准噶尔盆地阜东斜坡区头屯河组岩石物理相特征
|
摘要
利用岩心、薄片、钻井、测井等资料,对准噶尔盆地阜东斜坡区头屯河组储集层沉积相、成岩相和压力相进行研究和识别,将储集层进行岩石物理相的划分,对储集层进行综合评价,进而预测有利储集层发育带。通过沉积相、成岩相和压力相的叠加和复合,总结出沉积相+成岩相+压力相的组合,共划分出15类岩石物理相。利用自然伽马、声波时差、密度、补偿中子及深感应电阻率测井曲线,结合Fisher典型判别建立各岩石物理相的定量判别函数,并对识别结果进行检验。以薄片鉴定为基础,以段为单位进行岩石物理相平面分布研究。结合试油资料,对头屯河组储集层进行综合评价分级,归结为四类储层,最终实现有利储集层预测。
Core,thin section,logging and drilling data were integrated to study and identify sedimentary facies,diagenetic facies and pressure facies of the reservoir rocks in the Toutunhe Formation of Fudong slope area,Junggar Basin. On this basis,we divided petrophysical facies,performed comprehensive evaluation of the reservoirs,and predicted favorable reservoir development areas. A total of 15 petrophysical facies were identified according to the sedimentary faices,diagenetic facies and pressure facies. Quantitative discriminant functions were built for each of the 15 types of petrophysical facies by using GR,acoustic,density,compensated neutron and deep resistivity logs,and in combination with Fisher typical discriminant,and the correctness of the identification result was tested. The petrophysical facies of the three members in this Formation were mapped based on thin section observation. The reservoirs in the Toutunhe Formation were comprehensively evaluated and classified into four types in combination with production test results,realizing prediction of favorable reservoirs of the Toutunhe Formation.
