摘要

摘要: 大位移井高温储层水基钻井液在高负荷、高盐度、高温条件下，液体润滑剂的润滑性能不足，导致憋钻具、卡钻和钻具磨损等问题，实验室合成了一种硫化脂肪酸酯，将其与润滑剂复配后得到复合硫剂（QT311），添加至HTFlow高温高压水基钻井液中，能够提升钻井液的润滑性能。通过四球试验机测试可知，添加1%QT311后，其COF能够下降64%，磨斑直径降低43%，润滑性能优于几款常用市售钻井液用润滑剂。通过电镜分析摩擦副表面，发现硫剂在摩擦过程中发生摩擦化学反应生成硫-铁极压膜，从而提升钻井液的减摩性能，且该剂在HTFlow钻井液体系中表现出优异的配伍性、抗水解性能、抗盐及抗温性能。试验结果为钻井液用润滑剂的进一步研究提供参考。

Abstract: In high temperature extended reach well drilling, the water-based drilling fluids are generally treated with liquid lubricants to alleviate friction. In high density, high salinity and high temperature conditions, the lubricity of the liquid lubricants is not enough to reduce the friction to the required level, causing from time to time downhole troubles such as halting of drilling string, stuck pipe and wear and tear of drill tools. To solve these problems, a sulfurized fatty acid ester is synthesized in laboratory and is compounded with lubricants to obtain a compound lubricant QT311. Adding the lubricant QT311 into the HTFlow high temperature high pressure water-based drilling fluid greatly improves the lubricity of the drilling fluid. Testing the QT311 treated HTFlow drilling fluid on four-ball friction tester shows that treatment of 1%QT311 reduces the coefficient of friction by 64% and the diameter of the wear scars is reduced by 43%. These results indicate the QT311 as a lubricant is superior to several widely used commercial lubricants. Analysis of the surface of the friction pair with SEM shows that QT311 react chemically with iron during friction to form sulfur-iron extreme pressure membrane, thereby improving the friction-reducing performance of the drilling fluid. The laboratory experiments also show that QT311 has excellent compatibility with the HTFlow drilling fluid, anti-hydrolysis performance, salt resistance and high temperature resistance. The experimental results have provided a reference for further studies on drill-in fluid lubricants.
