摘　　要：自吸现象已成为低渗透油气藏开发过程中普遍关注的问题,但自吸规律研究及自吸实验的开展大多从宏观方面进行,而模拟实际油藏条件下毛细管的微观研究比较少。用石英玻璃刻微管束来模拟低渗砂岩毛细管自吸效应,通过实验测得常温常压下的毛细管自吸量随时间的变化,并对实验结果进行了数据处理和分析。Self-absorption phenomenon becomes the common problem for low permeability reservoirs development. Most of the research on the law of self-absorption and self-absorption experiments are studied fi＇om the macro aspects, while the micro-capillary study is less under the simulation of actual reservoir. In this paper, it uses quartz glass, engraved with micro-capillary tubes to simulate the low-permeability sandstone self-absorption effect. It measures changes of self-absorption quantity with time under normal temperature and pressure, and analyzes the experimental results with data treatment.
