2024, 43(4): 50-57. Abstract ( )   PDF (2813KB) ( )  
Focusing more efforts on reform of the internal allocation system of the enterprises is an important part of restructuring the State-owned enterprises and perfecting the modern corporate system. It is necessary to innovate the wage incentive system guided by work post value in consideration of the actual business management conditions, thus accelerating the company's high-quality development. Based on investigation and analysis of assessment on the Chinese and foreign work post value and development in the wage incentive theory and practice, this article takes a certain large-scale oil and gas field enterprise for example, analyzes the internal mechanism of wage incentive guided by work post value, constructs the wage incentive model and designs the wage incentive plan. The study indicates that (1) currently the wage of employees from the oil and gas enterprises does not link with market wage level, work post value, and the employees’ individual ability and business performance. It is necessary to create the methods and tools for carrying out wage incentive, both scientifically and reasonably. (2) The work post value should be divided into general labor and value creation. The value is defined by the duties of work post as well as examination and measurement of business performance and results. (3) The performance bonus should be determined jointly by the efficient of work post, examination of the individual's performance and the total amount of wage at the unit, instead of being linked with“ the personal information” like professional titles and positions. (4) Design of the wage incentive plan should be aimed at linking the employee’s wage with work post value and the total amount of performance bonus with work post value in the subsidiary’s total amount of wage. The designed incentive plan should be appraised, analyzed and confirmed for its rationality and feasibility. The conclusion indicates that construction of the work post value-guided wage incentive model is generally in line with the internal allocation law and the guidance of current management. The designed plan clearly links work post value with allocation of wage and reasonably enlarges the gaps in the wages of employees from the various units and various work posts. It is simple, easy-to-understand and operable, providing the reference basis and decision-making support for oil and gas enterprises to innovate the wage incentive mechanism.

2024, 43(4): 58-65. Abstract ( )   PDF (7637KB) ( )  
CCUS-EOR is an internationally-accepted way for reduction of carbon emission. CO2 oil-flooding technology is the main EOR technique for low-permeability oil reservoirs and widely used worldwide. The CCUR-EOR industrial chain is relatively mature abroad. The projects mainly adopted the miscible flooding process with the infrastructure of long-distance transmission pipelines and the help of the relative incentive policies. China is comparatively late for its CCUR-EOR industrial development and currently under the critical stage from on-the-field experiment to industrialization. As for indoor experiment, China has made an in-depth study of the CCUS/CCS mechanisms for continental reservoirs and developed a series of experimental technology. As for on-the-field experiment, the relative processes were developed in connection to oil flooding and anti-corrosion, injection and production as well as surface engineering. As for industrial development, the state has formulated the “1+N” to promote the CCUS/CCS industrial development. China should establish the theoretical and technological indexes system of the full CCUS/CCS industrial chain and accelerate research and development of the cost-effective capture technology of low-concentration CO2, the supercritical long-distance CO2 piped transmission technology, the technology able to improve CO2 EOR significantly and on a large scale, and the technology to keep the integrity of CO2 buried geological bodies on a long-term and large-scale basis.

2024, 43(4): 66-74. Abstract ( )   PDF (7543KB) ( )  
Study of geothermal energy from middle-to-deep layers aims at development of a certain renewable clean energy to reduce dependence of fossil fuels and carbon discharge. It is an important measure for green and low-carbon transition of the energy industry. Focusing on the bottlenecks in geothermal development of the middle-to-deep layers in the Jizhong zone, such as geological identification, development plans and surface engineering, this article makes study of the key underground and surface technologies, which leads to the following results. (1) The thermal reservoirs of the middle-to-deep layers in the Jizhong zone are mainly layered sandstone and block buried hill. The bottleneck for sandstone geothermal development is the difficulty to identify the sandstone layer with a relatively poor re-injection ability. The bottleneck for buried hill geothermal development is the strong heterogeneity of the thermal reservoir requiring high drilling success rate and high designing precision of the development plan. (2) Prediction of the favorable thermal reservoir and sweet spot identification technology are able to effectively identify the sweet spot of a thermal reservoir. Combination of optimized development parameters with dynamic analysis while drilling+production-injection experiment+ five sensitivity experiment brings about high-efficiency sandstone geothermal development. (3) Combined application of geophysical data, drilling log and testing data can precisely identify the position of the buried hill thermal reservoir. The high-efficiency gravity flow buried hill development technology leads to high production based on a few wells and full pressure-free re-injection in the same layer. (4) The technology of using geothermal high temperature differential pump for warming, anti-sewage and anti-scaling improves the geothermal heat-exchanging rate and reduces the operational and maintenance cost. (5) Using geothermal energy for warming, refrigeration and steam generation according to applications based on the different scenarios further expands the range of geothermal utilization and improves the utilization rate of geothermal resources, thus bringing the resource energy into full play.

Geothermal energy is an important renewable energy. It is also one of renewable energies focused in China's 14th Five-year Plan. China has topped the world in direct utilization of geothermal energy for many years. However, China is still left behind the advanced foreign countries in the area of development and utilization technology used in middle to deep layer geothermal fields.Currently, global geothermal startups are experiencing rapid growth with more efforts invested in development of geothermal resource. There is a variety of scenarios for geothermal energy utilization. With the installed capacity of geothermal power growing steadily, significant progress has been made in development and utilization technology. Concretely, the achievements have been reflected in four areas. (1) The design technology is gradually matured for the middle to deep layer closed heat exchange system. (2) A historic breakthrough is made in EGS technology, which has a great potential for utilization. (3) Many countries have attached importance to the role of aquifer thermal energy storage in making up the imbalance between energy supply and demand. They accelerated the study in the related areas, such as selection of the sites for aquifer thermal heat storage, heat recovery rate and risks analysis. (4) Re-injection has become a common practice for development of middle to deep layer aquifer geothermal fields. The latest technology of re-injection numerical simulation and well design, anti-corrosion, anti-scaling and anti-clogging has effectively extended the life cycle of geothermal fields. Under the background of “dual carbon” goal, China should regard the study of key technologies as the main breakthrough for development of new quality productive forces while rapidly modernizing the development and utilization technology of middle to deep layer geothermal fields and effectively improving the economic feasibility of geothermal projects, bringing about a sustainable growth in geothermal utilization.
