matrix porosity meaning in English

基岩孔隙度
基质孔隙度

Especially for matrix porosity and fracture porosity , the thesis took a way of multiple curves integrated discrimination instead of only using acoustic curve at past . during the period of the thesis research , a project about volcanic rock in liaohe basin started . so a lot of volcanic data in liaohe basin were gotten . the thesis processed and interpreted 31 volcanic rock wells and test the interpretation results with the well data which is already known
在论文的研究进程中，恰逢《辽河油田火山岩储集层测井解释评价》课题开题，因此使得本论文能够得到相对齐全的有关火山岩的资料和较多的( 31口井)单井测井资料，并根据此方法对这31口井进行了单井测井处理和解释，将处理结果与火山岩实际地质资料对比，吻合情况较好。
4 ) the major reservoirs are dominated by types of medium matrix - pores and developed fractures , with features of " large pores and small fissures " and " large fractures and micro pores " . statistic analysis shows that when matrix porosity is less than 5 % or fractural density lower than 1 piece per meter , the volcanic rocks are difficult to become or shape reservoirs
该区主要储层为基质孔隙中等裂缝发育型， “大孔小缝”或“大缝小孔”均可形成储层，经统计分析，当基质孔隙度低于5及裂缝密度小于1条/ m的地层，不易形成储集层。
