The Study on well Pattern Adaptability of Single Sand-Body

Abstract

According to sand-body genetic types, single sand-body is divided into five types include the polytectonic river-channel superimposed type, branching-river channel type, single river-channel type, sheet sand type and lentoid sand type. The use of multi-factor analysis to determine the index weight of control-degree of water flooding, recovery percent, water content, injection-production ratio and pressure distribution in different types of single sand-body, calculate different types of comprehensive Index of single sand-body adaptability. And analyze injection-production system to the well pattern adaptability in different types of single sand-body.
