishment of the HSE remote online management mechanism, and coordinate the efforts for acceleration of the HSE management support system.

However, there are few methods for evaluation of the profits from management-innovating achievement or evaluation of management-innovating capacity, affecting implementation of management innovation. Therefore, it is necessary to profoundly analyzing the management-innovating system and performance mechanism of modern enterprises, standardize the spectrums of business management and production management factors for the oil and gas field companies, and establish the profit-sharing model of management-innovating achievements. The study has drawn the following conclusion. (1) Management innovation is an integrated complex system covering investment and production of the company’s development elements as well as the company’ research on soft sciences and application of the achievements. The performance-creating nature of management-innovating achievements is the value-added process brought about from innovation of the production elements portfolio. (2) Based on the principle that the profit is shared according to contributions from the management elements, the net profit value (the net present value and net profit) of management-innovating achievements is equal to the net profit value of the project multiplied by the profit-sharing rate of management-innovating achievements. (3) The profit-sharing rate of management-innovating achievements is closely related to the profit-sharing base coefficient of management elements, the progressive sharing base coefficient and the innovation intensity coefficient of management achievements. Confirmation of the results indicated that this evaluation method is simple and easy to operate. It can help modern oil and gas field enterprises use the management elements as an important production factor to share the company’s profit.

How to economically and effectively improve the bidding success rate holds the key to development of China’s overseas oil and gas business. This paper studies the bidding strategy and method for the new overseas oil and gas projects. The paper focuses on identification of the strategically-selected zones, the oil-enriched basins, and determination of the key nations and regions for business expansion. It also compares the different bidding mechanisms of various nations, analyzes the bidding parameters, optimizes the decision-making process, investigates and analyzes the market conditions and historical data, identifies the competition trends, and makes a multi-dimension analysis of the competitors and their bidding intentions. The bidding rules are taken into account to optimize the bidding strategy, define the scope for making the appropriate bidding decisions, and provide the scientific basis and references for the final bidding decisions. Take the 14th round of bidding in Brazil as the research target and application case. Based on the company’s own capacity and positioning for business development, the appropriate factors are determined to calculate the proper bidding scope on the basis of four dimensions – geological success rate, commercial success rate, scale of resources, and net present value of single barrel. Adoption of a stable and healthy bidding strategy can both ensure the bidding success rate to some extent and avoid the excessive competitive premium, providing the references for the company to make the decisions on investment in the overseas oil and gas exploration and development projects.
