根据秦家屯油田登娄库组小Ⅰ段油层大量分析化验数据,对储层的岩性、物性、孔隙结构及分布特征研究表明:该储层属中孔、中渗储层,油藏在宏观上受断层影响具有一定的不连续性,但在微观上却表现出较高结构成熟度、较低成分成熟度的特点。储层岩石为长石砂岩,储集空间以原生粒间孔为主。研究成果为油田合理开发提供了科学依据。
Based on a large amount of laboratory analysis data of small oil reservoir in Denglouku Formation in Qinjiatun Oilfield, the lithology, physical property, pore structure and distribution characteristics of the reservoirs show that the reservoir is a medium-porosity and medium-permeability reservoir with a Macroscopically, it is affected by faults with some discontinuities, but it shows the features of higher structure maturity and lower composition maturity at the microscopic level. The reservoir rock is feldspar sandstone, and the reservoir space is dominated by primary intergranular pores. The research results provide a scientific basis for the rational development of oilfields.
