东海平湖BG-2井井口回接的实践与认识

The Practice and Recognition of Location of BOP at PingHu BG-2 Well

平湖BG - 2井是一口重钻井 ,其原井口的永久导向架已被回收 ,无法使用用于回接导向绳的回接器 ,所以本井防喷器如何回接就位就成了首先要解决的问题。文章分析防喷器就位回接时存在的风险 ,详细地介绍了防喷器就位的全过程 ,及对在就位过程中使用到的钻具组合的作用进行分析和说明。本井防喷器成功就位为半潜式平台无导向绳井口回接提供借鉴 ,同时还可从中汲取经验和教训。

The well PingHu BG-2 is a re-drilled well, its permanent guide frame had been retrieved, and the remote connector of the guide rope cannot be used, so how to make the BOP located became a problem that must be done with above all. The paper not only analyzes the adventure exist in the location of the BOP, and introduces the whole process in detail, but also analyzes and explains the function of drilling tool assembly used in the process. The experience of BOP located successfully provides good reference for the BOP location without the guide ropes on the semi-submarine drilling platform. At the same time we can draw some experience and lessons from the paper.
