Strengthen Seismic Technological Application; Improve Exploration and Development Efficiency Liu Zhenwu, Sa Liming and Dong Shitai 2015, 34(1): 1-8.  Abstract ( )   PDF (9213KB) ( )   As a dominant technology for oil and gas exploration and development, geophysical technology plays an important part in oil and gas exploration and development. With oil and gas exploration continually unfolding, the areas of oil and gas abundance have been basically covered with 2D and 3D seismic survey lines. However, the 3D coverage rate of the royalty blocks remains low. The 3D coverage rate is less than 22 percent for the eight main onshore basins. With the seismic processing and interpretation technological development, the acquisition data acquired in the past are unable to meet the need for pre-stack depth domain processing and pre-stack reservoir prediction owing to the limitations of technology and equipment. It is necessary to strengthen the strategic seismic study of the replaceable and potential areas under the background of focusing exploration efforts on low-permeability, deep-layer, offshore and non-conventional areas. The healthy development of oil and gas exploration and development calls for more efforts for seismic coverage study and application of seismic technology in the initial stage. Based on the analysis of the current issues existing in application of seismic technology, this paper comes up with the suggestions to strengthen seismic coverage study, increase the investment for initial strategic study and beef up processing of the targets in old data.

Field Test of Managed Pressure Drilling Technology and Equipment Sun Haifang, Xie Zhengkai, Li Jie, Zhou Yingchao, Song Zhoucheng and Feng Jinghai 2015, 34(1): 14-17.  Abstract ( )   PDF (3260KB) ( )   Precise managed pressure drilling (MPD) technology is a key technology to ensure the safe drilling in narrow safety density window formations and pressure-sensitive formations. The technology and equipment are mature abroad, but the service price is rather high. The prototype research was completed during the nation’s 11th Five-Year Plan Period, but the prototype was not brought under field test nor put into industrialized application. To push on its localization and industrialization, so as to solve similar drilling problems in strategic oil/gas fields in Tarim, Sichuan and Chongqing, China National Petroleum Corporation has set up a project for field test of precise MPD technology and equipment. Through top-design of “4511” targets, reasonable effective project organization, strengthened nodal control, and strict process monitoring, the complete set of MPD technology and equipment is configured, a stride from the engineering prototype to commercial application of MPD is realized, and a fast lane for the conversion of MPD innovation into production forces is built. This MPD technology and equipment has been widely used in Sichuan and Chongqing, Jidong, Tarim and overseas blocks to support the petroleum exploration and development, resulted in remarkable economic efficiencies. It has embodied CNPC innovation capacity, hoisted CNPC engineering technology to a new level and enhanced CNPC competitiveness at overseas markets.

Gas Well Operations--- Advances in Field Tests Yang Lingrui, Xie Zhengkai, Han Liexiang, Qiao Kangni and Ma Faming 2015, 34(1): 18-21.  Abstract ( )   PDF (3101KB) ( )   Snubbing operation is a new bright spot of downhole operation technology newly developed in recent years. It’s an edge tool to raise single-well production. To accelerate the upgrading of gas-well snubbing technology and equipment in order to accommodate E & D demands and trend, China National Petroleum Corporation focused the breakthrough point on field tests of gas-well subbing technology and equipment. To ensure the tests scientific and safe, innovations were continually made, superior resources centralized, and integrated management adopted. Just upon the opportunity of shale gas development in Sichuan-Chongqing area, 60 snubbing jobs have been tried on gas wells, including pipe stripping, hot-tapping and milling. And another 13 snubbing jobs were test-proved in well workover operations. All those jobs have guaranteed the effective development of unconventional tight-gas or shale-gas resources. Remarkable results have been achieved. The annual production is increased by 14400×104m3, a direct economical benefit of 200 million RMB created, the snubbing technology & equipment upgraded, and the snubbing operation largely improved.

Pipelines Enterprises to Base Technological Creation on International Strategic Coopreation Zhao Choumin, Kang Liping, Wang Yuqin, Li Li and Zhang Huifen 2015, 34(1): 28-35.  Abstract ( )   PDF (5680KB) ( )   With economic globalization accelerated, the enterprises of oil and gas transmission pipelines face great pressures from market competition, technological upgrading as well as safety and environmental protection. To keep the enterprise in safe and stable operation and sustainable development of the leading technologies, PetroChina Pipelines Company (CPP) is focused on the core elements of technology, management and talents on the basis of independent research and development of key technologies. The company has also made joint efforts with foreign famous research institutions and enterprises for launching projects, paying mutual visits at high levels, combined training, technology and management benchmarking, taking advantage of technological development resources both inside and outside the sector for a variety of technological creation activities. The company has learnt from latest international pipelines technology and management patterns, actively involved itself in formulation and revision of international criteria, taken part in international academic (technological) association, launched China International Pipelines Conference, engaged itself in international exchange and cooperation for technological research and managerial improvement. The company provided support for integration, import and re-creation of foreign technology while focusing on settlement of key bottlenecks that restrict safe, high-efficiency and environmental-friendly operation of pipelines. As a result, the company has apparently improved its capability for technological creation and cultivated a number of pipeline technological experts with international visions, increasing its international influences.

Latest Development of Marine Braodband Seismic Acquisition Technology Yu Benshan and Sun Naida 2015, 34(1): 41-45.  Abstract ( )   PDF (3470KB) ( )   Marine broadband seismic acquisition technology not only improves the pre-salt and pre-basalt geological imaging precision but also raises the imaging quality of difficult-to-identify reservoirs, such as thin layers, subtle traps and special lithologic bodies, thus effectively improving interpretation precision of seismic data and lowering the risks for exploration. The strong market demand has stimulated development of marine broadband seismic acquisition technology in recent years. A number of acquisition methods appeared abroad, such as slant streamers, over-under streamers, hydrophone-vertical geophone (dual sensor) streamers and multi-component towed streamers. However, the domestic research is still in its preliminary stage in this area. This paper is focused on the fundamental principles of the above-stated technologies, aiming to offer references for the related study at home.
