摘要

摘要: 润湿剂是油基钻井液关键处理剂之一，目前尚未建立油基钻井液润湿剂评价标准。针对现有油基钻井液润湿剂评价方法的不足，基于油相塑性黏度、重晶石颗粒在油相中沉降速率、重晶石颗粒在油中的沉降体积等参数，建立了一种新的简单易行的油基钻井液润湿剂评价方法。选用了3种油基钻井液润湿剂A、润湿剂B及润湿剂C进行了润湿性能评价，基于以上评价参数，润湿剂的润湿性能优劣顺序依次为润湿剂C、润湿剂A和润湿剂B。为进一步验证所建立的油基钻井液润湿剂评价方法的可行性，通过实验评价了以上3种润湿剂的接触角以及加入以上3种润湿剂后油基钻井液的性能，研究结果表明，所建立的新的评价方法能有效评价油基钻井液润湿剂的润湿性能。

Abstract: Wetting agent is a key additive of oil base drilling fluid. Presently although there are a lot of methods for evaluating the performance of the oil base mud wetting agents, there is no standard for the evaluation. A new simple and easy method has been established to eliminate the deficiencies the old methods have, and it is based on the plastic viscosity of the oil phase, the settling velocity of barite particles in the oil phase and the volume of barite particles that settles. Three oil base mud wetting agents were studied in our studies, which are wetting agent A, wetting agent B and wetting agent C. Using the above evaluation parameters, the performance of the three wetting agents is in an order of C > A > B. To verify the feasibility of the new method, the contact angles of the three wetting agents and the properties of an oil base drilling fluid sample treated with A, B and C, respectively. The results showed that the new method is able to be used to effectively evaluate the wetting performance of wetting agents used in oil base drilling fluid.
