Formation of laumontite of the upper triassic yanchang group in ordos basin and its effect on reservoirs 靖安油田上三叠系延长统浊沸石的形成及对储层的影响
2.
The main diagenetic minerals of the reservoir rock are chlorite , laumontite , calcite and authigenic quartz and so on 在成岩作用研究的基础上，建立了成岩及孔隙演化模式。
3.
At the late diagenesis phase , the dissolution of frame grains , especially the dissolution of felspar and laumontite , is the key to form secondary porosity 朵状砂体的大小直接控制油藏的范围及规模，靖安地区的主要油藏多沿不同的朵状体成排分布。
4.
The cementation of laumonite , calcite and chlorite , compact and pressure solution , as well as the dissolution of laumontite , feldspar are also of main factors which affect reservoir properties 方解石、绿泥石、浊沸石的胶结作用、压实压溶作用和浊沸石、长石的溶解作用也是影响储集性能的主要因素。
5.
The metallic mineral has very few content ( 1 % - 2 % ) , the mineral of ore is mainly of pyrite , chalcopyrite , limonite , aurum and electrum etc . the gangue mineral is composed of chalcedony , micro grained quartz , calsite , sericite , adularia , aragonite , chlorite , laumontite , pyrophyuite , kaolinite and so on , which show the typical mineral assemblage of epithermal 矿石为典型少硫化物型，金属矿物含量极少( 1 - 2 ) ，主要有黄铁矿、黄铜矿、褐铁矿和自然金、银金矿等。主要脉石矿物有玉髓、微粒石英以及方解石、绢云母、冰长石、文石、绿泥石、浊沸石、叶腊石、高岭石等，属典型低温矿物组合。
