综合配套的勘探工程技术研究
|
摘要
我国既要在地表条件极其恶劣、地下构造极其复杂的新区寻找新油气资源 ,也要在老油区滚动勘探增加新储量 ,因此不仅要选好选准勘探领域 ,更重要的是充分发掘和综合应用先进而适用的勘探技术。未来 5～ 1 0年中国石油天然气股份有限公司油气勘探有五大重点领域 (大面积低丰度岩性油气藏 ,复合型隐蔽油气藏 ,前陆盆地陡带复合构造油气藏 ,台盆稳定区碳酸盐岩缝洞油气藏与台盆断陷区潜山油气藏 ,老油区复杂断块油气藏挖潜 ) ,针对各领域地质特点 ,分析了对勘探工程技术 (地震采集技术 ,地震处理技术 ,地震综合解释技术 ,地震储集层描述技术 ,测井技术 ,钻井完井技术 ,压裂酸化技术 )的需求。五大重点领域的油气勘探目标具有 4个共同特点 (隐蔽性 ,复杂性 ,目标识别难 ,资源品位差 ) ,确定不同领域的勘探工程技术对策时 ,要强调针对性、适用有效性和合理配套性 ,还要强调创新性。介绍了勘探工程技术综合应用的 6个成功实例。油气勘探发展依托于勘探工程技术的进步 ,今后要努力提高单项勘探工程技术水平 ,大力发展综合勘探技术。参 2
China is looking for new oil and gas resources in new area with harsh surface conditions, extremely complex subsurface structures, as well as new reserves in maturing fields by progressive exploration. The selection of the exploration targets is important, at the same time, the fully development and comprehensive utilization of advanced and applicable exploration technologies are even more important. In the coming five to ten years, oil and gas exploration of PetroChina will focus on the five key types of target (lithological reservoirs with large area but low petroleum abundance, composite subtle reservoirs, composite structural reservoirs on steep slopes in foreland basins, fractured and cavernous carbonate reservoirs in stabilized area of platform basin, buried hill reservoirs in down faulted area of platform basin, and complex faulted block reservoirs in the mature oil regions). Based on different geological characteristics of these targets, the analysis of the demands for exploration engineering technologies (seismic acquisition technology, seismic processing technology, comprehensive seismic interpretation technology, well logging technology, drilling and completion technology and fracturing and acidizing technology) is conducted. The common features of oil and gas exploration targets include: concealment, complexity, delineation difficulty and poor data quality, so whence matching the exploration engineering technologies stress must be laid on their accordance, applicable effectiveness, reasonable match as well as creativeness. 6 successful examples of comprehensive utilization of exploration technologies are introduced. The progress of oil and gas exploration depends on the advancement of exploration engineering technologies. The authors hold that in the future the advancement of every single exploration engineering technology and the progress of comprehensive exploration technologies should be given more attention to.
