储层成岩产物对于油气运移的指示意义——以塔里木盆地群苦恰克构造带东河塘组为例
The significance of diagenetic products for petroleum migration in reservoir:An example from Devonian Donghetang Formation in Qunkuqiake structure zone, Tarim Basin
摘要
Abstract
The Donghetang Formation is the important exploratory formation in the Qunkuqiake structure zone,Tarim Basin. But no agreement is yet achieved as to the direction of migration and accumulation of petroleum in the reservoir. The dolomite and ankerite cements are extensive in the sandstones. The dolomite cement developed in the sandstones during early diagenetic stage and their content in the sandstones increase respectively from east to west. The formation sequence of ankerite cement was later than that of petroleum migration in the reservoir. They replaced the previous dolomite cement during middle diagenetic stage and their content in the sandstones increase respectively from west to east that is contrary to that of dolomite cement. Ankerite cement is thought as an indicative mineral for the strong reduction environment in sandstone. The accumulation of ankerite cement in sandstones reveals the rules of migration and accumulation of petroleum in reservoir. The result of the study provides new evidences for the westward direction of petroleum migration in the reservoir.关键词
