摘要: 裂缝在低孔低渗储层中所起的作用举足轻重。以东濮凹陷沙三段为例,综合利用野外测量、岩心观察、薄片鉴定、扫描电镜、古地磁定向等方法,对研究区裂缝的类型、发育特征、表征参数等进行了分析,并研究了裂缝与储层含油性、产能及物性的关系。结果表明:东濮凹陷沙三段裂缝按规模可分为宏观裂缝和微观裂缝,宏观裂缝规模较大,微观裂缝发育密集;裂缝孔隙度可作为裂缝发育程度的综合定量评价参数,宏观裂缝平均孔隙度为0.048%,微观裂缝平均孔隙度为0.54%;裂缝既可以作为油气储集空间,又可作为油气运移通道,同时,还可以沿裂缝产生次生孔隙带,从而改善储层物性,提高储层含油概率及产能;宏观裂缝主要改善储层渗透率,起渗流作用,微观裂缝可增大储层储集空间,连通储层孔隙,宏观裂缝和微裂缝形成的一个连通立体的网络控制着油气的运移和富集。

Abstract: Fractures have a pivotal role in low-porosity and low-permeability sandstone reservoir.In order to study the relationship between fractures and the oil-bearing strata,production capacity,physical properties of reservoirs,the third member of Shahejie Formation in Dongpu Depression is selected as a subject,various techniques such as outcrop measurement,core overview,thin sections analysis,scanning electron microscopy and paleomagnetic core orientation were used.The types,characteristics,parameters of fractures were analyzed.The research results indicated that fractures can be divided into two categories according to their size which are the macro-fractures and micro-fractures.The size of macro-fractures is larger,while the development of micro-fracture is intensive.The porosity of fractures can be used as comprehensive quantitative evaluation parameters of fracture development.The macro fractures have porosity of 0.048% on average,and micro fractures have porosity of 0.54% on average.Fractures not only can be used as reservoir space,but also can be used as acid fluid flow channel.Flowing fluid in the fracture also can form dissolution pores,so fractures can improve the property,oil-bearing probability and capacity of the reservoir.Macro-fractures are mainly to improve the reservoir permeability,which play an important role in fluid seepage.Micro-fractures can increase the reservoir space and connect the pore of reservoir.Macro-fractures and micro-fractures formed a three-dimensional network which controls the oil and gas migration and accumulation.
