多方法识别和预测盐下生物礁

摘要
巴格德雷区块位于卡拉库姆盆地二级构造单元查尔朱台阶的中南部地区,如今该区的油气发现主要集中在上侏罗统下部的卡洛夫—牛津统礁灰岩中,上覆盖层为上侏罗统上部的启莫里组大套的盐膏层。本文采用钻井、地质和地震等多学科资料,利用沉积环境分析、地质建模、地震相分析和地震属性提取等手段,综合识别、预测盐下生物礁,搞清生物礁的剖面形态和平面分布特征,从中总结出开展盐下生物礁识别的几种有效的手段和方法。
The Bagdelay block is located in the middle-south of the Chareju area in a tectonic zone of Armu basin. So far most oil and gas reservoirs which have been discovered are in the reefs in Carlorf-Oxford formation of upper Jurassic, sealed by very thick salt or gypsum in Qimoly formation of upper Jurassic. In this paper drilling data, geological data and seismic data and several analysis methods, such as sedimentary environment analysis method, geological modeling method, seismic facies analysis method, seismic attribute extraction method and other methods, were used to synthetically analyze and predict sub-salt reefs in the area, the profile feature and plane distribution characteristics of the reefs were identified, and the effective methods and means to predict reefs in this area were summarized and become available.
