[摘要] 针对双河油田储层粘土矿物成分及敏感性特征,室内通过实验,优选出增粘剂:HTV-II、抑制剂：KCl、降失水剂：DFD、无渗透膜处理剂：WSTD.在此基础上研究出了一种超低渗透钻井液体系,配方为：3%搬土浆 + 0.08%xy-27 + 0.1%NaOH + 0.2%Na2CO3 + 0.5%HTV-II + 1.2%DFD + 0.08%LN + 3%KCl + 100gCaCO3 + 3%WSTD.并对其流变性、失水造壁性、抗温性、抗盐性、抗钙性、触变性、抑制性、泥饼的抗压强度、储层保护性、中压砂床滤失性、高温高压滤失性进行了评价.实验结果表明,该钻井液体系具有良好的热稳定性,高温老化后,流变性和失水造壁性均满足现场钻井的要求；抗温达130℃；抗盐达25%；抗钙达1.2%；润滑系数为0.15～0.16；钻屑回收率为91.2%,抑制性好；静切力与时间无依赖关系,触变性好；用钻井液污染岩心后,形成泥饼的抗压强度达5.5MPa,截去污染端后岩心渗透率恢复值达85%,储层保护性好；并且在中压砂床上,钻井液侵入深度均小于1.0cm,有很好的防漏堵漏效果.

[Abstract] against Shuanghe oilfield reservoir clay mineral composition and sensitivity characteristics,through indoor experiments,increased flow of Nianji :HTV-II,depressants :KCl,landing stolen form of liquid :name,no film processing agent infiltration :WSTD.On this basis using a ultra low penetration Zuanjingye system formula :Mix 3% move territories 0.08%xy-27 + + + 0.5%HTV-II 0.2%Na2CO3 0.1%NaOH + + + 3%KCl 0.08%LN 1.2%DFD + + + 100gCaCO3 3%WSTD.And to be degenerative,dehydration creates Pik nature,anti-Wen Xing,salt-tolerant nature,anti-calcium nature,Chubianxing,inhibiting,the compressive strength mud pie,reservoir protection,the Chinese pressure sand filter beds sexual misconduct,sexual misconduct high temperature high Yalu:evaluated.Experimental results show that the system has good thermal stability Zuanjingye,high-temperature aging,and degenerative flow of dehydration creates wall drilling site requirements are met; Wen - 1.3 degrees; Salt-tolerant to 25%;-calcium-1.2%; lubricant factor of 91.2% for 0.15~0.16; drilling scrap recovery,inhibiting good; still cutting edge and time-dependent relationship Chubianxing good; Zuanjingye pollution samples used,a mud pie in the compressive strength of 5.5MPa,pollution-off after the restoration of total core penetration 85%,the protective good reservoir; and in the pressure sand bed,are less than 1.0cm depth Zuanjingye penetrated a good proof Thanks results.
