本文介绍了正电胶-聚合物钻井液的配方组成、室内性能测试结果和现场应用实例。正电胶与聚合物复配使用时有很好的互补性，得到的钻井液抑制能力强，失水造壁性好，动塑比高，卡森极限粘度低，能显著提高泥页岩稳定性，清洁井眼，提高机械钻速，应用于定向井取得了成功。这是一种实用价值很高的钻井液。 This paper describes the composition of positive rubber - polymer drilling fluid composition, indoor performance test results and field application examples. The positive rubber and polymer compounding have very good complementarity, the resulting drilling fluid inhibition ability, good water lost wall build, high plasticization ratio, low viscosity of Carson, can significantly improve the stability of shale Wells, clean boreholes, improve ROP, applied to the directional well has been successful. This is a practical drilling fluid of high value.
