查询词典 limestone

A soft, pure, earthy, fine-textured, usually white to light gray or buff limestone of marine origin, consisting almost wholly (90-99%) of calcite, formed mainly by shallowwater accumulation of calcareous tests of floating microorganisms and of comminuted remains of calcareous algae (such as cocoliths and rhabdoliths), set in a structureless matrix of very finely crystalline calcite.

中文解释=海产起源的石灰石，柔软、纯净、土质、组织精细，通常从白色到浅灰或浅黄色，几乎完全（90-99％）由方解石组成，主要由浮游微生物的粉碎残留物浅水堆积而成，嵌在非常精细的方解石晶体的无定形填质中。

By studying reservoir rock characteristics, diagenesis and physical property, investigation showed that there were distributary channel, branch channel, mouth bar, distal bar, sand sheet, lakeshore, shallow lake and limestone flat . we concluded that the reservoir of N1～N21 is low porosity and permeability reservoir with the types of primary porosity and secondary intergranular porosity, which is in the early diagenetic stage B into the late diagenetic stage A subperiod. The role of effecting reservoir physical property is deposition, cementation, dissolution and tectonic rupture. After researching of reservoir, we divided it into three categories and division the favorable facies belt and relatively favorable. We think that the favorable facies belt is braided river delta front and partly shallow lake in east of the Fault Ⅶ. favorable reservoir is in the first and the second class.

进一步研究了本区碎屑岩储层的岩石学特征、成岩作用特征、物性特征，研究认为该区储集体类型有分流河道砂体、分支河道砂体、河口坝、远砂坝、席状砂砂体、滨湖砂滩、浅湖砂坝砂体及灰坪；N1层属于低孔、特低渗储层，孔隙类型以原生、次生粒间溶孔为主；分析了影响储层物性的因素主要为沉积作用、胶结作用、溶蚀作用和构造破裂作用；进行了储层评价与有利相带预测，将储层分为三类并划分了有利区带、较有利区带，认为Ⅶ号断层以东的辫状河三角洲前缘亚相和部分浅湖亚相是N1的有利储集相带，储层以Ⅰ、Ⅱ类为主。
