Zhang Dajing, Liu Jinxia, Shao Zhibing, et al. Evaluation of oil/gas exploration potentials in SINOPEC's frontiers in West China[J]. 2005, 26(5): 605-612.DOI: 10.11743/ogg20050508.
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.
