泥浆是钻探的血液。以聚丙烯酰胺泥浆为中心的三大技术在石油钻探推广后,钻井效率翻了一番、打出来很多优质高产井,促进了我国钻探事业的向前发展。我国泥浆工艺从延用多年的细分散,粗分散体系发展到不分散体系,是泥浆工艺技术水平进入了一个新阶段。在水文地质钻探中,经常遇到第四纪松散地层,需要泥浆作为冲洗液,但是,泥浆 Mud is drilled blood. Three technologies centering on polyacrylamide mud After drilling for oil drilling, drilling efficiency doubled and many high-quality and high-yield wells were drilled, which promoted the development of China’s drilling industry. China’s mud from the extended use of many years of finely dispersed, coarse dispersion system developed to non-dispersed system is the level of mud technology has entered a new stage. In hydrogeological drilling, quaternary loose formations are often encountered and mud is required as a flushing fluid, however, mud
