| 1. | Porosity may be classified according to the mode of origins ( 1 ) original and ( 2 ) induced 按其原始形态,孔隙度可分为原牛孔隙度和次生孔隙度。 |
| 2. | The diagenetic environment results in different water - rock reaction and development of secondary porosity 成岩环境在一定程度上影响了水岩反应及次生孔隙发育。 |
| 3. | Materials having induced porosity such as the carbonate rocks have even more complex pore configurations 类似碳酸盐岩这种含有次生孔隙结构的物质具有更为复杂的孔隙构型。 |
| 4. | The physical properties are mainly dominated by thress factors : solution , sedimentary facies and buried depth 主要发育次生孔隙,储层物性受溶蚀作用、沉积相、埋藏深度三个因素的控制。 |
| 5. | Rocks having original porosity are more uniform in their characteristics than those rocks in which a large part of the porosity is induced 具有原生孔隙度的岩石比次生孔隙度占大部分的岩石在性质上更具有一致性。 |
| 6. | Induced porosity is typified by fracture development as found in some shales and limestones and by the rugs or solution cavities commonly found in limestones 次生孔隙度是以某些页岩和石灰岩的裂缝和石灰岩中的岩穴和溶洞为代表。 |
| 7. | The preserved average porosity is 10 . 1 % at present . the main reservoir space of chang 4 + 52 ~ chang 62 sandstone in the area is secondary pores , especially the secondary intergranular pores 研究区储层砂体的储集空间以次生孔隙为主,并以次生粒间孔隙占优势,次为填隙物内溶孔、粒内溶孔。 |
| 8. | 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。 |
| 9. | The diagenesis may result in the variations in pore structures of sandstone reservoirs ; the compression and cementation may lead to the decrease in valid primary porosity of sandstones , and the secondary porosity generated by solution may serve as main oil storage spaces 压实作用和胶结作用降低了砂岩的原生孔隙度,溶解作用产生的次生孔隙成为主要的汕气储集空间。 |
| 10. | The main principle problems in the study area include , the diagenetic history , the type of sandstone , the source of the sandstone type , the source of cement , the source rocks for generation petroleum , the formation of secondary porosity , the oil migration , and reservoir quality 论文在成油体系分析的基本思路指导下,探讨东营凹陷南部斜坡带孔店组储集砂岩的矿物组成、物源方向、胶结作用、成岩作用动力学过程,以及次生孔隙发育与油气生成聚集的关系。 |
