西部新勘探区油气资源勘探潜力评价

以有效烃源岩发育为主线,从生、运、聚、保等角度,综合分析了影响油气成藏的油源条件、油气输导体系、时空配置关系和保存条件等要素,将中国石化西部新勘探区的油气资源潜力分为4类。其中,Ⅰ类区块9个,Ⅱ类区块24个,Ⅲ类区块20个,Ⅳ类区块17个。塔里木盆地的塔中和准噶尔盆地的准中等9个Ⅰ类区块,是大中型油气田勘探的重点地区,应加紧勘探,并建议积极探索Ⅱ类区块、综合研究Ⅲ类区块、舍弃Ⅳ类区块。

Evaluation of oil/gas exploration potentials in SINOPEC's frontiers in West China

Several factors influencing hydrocarbon accumulation,including oil source conditions,hydrocarbon carrier system,time-space matching and preservation conditions,are comprehensively analyzed by taking the development of effective source rocks as the main subject to study and taking account of hydrocarbon generation,migration,accumulation and preservation.The exploration potentials of SINOPEC's frontiers in West China are classified into 4 types.There are altogether 9 type Ⅰ acreages,24 typeⅡ acreages,20 type Ⅲ acreages and 17 type Ⅳ acreages.9 acreages in Tazhong of Tarim basin and in Junzhong of Junggar basin are of type Ⅰ,and are the major exploration acreages for discovering large and medium oil and gas fields.The exploration in these acreages should be intensified.It is proposed to actively explore type Ⅱ acreages,comprehensively study type Ⅲ acreages and relinquish type Ⅳ acreages.
