摘要
"十二五"期间,中国石化油气勘探取得重大突破,其中地震勘探技术、超深井钻完井技术、水平井分段压裂技术及测井录井技术的创新发展起到了关键支撑作用。对未来油气勘探中存在的寻找石油储量战略接替困难、新增储量品位下降、埋藏深度增加、复杂勘探对象对工程技术的要求越来越高等技术难题进行了详细分析,认为中国石化油气勘探发展方向主要集中在陆相隐蔽油气藏、海相油气藏、致密碎屑岩油气藏、山前带油气藏、火成岩油气藏、海域及非常规油气资源等7大领域,并分析了7个领域面临的主要技术挑战,指出了物探技术、井筒技术及测井录井技术的主要攻关方向。
During the 12th"Five-Year Plan",great breakthroughs in oil and gas exploration were made in Sinopec and technological innovative developments in seismic exploration,ultra-deep well drilling and completion,horizontal well staged fracturing,mud logging and well logging provided crucial support.Nevertheless,some technical challenges will be encountered in oil and gas exploration in the future.For example,it is hard to find new oil reserves for strategic replacement,the quality of new reserves is degraded,and burial depths increase while the geological complexity of exploration targets requires a higher engineering technical requirement.Sinopec has committed to oil and gas exploration that will mainly target seven kind of reserves including continental subtle reservoirs,marine reservoirs,tight clastic reservoirs,piedmont reservoirs,igneous reservoirs,sea and unconventional oil and gas resources(shale gas).This paper presents a analysis of the main technical challenges in these seven types of reservoirs and identifies the major technical research directions in geophysical exploration,borehole stability,mud logging and well logging.
