摘　　要：在沉积相研究基础上,利用岩芯物性分析数据,系统论述了十屋油田营城组—沙河子组储层物性特征及影响储层物性的主要地质因素。认为该油田营城组—沙河子组储层为低孔-特低孔、特低-超低渗储层,储层物性主要受沉积作用和成岩作用因素控制。其中压实作用、胶结作用造成储层物性变差,而溶蚀作用改善储层物性。Based on analysis of sedimentary facies,the reservoir characteristics of Yingcheng-Shahezi formations and the main geological factors influencing their physical properties are systematically studied by using the physical properties data of the cores.It is considered that the K1yc-K1sh reservoirs should belong to the reservoirs in low to extra-low porosity and low to extra-low permeability.The reservoir property is controlled by sedimentation and diagenesis.Compaction and cementation decrease the physical property of the reservoir,while the corrosion reconstructs the reservoirs and provides favorable reservoir space.
