白庙气田储层伤害因素分析及配套保护措施

外来固相、滤液及生产或作业压差、生产时间等工程因素可造成或加重气层的伤害程度，而储层孔隙结构、润湿性、粘土矿物类型和含量等是造成气层伤害的潜在因素。通过对白庙气田储层敏感性分析及工作液对储层的伤害评价，在气田开发过程中有针对性地制定出气层保护配套措施，减少了储层伤害，提高了气田开发效果。

Potential Factor Study of Reservoir Damage and Proper Measures of Reservoir Protection in Baimiao Gas Field

Engineering factors as external solid phase and filtrate,producing or operating pressure drawdown may cause or aggravate the damage of gas reservoir.But reservoir pore structure,wettability and the type and content of clay mineral are the potential factors which result in formation damage.Under the study of the sensitivity and the damage evaluation by work fluids of gas reservoir in Baimiao gas field,the proper measures are directly taken to protect gas reservoir through out the development of gas field,having decreased the degree of damage and improved the development effect of gas field.
