The study of diagenesis and its stages let us think that the pingdiquan formation belongs to period " a " of early diagenesis 成岩作用及阶段研究认为二叠系平地泉组属早成岩“ a ”期。
Diagenesis and controlling factors of the turbidite reservoir of sub - middle of the third member of shahejie formation in niuzhuang sag 牛庄洼陷沙三中亚段浊积岩储层成岩作用及主控因素分析
Due to low burying depth and weak diagenesis , the formation is loosely solidified , which shows an immature stage of diagenesis 馆上段地层埋藏较浅，成岩作用弱，岩石疏松，为早期成岩阶段的产物。
Diagenesis of chang2 reservoir of upper triassic series in zichang oilfield and the factors of influencing the physical property of the reservoir 子长油田上三叠统长2油层组储层成岩作用及物性的影响因素
Burial diagenesis causes a progressive transformation of smectites , the end - products being dependent on ph and pore water chemistry 埋藏成岩作用可使蒙脱石进一步转化，最终产物决定于ph值及孔隙水的化学性质。
However , the diagenetic numerical modeling is not perfect , to say nothing of porosity prediction . overpressures raise the activity energy of diagenetic reactions 超压对成岩作用抑制的实质是增加了成岩反应的活化能。
Finally regional distribution of reservoir has been predicted . study suggests that feixianguan formation is essentially controlled by sedimentation and diagenesis 研究表明，飞仙关组储层主要受沉积作用和成岩作用的控制。
Its range is relatively small . the latter ' s range is broad , belonging to the gentle - slope style . the bottom stratum developed a set of turbidite - fan 5 、研究了以欧39井沙三下为代表的储层的成岩作用，为评判储层的优劣提供了依据。
Fractures in reservoirs are defined as macroscopic unconnectedness , which existed in rocks naturally and formed by deformation or physical diageneses 储集层裂缝是指由变形作用或物理成岩作用形成的，在岩石中天然存在的宏观面状不连续。
Ordovician carbonate rock bed of ordovician reservoir in qianmiqiao buried hill experienced two times of karst exposure and the post plaeogene deep - buried diagenesis 摘要千米桥潜山奥陶系储层经历了两次裸露岩溶及古近纪后的深埋藏成岩作用。
