随钻测井的昨天、今天和明天

The Logging While Drilling: Past,Present and Future

随钻测井(LWD)技术的萌芽只比电缆测井晚10年。由于基础工业整体水平的制约,随钻测井技术在前50多年发展缓慢。最近20年来,随钻测井技术获得全面快速的发展,目前已具备了与电缆测井对应的所有技术,包括比较完善的电、声、核测井系列以及随钻核磁共振测井、随钻地层压力测量和随钻地震等技术。随钻测井已成为油田工程技术服务的主体技术之一,其业务收入和工作量快速增长。勘探开发生产的需要仍是随钻测井继续发展的强劲动力。作为一种较新的测井方法,随钻测井技术仍有许多有待发展和完善的方面,尤其是数据传输技术、探测器性能、资料解释和评价等。

Logging While Drilling was born only 10 years later than wireline logging. However, the LWD technology grew very slow in its first 50 years because of the restriction of basic industry. In recent 20 years, the LWD technology has been evolving and maturing considerably, and has been able to provide all commensurate logs in wireline logging tool family, such as relatively completed while-drilling electric, acoustic and nuclear logging suits, and while-drilling Nuclear Magnetic Resonance （NMR） and while-drilling pressure logging. Currently, LWD has become one of the primary oilfield engineering service technologies, its amount of jobs and business revenue are increasing fast. In the foreseeable future, the need of petroleum exploration and production will keep on being the strong driving force of LWD technology development. As a progressing logging method, the LWD technology is developing and improving, especially in the aspects of telemetry, sensor, interpretation of data and formation evaluation.
