Oil-based drilling fluid plugging cement paste and application thereof
The invention belongs to the technical field of oil and gas well drilling, and particularly relates to cement paste for oil-based drilling fluid leaking stoppage and application of the cement paste. The cement paste for leaking stoppage of the oil-based drilling fluid is prepared from the following raw materials in parts by weight: 100 parts of cement, 40 parts of water, 4 parts of a fluid loss agent and 0.0075-1.5 parts of a compatibilizer. Compared with the traditional cement paste, the plugging cement paste provided by the invention has excellent compatibility with the oil-based drilling fluid, and can better solve the problem of low plugging success rate caused by poor compatibility of the cement paste and the oil-based drilling fluid in the operation process of treating leakage of the oil-based drilling fluid by cementing a plug.
本发明属于油气井钻井技术领域，具体涉及一种油基钻井液堵漏用水泥浆及其应用。所述的油基钻井液堵漏用水泥浆，以重量份计，其原料组成为：100份的水泥，40份的水，4份的降失水剂，0.0075~1.5份的增容剂。本发明提供的堵漏水泥浆与传统水泥浆相比，具有与油基钻井液优异的相容性，可较好的解决打水泥塞治理油基钻井液漏失作业过程中遇到的水泥浆与油基钻井液配伍性差，导致的堵漏成功率低的难题。
