摘要

白音查干凹陷有近20 年的勘探历史,一直没有重大发现,在全面分析已有钻井成败的基础上,运用新的理论方法,对该凹陷形成演化以及地层构造进行了深入研究,充分认识到不整合对油气运移、聚集以及对原有油藏的破坏,选准了目的层;三维地震解释,充分考虑到上下地层“二元结构”对构造的影响,解释方案有了大的变化,通过一系列新认识指导勘探,钻井成功率大大提高,2003 年探明石油储量602 ×10⁴ t ,为今后的勘探提供了成功经验。

Abstract

Nearly 20 years ’ exploration has been done for

Baiyinchagan depression but with no significant discovery.

By comprehensive analysis on drilled wells and using new

theory , further research has been done on depression

evolution and stratigraphic structures. Strata : fully

understand effect on petroleum migration ,accumulation and

original reservoir by unconformity and then select target

zone ; 3D seismic interpretation : fully consider effect on

structures by“binary structures”overlying and underlying ;

interpretation plan also changed greatly. After further

understanding for guiding , drilling succeeded greatly with

proved OIP 602 ×10⁴ t ,which provides experience for future

exploration.
