塔里木盆地油气资源及勘探方向

Huang Difan,Zhao Mengjun, Zhang Shuichang. OIL AND GAS RESOURCE AND EXPLORATION TARGET IN TARIM BASIN.

近年来，塔里木盆地的生油研究取得很大进展，根据塔里木盆地烃源岩分布和成熟度研究的结果，作者主要讨论了以下几个问题：①塔里木盆地总资源量可能略低于以前的估算，并且减少的可能只是原油资源量；②塔里木是一个富含天然气的盆地，富气的根本原因是三套烃源岩中两套源岩在晚近期以生气为主；③烃源岩的分布和成熟度决定了台盆区的勘探重点是中、西部地区；④侏罗系源岩是塔里木盆地成为大气区的重要物质基础，应加强在北、西。

A mighty advance has been made in oilgeneration study in Tarim basin in recent years. Based on the distribution of source rock and maturity study, this paper mainly discussed following questions: total resource extent is slightly less than that estimated previously, and mainly in oil resource extent; natural gas is enriched in Tarim basin, because two of three sets of source rock mainly generated gas in late period; the distribution and maturity of source rock resulted in exploration target being in center and west part of Tarim basin; Jurassic source rock is the important basis for Tarim basin as a big gasproduction area, so we should strengthen oil and gas exploration dominated by Jurassic as source rock in northern, western and southern Tarim basin.
