泥质岩和砂岩渗透率特征及其影响因素初步分析

The preliminary analysis of the permeability characters of mudstone and sandstone and it's effects

泥质岩和砂岩是油气成藏过程的两种重要输导介质,其渗透率的大小反映了其输导性能的好坏.前人对泥质岩渗透率特征及其影响因素和砂岩渗透率特征及其影响因素做了大量研究.对前人研究成果进行了分析,并指出了其需要解决的问题:泥质岩和砂岩在破裂前后渗透率的变化特征;泥质岩和砂岩的平行层面和垂直层面渗透率的差异研究;外加应力与裂缝成不同角度时,应力增减对裂缝渗透率变化的影响.

Mudstone and sandstone are the two important medium of the process in the hydrocarbon accumulation,it s size of the permeability reflects it s transportation ability.People have done a lot of research about mudstone s permeability and it s effects,and sandstone s permeability and it s effects.This article analyze these studies and point out some questions:Mudstone and sandstone s change characters before and after the stone broken;The reaserch of the permeability s change characters of the mudstone and sand...
