Abstract

The invention relates to an underground matched tool for coiled tubing drilling, in particular to a measurement while drilling tool for coiled tubing drilling. The lower end of a sleeve of the tool is in threaded connection with a positioning connector and sealed through a sealing ring, a cable enters the sleeve, and a cable core at the lower end of the cable is connected with a copper pillar through a fixing screw; the lower end of the copper pillar is connected with a circuit board through a switching connector I; and the cable is sleeved with a cable switching connector framework, and the lower end of the cable switching connector framework is connected with an insulating sleeve through screws. The measurement while drilling tool can collect downhole parameters such as well deviation, directions, tool faces and magnetic field strength in real time in the coiled tubing oriented drilling process, the tool can be controlled on the ground through a computer simply, conveniently and reliably, and the drilling directions and well tracks of sidetracked wells, sidetrack horizontal wells, directional wells and other wells drilled through coiled tubing drilling can be monitored more precisely and reliably; and the measurement while drilling tool has the advantages of high real-time performance, high response speed and good reliability, and provides basis for track control in directional drilling.

Description

Technical field: [0001] The invention relates to a coiled tubing drilling downhole supporting tool, in particular to a coiled tubing drilling measurement tool. Background technique: [0002] While drilling technology is commonly used in drilling engineering, it is widely used in directional wells, horizontal wells and sidetracking horizontal wells, etc., commonly used in two types: wired while drilling and wireless while drilling. [0003] Coiled tubing drilling is a drilling technology developed in recent years. The use of coiled tubing equipment for drilling construction is different from conventional drilling. Coiled tubing drilling requires supporting special downhole tools. The application of coiled tubing drilling technology in coiled tubing drilling is also divided into wired while drilling. Similar to wireless while drilling, wireless while drilling is basically the same as that used in conventional drilling. Wired while drilling needs to package the sensor in the to...
