中国石油“十二五”物探技术研发应用进展及启示

Geophysical Technologies Developed and Applied by Petro China during the 12^(th) Five-Year Plan

中国石油集团"十二五"期间应对油气勘探开发逐渐向复杂构造、低渗透、深层碳酸盐岩、致密油气等复杂领域拓展的局面,分盆地、分领域制定了一系列物探技术政策、强化物探技术应用的做法和启示,主要包括:优化资料采集技术,强化野外过程管理和质量监督;狠抓基础工作,加强资料处理解释,充分挖掘资料潜力,努力提升物探成果质量与效果;对制约生产发展的关键瓶颈技术开展专题技术攻关,以推动复杂高陡构造、低渗透、碳酸盐岩缝洞储层、致密油气等复杂目标的勘探;围绕四大领域关键地质问题,强化技术集成与配套,推广成熟技术,努力提升油气勘探开发保障能力;积极储备前沿技术,准确把握技术发展趋势,开展单点高密度、宽频可控震源、三分量地震、井中地震、时频电磁技术现场试验等,为"十二五"石油、天然气年探明储量持续保持在6×108t和4000×108m3以上奠定了技术基础。

Oil and gas exploration and development of PetroChina Company Limited is gradually focused on expansion ofcomplicated fields during the 12th Five-Year Plan Period, such as complicated structure, low permeability, deep-layer carbonaterock and compact oil and gas. A series of geophysical technological policies has been formulated on the basis of division of basinsand fields, enhancing the application methods of geophysical technology. Those methods include optimizing data acquisitiontechnology to enhance field process management and quality control, focusing more efforts on the basic work to enhance dataprocessing and interpretation and fully tap the potential of data for higher quality and performance of geophysical results, andlaunching research projects on the technological bottlenecks restricting development of production to promote exploration ofcomplicated targets, such as complicated high and steep structures, low permeability, carbonate rock fractural and cavity reservoirs,and compact oil and gas. The efforts are also focused on the key geological issues of four main areas to strengthen technologicalintegration, spread mature technologies and improve the logistic capability for oil and gas development. Meanwhile, PetroChinais engaged in preparation of frontier technologies and pays close attention to technological development trend while making fieldexperiments on single-spot high-density, wide frequency controllable vibrator, three-component seismic surveys, borehole seismicsurveys, and time-frequency electromagnetic technology, laying a technological foundation for the targets to keep the annualproven reserves of oil and natural gas at 6×108t and 4000×108m2 during the 12th Five-Year Plan Period.
