The secondary reserving pores includes structural fissures as well as karren pores and fissures 次生储集空间包括构造缝及溶蚀孔、缝等。
There are three kinds of crack include of structure crack , diagenetic crack and synaeresis crack in this area 该区裂缝主要有构造缝、成岩缝和收缩缝三种类型。
Structural fissures are further divided into five sub - types , with mesh and high angles fissures being dominant 构造缝可进一步分为5种类型,以高角度缝和网状缝为主。
Different groups of fractures are vertically connected in ladder shape and form the fracture net , which improve the permeability of the formations and makes the formations good fracture - pore style reservoirs 不同组系的构造缝纵向上呈阶梯连通,形成空间裂缝网络,极大地改善了侏罗系砂岩储层的渗流能力,使其成为较好的裂缝?孔隙型储层。
Based on the field geologic survey , core observation and well logging fractural identification , it is shown that in the tight reservoir in wubaiti gas pool of eastern sichuan developed structural fractures controlled by local structure 摘要根据野外地面裂缝调查、岩心裂缝观察描述及测井裂缝识别,指出川东五百梯气田致密储集层主要是受局部构造控制的构造缝。
