英买2~3构造侏罗系至志留系测井储层评价

为了对塔里木盆地英买2~3构造侏罗系至志留系的测井储层与油气资源进行研究和评价,描述了该构造上侏罗系至志留系各地层的基本电性特征;进行了构造上及周边井重要层系地层的构造倾角和古水流研究。通过岩心物性分析和油气描述,结合地层对比和地层倾角资料的研究,结果表明:英买2~3井区侏罗系地层从北西向南东逐渐抬升;横向上,古水流方向是南东东—北西西,物性特征是北西往南东逐渐变好,标识物源方向与古水流方向一致;纵向上,底部物性较中上部好,说明了沉积时底部较中上部水动力强的特点;英买3井油气显示好于其它各井,可望在英买3井南部高点地区获得新的油气显示。

EVALUATION OF RESERVOIR LOGGING FOR YINGMAI STRUCTURE NO.2~3OF JURASSIC TO SILURIAN

AbstractIn order to evaluate the oil and gas resources of the structure from Jurassic to Silurian system in Yingmai structure No.2-3 in Tarim Basin, basic electric properties of all strata from Jurassic to Silurian system in the structures are investigated. Core analysis and paleocurrent of important in the wells both in and around the structures are investigation, shows that Jurassic strata in Yingmai structure No.2-3 rise up gradually from northwest reservoir improved from northern west to southern east, and the direction of deposit source accorded with that of paleocurrent. Vertically, properties of formation on the bottom is stronger than that on middle and top. The oil and gas display in Yingmai well 3 is better than n other wells. Therefore, new oil and gas display is to be found from the apex area, which is the southern part of Yingmai well 3.
