摘要

摘要: 塔里木盆地巴楚地区下丘里塔格组主要为一套局限台地相沉积,广泛发育厚层状白云岩储层,是目前寒武系最为重要的油气勘探目的层.运用测井、地震资料,结合岩性组合特征综合分析,对巴楚地区下丘里塔格组进行了层序地层划分,确定出该组包含4个三级层序,层序内部主要表现为海侵体系域和高位体系域的组合.其中,高位体系域不完全发育.在层序分析的基础上,通过岩心薄片和钻井油、气、水显示资料综合分析,认为三级层序影响了巴楚地区下丘里塔格组白云岩储层发育,是储层发育的主要控制因素.下丘里塔格组(岩溶型)白云岩储层主要发育于层序界面下部的高位期,特别是有短期暴露界面下的高位晚期.

Abstract: The Upper Cambrian Xiaqiulitage Formation in Tarim Basin has widely developed thick dolomite on restricted platform,and has become the most important reservoir.According to the multidisciplinary analysis of the data on wells and seismic,the Upper Cambrian Xiaqiulitage Formation is divided into four sequence stratigraphic units in Bachu area.The sequence stratigraphic units were charactered by TST and HST.The HST does not develop completely.On the multidisciplinary analysis of lithologic character of dolomite and indication of oil and gas on wells,the sequence stratigraphic units have vital effect on dolomite reservoir.The karstic dolomite reservoir mainly developed in the HST of sequence stratigraphic,especially in the last period of HST with exposition.
