Wellbore instability caused by water invasion is the main problem in oil and gas drilling operation. This study reports the utilization of a hydrophobic‐associated polymer‐based laponite nanolayered silicate composite as a filtrate reducer in water‐based drilling fluids (WDFs). The thermal performance and micromorphology of the composite were analyzed by thermogravimetric analysis, transmission electron microscope, and field emission scanning electron microscopy. The results indicated that the composite possessed a “bean pod” structure and a good thermal stability. The rheological properties of the composite solution were evaluated. The results showed that the hydrophobic association interaction of the composite is weak but existent, and the crosslink network structure is variable. The applied performances of WDFs containing the composite were also evaluated. Evaluation results showed that the composite could improve the properties of the thermal stability, salt tolerance, and fluid loss control of WDFs. The particle size distribution of WDFs and the micrographs of filter cakes explained the improving. The composite was expected to be applied as an efficient filtrate reducer for developing high performance drilling fluids. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2020, 137, 48608.

疏水缔合的聚合物基锂皂石纳米层状硅酸盐复合材料，作为高温下水基钻井液的减滤液剂

由水入侵引起的井筒失稳是油气钻井作业中的主要问题。这项研究报告了疏水性聚合物基锂皂石纳米层状硅酸盐复合材料在水基钻井液（WDFs）中作为滤液减少剂的利用。通过热重分析，透射电子显微镜和场发射扫描电子显微镜对复合材料的热性能和微观形貌进行了分析。结果表明该复合材料具有“豆荚”结构和良好的热稳定性。评价了复合溶液的流变性。结果表明，复合材料的疏水缔合作用较弱但存在，且交联网络结构是可变的。还评估了包含复合材料的WDF的应用性能。评价结果表明，该复合材料可以改善WDF的热稳定性，耐盐性和失水率控制性能。WDF的粒度分布和滤饼的显微照片说明了这种改进。该复合材料有望被用作开发高性能钻井液的高效降滤液剂。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学该复合材料有望被用作开发高性能钻井液的高效降滤液剂。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学该复合材料有望被用作开发高性能钻井液的高效降滤液剂。分级为4 +©2019 Wiley Periodicals，Inc.J.Appl。Polym。科学2020，137，48608。
