随钻测井在滩海区大位移定向井中的应用

Application of LWD to ERD well in Shallow Water Area.

随钻测井技术是近年来发展起来的一项新的测井技术 ,其主要特点是边钻边测 ,在完成钻井任务的同时完成测井任务。解决了电缆测井无法施工的高难度井的测井问题 ;对随钻测井在高难度井的应用进行了分析 ,并与电缆 (钻杆输送 )测井进行对比 ,阐明了随钻测井的特点和应用环境 。

LWD(logging while drilling) is a new logging technology developed in recent years, its main charateristic is logging can be run while drilling. It is a good solution for ERD (extended reach drilling) well logging when it is hard to use wireline well logging. The application of LWD in ERD well is analyzed and compared with wireline (i.e. drill pipe convey) logging. The comparison indicates that LWD is a best choice in ERD wireline well logging. And LWD advantages as well as its application environments are described.
