摘要

求取裂缝性油藏裂缝孔隙度的方法通常是先通过成像测井识别和拾取出高导缝,然后再利用成像测井对常规测井识别的裂缝和计算的裂缝孔隙度进行标定。在缺少成像测井资料的情况下,以克拉玛依油田百31井区二叠系裂缝性油藏为实例,以全直径样品分析所获得的单点裂缝孔隙度为依据,以深、浅双侧向电阻率计算裂缝孔隙度为手段,在常规测井进行裂缝识别以及划分裂缝发育段的前提下,用岩芯单点处实测的单点裂缝孔隙度对裂缝解释孔隙度参数进行标定,定量地获得了裂缝孔隙度值。

Abstract

There are two steps to calculate the important parameter of crack porosity in the crack reservoir.First step,we had better identity and find the high conductive crack by the formation ofimage logging.Secondly,we should conform the crack porosity which have been calculated in the nomal logging through using the formation of image logging.Although this paper did not have the data of the formation of image logging,taken the permian crack reservoir for example in the area of Bai 31 ,in the Kelamayi oil field,based on the single point crack porosity which have been analysed on the whole diameter sample,with the means of deep、light dual laterologging crack and compartmentalized the strata which riched in crack through using normal logging ,then conform the porosity parameter in crack explanation by single point crack porosity.At the last,we can quantitatively acquire the crack porosity.
