中国石化非常规油气资源潜力及勘探进展

中国石油化工集团有限公司(简称中国石化)矿权区内拥有较为丰富的非常规油气资源,煤层气可勘探面积为10.19万km2,煤层埋深小于2 000 m的煤层气地质资源量为11.02万亿m3。页岩气可供勘探面积为17.5万km2,初步估算页岩气地质资源量为15.9万亿m3。页岩油勘探面积为11.76万km2,具有较大的资源基础及潜力。中国石化自2004年开始关注非常规油气资源,先后启动了页岩油气、煤层气等非常规油气资源的研究和勘探工作。目前在泌阳凹陷页岩油勘探泌页HF-1水平井分段压裂后获日产油23.6 m3;元坝地区多口陆相钻井测试获得高产气流,建南地区建页HF-1井日产气12 300 m3;延川南区块煤层气已探明地质储量为106.47亿m3,多口井排采获工业气流,初步形成了中国石化非常规油气资源多类型、多阶段的勘探开发格局。

The potential and exploring progress of unconventional hydrocarbon resources in SINOPEC

The unconventional hydrocarbon resources are very abundant within the registered blocks of SINOPEC(China Petroleum & Chemical Corporation).The potential exploration area for coalbed methane(CBM) reaches 101.9 thousand km2 and the resource with the buried depth smaller than 2 000 m is 11.02 trillion m3.The potential exploration area for shell gas is 175 thousand km2 and the volume is 15.9 trillion m3.The potential exploration area for shell oil reaches 117.6 thousand km2 and the resource is huge.Since 2004,SINOPEC has started to pay attention to unconventional hydrocarbon resources and launched research and exploration on CBM,shale gas and shale oil,etc.Recently,unconventional hydrocarbon resources exploration of SINOPEC has obtained breakthrough and progress.By the horizontal well fracturing section,Biye HF-1 obtains 23.6 m 3 / d commercial shell oil flow in Biyang Depression.By testing,several continental wells get high-yield commercial shell gas flow in Yuanba Block,and Jianye HF-1 obtains 12 300 m 3 / d commercial shell gas flow in Jiannan Block.The CBM proved reservoir in Yanchuan south block has reached 10 647 millon m 3,and lots of wells get commercial CBM gas flow,which makes the pattern of "various resources type"and "multi-stage"exploration and development form on unconventional hydrocarbon resources in SINOPEC.
