摘要:

随着青西油田复杂裂缝型油气藏勘探开发的深入,对双孔介质储层裂缝孔隙的评价不应局限于定性评价,更需要定量评价。针对下白垩统裂缝型储层,阐述了利用岩芯裂缝观测和描述资料对成像测井资料进行标定,结合PoroSpect、FVI、PoroDist等软件计算裂缝孔隙度,以及利用双侧向经验公式计算裂缝孔隙度,从而实现双孔介质储层的定量评价。经青西油田岩芯地面核磁实验验证,与上述测井计算的裂缝孔隙度结果基本一致。该方法应用于青西油田裂缝型储层,实现了油田双孔介质储集层的定量评价,提高了油田地质储量计算的准确性,为油田开发打下了较好的基础。

Abstract: In recent years,with further exploration and exploitation of complicated fracture type oil reservoir in Qingxi Oilfield,a higher requirement is posed to the evaluation of dual-porosity reservoir.The evaluation of fracture pore should not be limited to a qualitative evaluation but extend to a quantitative one.In this paper,the way of calculating fracture porosity is introduced by processing image logging with the use of the softwares of PoroSpect,FVI,PoroDist and using dual laterolog empirical formula to fulfill quantitative evaluation of double porosity reservoir,specific to the lower Cretaceous fracture type reservoir.This way has been applied in fracture type reservoir in Qingxi Oilfield and good application effect is realized.

Key words: fracture porosity, image logging, PoroSpect, PoroDist, dual laterolog
