For solving the problems of the technologies described above, the utility model provides a kind of logger crossover sub, it is characterized in that, comprise joint body, described joint body one end arranges the first syndeton coordinating with ELIS logger, the described joint body other end is provided with the second syndeton coordinating with Halliburton DITS logger, and described joint body inside arranges the heart yearn that connects described the first syndeton, the second syndeton;
Described the first syndeton is external thread structure, and described the second syndeton is for arranging female inserting groove structure.
Above-mentioned logger crossover sub also can have following features, and described the first syndeton is provided with seal groove.
Above-mentioned logger crossover sub also can have following features, the inserting groove that described inserting groove is dark 10cm-20cm.
Above-mentioned logger crossover sub also can have following features, and described joint body is provided with installing hole near described the second syndeton place.
Above-mentioned logger crossover sub also can have following features, and described installing hole comprises 4 installing holes that are circumferentially distributed on described joint body outside.
Above-mentioned logger crossover sub also can have following features, and described joint body is titanium steel alloy-junction body.
The utility model technique scheme has following beneficial effect:
The technique scheme that the utility model provides specifically comprises joint body, joint body one end arranges the first syndeton coordinating with ELIS logger, the joint body other end is provided with the second syndeton coordinating with Halliburton DITS logger, and joint body inside arranges the heart yearn that connects the first syndeton, the second syndeton; The first syndeton is external thread structure, and the second syndeton is inserting groove structure.Change by preferred pipe nipple by technique scheme, can realize the serial downhole instrument of ELIS ERMT tension nipple and Halliburton DITS and articulate use, and reliable tension force, temperature signal are provided; Can realize the collection signal transmission between ELIS logging system and Halliburton DITS logging system.
Further, in the utility model concrete operations, joint body can adopt titanium steel alloy-junction body; Can effectively improve the stability that the utility model connects, can effectively improve application life of the present utility model.
Other features and advantages of the utility model will be set forth in the following description, and, partly from manual, become apparent, or understand by implementing the utility model.The purpose of this utility model and other advantages can be realized and be obtained by specifically noted structure in manual, claims and accompanying drawing.
Accompanying drawing explanation
