摘要
针对疏松砂岩储层的特点,通过人工压制岩板(模拟疏松砂岩储层)开展了静态滤失实验,研究了缝内压差与渗透率对累计滤失液量及滤失系数的影响.分别测试100 mD、1500 mD和3000 mD模拟岩板在0.5～6 MPa压差条件下的滤失情况.结果发现,累计滤失液量受控于缝内压差与渗透率,滤失系数受控于缝内压差.
Abstract
Based on the characteristics of loose sandstone reservoirs,artificial compaction of rock plates was used to simulate loose sandstone res-ervoirs and static filtration experiments were conducted to study the effects of pressure difference and permeability within fractures on the cumu-lative fluid loss and filtration coefficient.It tested the filtration performance of 100 mD,1500mD,and 3000mD simulated rock slabs under pres-sure differential conditions of 0.5MPa-6MPa,respectively.The results showed that the cumulative filtrate loss was controlled by the pressure difference and permeability within the fracture,and the filtration coefficient was controlled by the pressure difference within the fracture.
