Abstract:

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.

Key words: hydrocarbon resources, effective source rock, exploration acreage, petroliferous basin, frontier in the west
