油气层损害原因浅析

A Brief Analysis for Damage of Gas & Oil Layer

从油藏类型、油气层储渗空间、敏感性矿物、岩石的润湿性、油气层及外界流体性质和工程因素如钻井、完井、试油、射孔、压裂等方面,具体分析油气层损害原因、损害类型及存在现象,为推荐和制定各种油气层保护和解除油气层损害方案提供借鉴。

The damaged reasons and types of oil & gas reservoir and existence phenomena are analyzed from aspects of reservoir type, burial and percolating space of oil & gas layer, sensitive core, moist of rock, fluid property of oil & gas layer, outside and engineering factors, such as drilling, completion, test, perforation and fracture. It provides a reference for suggesting and making protect for every kind of oil & gas layer and plans for releasing damage of it.
