摘　　要：通过对文203块储层的岩性、物性、孔隙结构、填隙物成分及地层流体的分析和研究,探讨了开发过程中引起储层伤害的潜在因素,认为矿物低的结构成熟度、水敏和应力敏感性、有机垢、注入水水质为储层伤害的内在因素;长期大生产压差条件下,强注强采是导致储层伤害的外在因素。内外因相结合导致储层严重伤害。Through analysis on lithology,property,pore structure,interstitial material and formation fluid in Wen 203 Fault Block reservoirs,it discusses potential factors of reservoir injury in development process.It shows that low maturity of mineral,water sensitivity and stress sensitivity,organic scale and injected water quality are internal factors of reservoir injury.In condition of long-term high production pressure difference,forced injection and forced production are external factors.Internal and external factors cause together serious injury of reservoir.
