| 摘 要： | 从沉积环境入手,依据岩芯、铸体薄片、测井解释、压汞试验、物性分析等资料,并结合区域地质背景对塔里木盆地北部轮南地区石炭统卡拉沙依组砂泥岩段S3砂组进行了研究。结果表明:该区砂泥岩段S3砂组优质储层的岩性为岩屑砂岩、含砾不等粒砂岩、粉砂岩等;储层孔隙类型以粒间孔、粒间溶孔为主,发育少量粒缘缝;碳酸盐岩胶结物在轮南地区砂泥岩段S3砂组储层中较为普遍;钙质体积分数较高。钙质主要以方解石、铁方解石、铁白云石胶结物的形式存在;优质储层的分布受控于沉积环境,集中发育在砂泥岩段S3砂组上部的三角洲前缘相的分流河道与前缘席状砂和砂泥岩段S3砂组下部潮坪相的潮道和砂坪微相里,所以这些区域是油气勘探的重点目标区。

| Abstract: | Based on core,cast thin section,log interpretation,mercury penetration and physical property analysis,S3 sand layer of Carboniferous sand and claystone member in Lunnan area of north Tarim is analyzed according to regional geological setting and depositional environment.The result shows that the lithology of high quality reservoirs in S3 sand layer are lithic sandstone,pebbled sandstone,siltstone and so on;the types of pore space are mostly intergranular pore and intergranular dissolved pore,and little grai... |
