德惠断陷含气储层特征及其控制因素
|
摘要
为研究德惠断陷储层特征及主控因素,利用镜下薄片、铸体薄片、X射线衍射及扫描电镜等多种手段,对该区五套含气层系储层的储集空间特征、储层物性及影响储层物性的主要因素进行了探讨。结果表明:德惠断陷火石岭组-泉头组岩性既有粉-细砂岩、砂砾岩等的碎屑岩类,也出现火山熔岩、火山碎屑岩等的火山岩类。无论碎屑岩储层还是火山岩储层,孔、渗性均较差。该区碎屑岩为河流相、滨-浅湖相、辫状河三角洲相及扇三角洲相沉积,整体上石英含量少,长石含量偏高;其储层物性最终控制因素为各种成岩作用。而裂缝规模、裂缝成因、后期成岩改造作用等直接影响火山岩储层的储集性能。溶蚀作用为改善这两类储层物性的主要因素。
In order to study reservoir characteristics and main control factors of Dehui fault depression, cast sheet, thin section, X-ray diffraction and scanning electron microscope were used to investigate the characteristics of reserving space, reservoir physical properties, and the main factors affecting the reservoir physical properties of the five sets of gas bearing formations in this area. The results show that there are not only the clastic rock of aleuvite, fine sandstone and gravel, but also the volcanic rock, such as volcanic lava and volcanic clastic rock for the reservoir lithology in Dehui fault depression. Whether clastic rock reservoir or volcanic rock reservoir, both porosity and permeability are poor. The main sediments here are of fluvial facies, shore lake faces, shallow lacustrine facies, braided river delta facies and fan delta facies. And the content of quartz is little, but that of feldspar is high. The final control factors of clastic reservoir physical properties are kinds of diagenesis. And the crack scale, causes of cracks, and the transformation of metaharmosis directly influence the reservoir properties of the volcanic reservoir. Corrosion is the main factor to improve the physical properties of these two kinds of reservoirs.
