“随钻测量”(简称MWD)技术,在石油工业特别是在海上石油勘探开发作业中得到了广泛的应用。在应用过程中,MWD在种类、元件、结构和性能方面都得到了很大改进。已由最初的作为定向钻井的监控方法而发展成今天提高钻井效率、保证钻井安全、降低作业成本、及时准确地获取钻井和地质资料的重要手段,是现代钻井作业管理的组成部分。MWD仍在继续发展中,但在目前使用过程中还发现了一些问题,因此选用时应谨慎考虑。 MWD technology is widely used in the oil industry, especially in offshore oil exploration and development. In the application process, MWD has been greatly improved in terms of type, element, structure and performance. Has been developed from the original monitoring and control method of directional drilling to become an important means of improving drilling efficiency, ensuring drilling safety, reducing operating costs and acquiring drilling and geological data in a timely manner and accurately. It is an integral part of modern drilling operation management. MWD is still in development, but some problems have also been found during the current use. Therefore, careful consideration should be given to the selection.
