摘要

塔里木盆地东部的奥陶系、寒武系、震旦系发育碳酸盐岩,累计厚度最大超过2 000m,是油气赋存的主要载体,近5年来天然气勘探不断有发现。根据地质层位与岩相差异,将塔东碳酸盐岩储层划分为奥陶系台地石灰岩、奥陶系台地白云岩、寒武系台缘丘滩体、寒武系斜坡重力流沉积及震旦系白云岩等5大类。通过10余口主要探井的岩心、薄片、实验及测录井等资料分析,认为奥陶系台地石灰岩可局部发育缝洞优质储层,奥陶系台地白云岩储集条件整体优于石灰岩,寒武系台缘丘滩体储层叠加厚度大,寒武系斜坡可发育储集性能良好、厚度较大的重力流沉积储层,震旦系白云岩中也发现了有效储层。顺南地区奥陶系石灰岩、古城地区白云岩分别已获工业气流,2个地区可相互借鉴勘探经验以扩大场面。古城寒武系台缘丘滩体领域的新探井已钻遇气层,是今后几年解剖的重点。罗西斜坡寒武系重力流沉积储层较发育,并有低产气流。经地震相分析和储层预测,古城东斜坡也发育重力流沉积沉积储层,具有较大的勘探价值。震旦系白云岩发育差异大,需要继续寻找有利岩溶储层分布区。

Abstract

Carbonate rocks have been developed in Ordovician,Cambrian,and Sinian of Eastern Tarim Basin,and the cumulative maximum thickness exceeded 2000 meters.They are the main carrier of oil and gas,and a great deal of natural gas have been found in the past five years.Based on geological horizons,lithofacies,and reservoir differences,carbonate natural gas exploration domains of Eastern Tarim Basin can be classified into five types:carbonate platform limestone of Ordovician,carbonate platform dolomite of Ordovician,bioherms-shoal flats of platform margin in Cambrian,carbonate gravity flow of Cambrian slope,Sinian dolomite.Carbonate reservoir characteristics of all areas are synthetically analyzed through drilling core,thin section,experiments and logging data of over 10 drilling wells.It is held that good fracture and cave reservoir in carbonate platform limestone of Ordovician can partly distributed.Carbonate platform dolomite of Ordovician is better than limestone.Bioherms-shoal flats of platform margin in Cambrian have large Stacking thickness.Good quality and large thickness of carbonate gravity flow can be found in Cambrian slope.And effective reservoir also was found in Sinian dolomite.Commercial Gas has been found in limestone and dolomite of Ordovician in Shunnan-Gucheng area.Hence,the two regions can learn from each other's experience of exploration to expand the scene.
