二连盆地巴音都兰凹陷油气勘探再获新发现

New Finding of Hydrocarbon Exploration Was Obtained in Bayindulan Sag, Erlian Basin

2001年,二连盆地的隐蔽油藏勘探取得了重大突破,在巴音都兰凹陷的巴Ⅱ号、巴Ⅰ号构造整装探明、控制了两个千万吨级的油藏。借鉴2001年成功的经验,2002年科研人员通过精细基础地质研究,深化成藏条件分析,在巴7西断鼻的油气勘探再获新发现,控制了千万吨级的巴38油藏。本文详述了这一发现的研究思路、内容及油藏发现、评价的过程。

A breakthrough for subtle reservoir exploration in Erlian Basin was obtained in 2001. Two ten-million-ton grade oil reservoirs were proved and controlled wholly in Ba-Ⅱ and Ba-Ⅰ structures, Bayindulan Sag. Based on the successful experience in 2001, new discover of hydrocarbon exploration was obtained in the west fault nose of Ba-7 structure through the fine basic geological research and deep analysis for reservoir-forming conditions, so a ten-million-ton grade oil reservoir of Ba-38 was controlled in 2002. The research train of thought, content and the reservoir finding, evaluation process are described in this paper.
