Exact Solution to the Problem of Flow of Slightly Compressible Fluids in a Bounded Confined "Fracture-Pore" Medium and Its Application to Well Testing

摘要: 本文全面求解和研究了有界封闭的“裂缝-孔隙”介质中的弹性渗流问题,进一步揭示和阐明了当忽略岩块系统中的流动时双重孔隙介质中弹性渗流的一些重要特性,并利用所得的解给出通过一系列试井确定有界封闭“裂缝-孔隙”介质地层的所有通常感兴趣的参数的方法.

Abstract: The problem of flow of slightly compressible fluids through a bounded confined "fracture-pore" medium is solved and studied thoroughly in this paper. Some essential natures of flow of elastic liquids through a medium with double porosity under the condition of neglecting the flow in matrix system were revealed and clarified further.The method of estimating all parameters commonly interested in a bounded confined "fracture-pore" medium reservoir through a series of flow tests in wells by use of the solution obtained is presented.
