泥浆转化为水泥浆(Mud-To-Cement，简称MTC)技术是利用钻井液的降失水性和悬浮性，通过加入廉价的高炉水淬矿渣(BFS)和激活剂(BAS)，将钻井液转化为完全可以与油井水泥浆相媲美的固井液。固井作业中，因常规水泥与钻井液难以相容，造成固井水泥污染，严重影响固井质量。设计密度为1.50～1.60g/cm3泥浆固井液体系，该体系以矿渣为水化材料，再加入激活剂，通过室内试验和现场应用，结果表明，该技术能提高固井质量，降低固井成本。在中原油田MTC固井技术首先在钻井三公司桥57井等10口井的中完固井中获得了成功现场应用，取得良好的经济效益和社会效益，并推广应用。

Mud-To-Cement (MTC) is the technology that may convert drillingfluid to cement slurry by adding cheap blast furnace slag (BFS) and stimulated agent and making use of the properties of fluid loss control and suspension of drilling fluids. As we know, ordinary cement is usually incompatible with drilling fluids and it can cause contamination of cement and has a very bad influence on the performance of cement slurry. A mud-cement system that has 1.50～1.60 g/cm3 in density has been designed. Results of tests and field application indicate that this system has advantages of good compatibility, high compressive strength and adjustable thickening time. In Zhongyuan oilfield, it was firstly applied in ten wells of the Third Drilling Company and got great success. In this way, the cost of cementing can be decreased greatly. Therefore this technology has been popularized in this area.
