摘要
苏里格气田其气井存在单井产量低、压力下降快等问题,研究储层对物性的控制作用就显得十分重要.本文在前人工作基础上,结合野外露头观察、岩心观察描述,深入分析苏东地区大量的储层岩矿、物性、铸体、电镜、阴极发光等测试分析资料,认为(1)苏东地区沉积相类型为河流相,砂体粒度较粗、分选较好,砂体类型主要为孤立性、下切堆叠型以及离散堆叠型;(2)苏里格气田苏东地区盒8段的砂岩碎屑成分中的石英、高岭石、绿泥石对影响物性起到了主导作用;(3)成岩作用中的溶蚀作用也直接控制了储层物性.研究成果对推进苏东地区的勘探开发有一定理论指导意义.
Abstract
There are many problems in Sulige gas field,such as low production and rapid pressure drop,so it is very important to study the control effect of reservoir on physical properties.On the basis of previous work,combined with field outcrop observation and core observation description,this paper deeply analyzes a large number of reservoir rock and mineral,physical properties,cast,electron microscopy,cathodoluminescence and other test analysis data in eastern Sulige.It is concluded that(1)sedimentary facies in eastern Sulige are fluvial facies with coarse sand body size and good sorting,and sand body types are mainly isolated,downcut stacked and discrete stacked.(2)The quartz,kaolinite and chlorite in the detrital composition of the sandstone of He 8 member in the eastern area of Sulige Gas Field play a leading role in influencing the physical properties;(3)Dis-solution in diagenesis also directly controls reservoir physical properties.The research results have a certain theoretical significance for promoting the exploration and development of the eastern Soviet area.
