diagenetic process meaning in English
成岩过程
岩化作用
Examples
- During diagenetic process , the main factor destroying porosity is function of pressure and cementation . secondary porosity formem formed by unsteady mineral is beneficial to formation ' s development
成岩作用中，压实作用、胶结作用、自生粘土矿物的沉淀是破坏孔隙的主要因素；不稳定矿物溶蚀形成的次生孔隙有利于储层的发育。 - These strata of basin are made up of cretaceous period , tertiary period and quaternary period . tertiary period is the major sediment in the basin and the biggest thickness is up to five thousand meters . this thesis studies the petrology and characteristic of the diagenetic process of the reservoir
盆地的沉积岩系主要由白垩系、上下第三系和第四系组成，下第三系是盆地中的主体沉积，最大厚度5000米，分为万昌组、永吉组、奢岭组、双阳组。 - During diagenetic process , there may exist the fractional crystallization of clino - pyroxene , plagioclase , olivine and ti - fe oxide , and the accumulation of olivine . the alkalic - ultramafic dikes formed by low degree partial melting ( 3 . 4 % ) of enriched mantle , consist of single olivine pyroxenolite , the dominating olivine fractionation is evident
成因上为富集地幔部分熔融作用的结果，但在成岩过程中也可能存在单斜辉石、斜长石、橄榄石和ti - fe氧化物等矿物的分离结晶作用。 - They are skeletal sand bodies in system of delta and places of most reservoir distribution . the diagenetic processes that govern reservoir properties include the extent of compaction , cementation and dissolution of grains . we recognize that at the early diagenesis phase , mechanical and chemical compaction is very strong , which reduced the original porosity
河口砂坝多位于分流河道或次一级分流河道河口部位，向湖盆中心呈放射状分布，因而河口砂坝砂体多构成朵状砂体，覆盖面积大、连片好，砂体厚度大，是本区已知油藏主要分布区。 - Also , the microscopic analysis of pore structure with different fractal feature comes to the conclusion that the reservoir rocks with similar fractal nature have similar pore type , depositional environment and diagenetic process , and the fractal dimension sill increase with pore radius ( or total number of pore throats ) decreasing
此外，根据对不同分形特征孔隙结构微观分析，得出分形特征相似，其孔隙类型，沉积成岩过程相似，当喉道半径变小（或孔隙总数减少） ，分形维数增加的结论。
