摘要

摘要: 研制出了一种逆乳化凝胶润滑封堵剂XZ-RF，分析了其作用机理，对其润滑性和封堵性进行了评价。实验结果表明，XZ-RF具有很好的润滑能力，1%的加量即可将膨润土浆摩阻系数降低60%，当XZ-RF加量为3%时，可将膨润土浆摩阻系数降低80%以上，且XZ-RF在聚合物钻井液能表现出良好的润滑性；XZ-RF具有好的抗温、抗盐封堵能力，可将膨润土加重浆160℃高温高压滤失量降低65.8%，将欠饱和盐水加重浆120℃高温高压滤失量降低86.8%。XZ-RF在新疆油田2口预探井进行了现场应用，均取得了较好的效果，而且该产品无荧光，具有更大的应用范围。

Abstract: An invert emulsion gel lubricating plugging agent, XZ-RF has been developed. Evaluation of XZ-RF showed that it had good lubricating ability; addition of 1% XZ-RF reduced the friction coefficient of bentonite mud by 60%, and 3% of XZ-RF reduced the friction coefficient of bentonite mud by more than 80%. XZ-RF showed good lubricating performance in polymer drilling fluid. XZ-RF also showed good plugging performance. A weighted bentonite mud treated with XZ-RF had HTHP filter loss reduced by 65.8% at 160℃. An under-saturated weighted brine mud treated with XZ-RF had HTHP filter loss reduced by 86.8% at 120℃. XZ-RF is a drilling fluid additive free of fluorescence, it has been successfully used in drilling 2 exploratory wells in Xinjiang Oilfield.
