| 1. | The dolomitization is the base of forming high quality reservoirs 白云石化作用是形成优质储层的基础。 |
| 2. | Crystalline dolostone is formed by seepage - reflux dolomitization and burial dolomitization 晶粒白云岩有两种成因:一为回流渗透白云石化;二为深埋藏白云石化。 |
| 3. | The diageneses which are constructive to the reservoirs are mainly dolomitization and burial dissolution 对储层起建设性作用的成岩作用主要有白云石化作用、埋藏溶解作用。 |
| 4. | 2 ) the contraction action of granulations can form the pore of dolostone reservoir in the course of dolomitization 2 )在白云石化过程中岩石粒屑的收缩作用可以形成白云岩储层孔隙。 |
| 5. | According to the mechanism of dolomitization , it can be divided into penecontemporaneous dolostone and post - penecontemporaneous dolostone 白云岩可据白云石化作用的机理和时间分为准同生白云岩和准同生后白云岩两大类。 |
| 6. | The primary rocks were sparry oolitic limestone and micrite oolitic limestone , but dolomitization destroyed the original sedimentary textures 原生岩石为亮晶鲕粒石灰岩和泥晶鲕粒石灰岩,白云石化作用使其岩石结构大多遭受破坏。 |
| 7. | The genetic types include weathering , regional meteoric corrosion , regional dolomitization regional paleokarstification , regional dedolomitization and regional fresh - water cementation and filling 研究区存在包括风化、区域性大气淡水溶蚀、区域性白云岩化、区域性古岩溶、区域性去白云岩化和区域性淡水胶结充填等6种岩溶作用的层序成因类型。 |
| 8. | These characteristics have close relation with transgression from eastern to western . 4 . reefs undermined various and complicated diagenesis , in which cementation , dolomitization and corrosion etc . play main roles in the history of reef diagenesis 4礁岩的成岩作用具多样性和复杂性,其中泥晶化、填积、胶结、白云化和溶蚀作用最为重要。 |
| 9. | The dolostones have experienced several types of post - depositional diagenetic modifications , of which dolomitization , dissolution , recrystallization and tectonic stress processes have exerted an important effect on porosity and permeability 认为该白云岩在沉积期后变化中经历了多种成岩作用改造,其中影响白云岩储集性的作用主要有白云石化作用、溶蚀作用、重结晶作用和构造应力作用,对白云岩孔渗改善起了积极作用。 |
| 10. | Main diagenesis of carbonate reservoir as following : ( 1 ) . there are five types of dolomitization : evaporative pumping , seepage reflux , mixing and deep buried . ordivician main type of dolomite of qianmiqiao buried hill in dagang oilfield is elogenetic micrite and microspar dolomite 5 、对碳酸盐岩储层的成岩作用分析认为: ( 1 )白云岩化作用有四种类型:蒸发泵白云化作用、回流渗透白云化作用、混合水白云化作用、深埋藏白云化作用。 |
