Title
STUDY ON RESERVOIRS OF THE JIAMUHE FORMATION IN 5TH DISTRICT,KARAMY OILFIELD
摘要
克拉玛依油田五区佳木河组储层,包括了火山岩、沉积岩和变质岩三大岩类,具裂缝-孔隙双重介质。本文用“火山机构”进行了相区划分,从宏观和微观结构研究了储层特征和储集性能,确定出储层下限并对高产区进行了预测。
Abstract
Reservoirs of the Jiamuhe Formation in 5th district,Karamay Oilfield,consist of igneous,sedimentary and metamorphic rocks with crevice-poredual medium.According to identification of facies based on volcanic me-chanism and the study of the speciality and behaviours of the reservoirs frommacrostructure and microstructure,the reservoirs can be divided into threegrades in the present paper.It is showed that the crevices play a dominantrole in improving the physical property of the reservoirs and increasing theyield of oil wells.
