川西坳陷什邡-德阳-广金地区蓬三段致密储层物性特征及其控制因素研究
|
摘要
依据大量的薄片资料及压汞资料,研究了川西坳陷什邡-德阳-广金地区蓬三段砂岩储层的物性特征及孔隙结构特征,认为研究区储层整体上是低孔、特低孔-超低渗致密储层,并将蓬三段储层孔隙结构划分为I、II、III、IV四类。控制储层发育的因素主要是沉积环境及成岩作用。其中,沉积环境主要是通过岩石的矿物成分及粒度等体现。研究区蓬莱镇组地层整体处于中成岩A阶段,对研究区储层影响较大的成岩作用包括压实、胶结、溶解及交代作用,其中压实、胶结和交代作用使储层物性变差,而溶解作用改善储层的孔渗性。
Based on the datas of flake and mercury injection information,to study the physical characteristics and pore structure characteristics about the third of Penglaizhen formation,west Sichuan Foreland. That the study area is on the whole low porosity reservoirs,especially low porosity-especially low permeability tight reservoir. Divided the pore structure of the third of Penglaizhen formation into I,II,III,IV four categories. The factors controlling the development of the reservoir is mainly sedimentary environment and diagenesis. The sedimentary environment mainly through the mineral composition and size of rocks and other expression. The greater impact on the study of the reservoir diagenesis is mainly compaction,cementation and dissolution.
