Deployment and retrieval of a data memory module in a well pipe
暂无分享,去创建一个
A memory tool deployment method includes fitting a landing ring on a pipe and deploying the pipe in a well. The memory tool 150 is connected to a wireline 102 and deployed through the pipe. The memory tool is landed on the landing ring 62 of the pipe 40 before being released from the wireline. The wireline is then removed from the well 20. Preferably, the wireline is redeployed to retrieve the memory tool when appropriate. The memory tool may be part of a tool string 120 including a drop-off tool 110. In an alternative aspect, the tool string has a landing collar 112 engageable with the landing ring and a coupling mechanism 104 is attached to the wireline. In a further aspect, a memory tool deployment system has means for engaging a landing ring of a pipe to support a memory tool from an end of the pipe.
