摘要
南海西部 4 个盆地典型井的岩心测试资料表明:在受泥质含量控制的碎屑岩发育区(非受钙质影响区),铝钒元素含量较低,对应的砂岩孔隙度、渗透率相对较好,寻找低铝低钒元素含量区,对应的储层相对较好,反之储层较差.本文利用该原理对南海西部莺歌海盆地LT区域的储层进行识别和划分,结合铝钒元素含量将储层划分为有利储层带、过渡带、欠储层带,对有利储层进行更加准确的识别.
Abstract
The core testing data of typical wells in four basins in the western South China Sea show that in areas where clastic rocks are developed and controlled by mud content(not affected by calcium),the aluminum vanadium element content is low,and the corresponding sandstone porosity and permeability are relatively good.Searching for areas with low alu-minum and vanadium element content corresponds to relatively good reservoirs,while con-versely,reservoirs are poor.This article uses this principle to identify and divide the reser-voirs in the LT area of the Yinggehai Basin in the western South China Sea.Based on the a-luminum vanadium element content,the reservoirs are divided into reservoir zones,transition zones,and under reservoir zones,in order to more accurately identify favorable reservoirs.
