摘要
在欠平衡测井环境和条件下,如何保证安全、环保、高效地完成测井任务,成为测井面临的首要难题。所介绍的欠平衡测井防喷装置系统主要由法兰盘、电缆封井器、防落器、大直径防喷管、电缆控制头等组成,在该系统下建立了一套欠平衡测井施工步骤。经对多口井的欠平衡测井施工证明,利用该欠平衡系统能够获得合格的测井资料,取得了较好的应用效果。
Under the condition of underbalance well drilling,how to guarantee well logging in safe,environmental and high efficient way was difficult in well logging.The given BOP device for under balance drilling was composed of flange,cable seal device,anti-dropout device,big diameter lubricator and cable control head.A set of procedures were set up for the under balance drilling.It is used in many wells and acceptable data are obtained,better results are achieved.
