Measurement while drilling instruments include driver modules, battery modules, and directional probe modules. Due to the downhole working conditions and manufacturing processes, it is difficult to integrate the modules into one, so there are independent functional modules. Each functional module is assembled with a matching joint equipped with a centralizer and a pressure-resistant cylinder to form an instrument string for use in the well. During the use of the instrument, the assembly, disassembly, testing, and maintenance of each functional module are long-term problems faced by front-line operators.

[0015] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.
[0016] like Figure 1-3 As shown, the utility model provides a technical solution: a quick connection mechanism of a drilling measurement instrument, including a semicircular fixing ring 1, a matching joint 3 and a functional module 4, the number of the semicircular fixing rings 1 is two, the end of the functional module 4 close to the matching joint 3 is connected to a first electronic connector 7, the end of the matching joint 3 close to the functional module 4 is connected to a second electronic connector 8, and the first electronic connector 7 is connected to the second electronic connector 8.
[0017] By setting a semicircular fixing ring 1, the combination of two semicircular fixing rings 1 is used to shield and protect the connection between the functional module 4 and the mating connector 3 to prevent external debris and moisture from affecting the connection between the two; by setting a first electronic connector 7 and a second electronic connector 8, when the two are connected, an electrical connection between the mating connector 3 and the functional module 4 is achieved.
[0018] A groove is provided on the inner wall of the semicircular fixing ring 1, and at least one of the two end faces of the groove is set as a conical surface. The end face of the groove is a conical surface, so that the end heads can be squeezed and moved smoothly when the two semicircular fixing rings 1 are approached to each other.
[0019] The end parts of the functional module 4 and the mating joint 3 that are close to each other are adapted to the grooves, and the semicircular fixing ring 1, the mating joint 3 and the functional module 4 are provided with a pressure-resistant cylinder 5 outside. By setting the grooves, the grooves are used to cover and limit the ends of the functional module 4 and the mating joint 3, so that the ends of the functional module 4 and the mating joint 3 maintain stable contact in the grooves.
[0020] Two threaded holes and two countersunk holes are respectively provided at the four corners of the semicircular fixing ring 1. The two threaded holes and the two countersunk holes are arranged diagonally, and the threaded holes and the countersunk holes on the upper and lower sides are staggered. Fastening screws 2 are provided in the threaded holes and countersunk holes at corresponding positions. By setting the threaded holes, countersunk holes and fastening screws 2, the fastening screws 2 are threadedly connected to the threaded holes and the countersunk holes, which are used to connect the two semicircular fixing rings 1.
[0021] Two guide pins 6 are connected to the end of the mating joint 3 near the functional module 4, and a pin hole is opened at the end of the functional module 4 at the position corresponding to the guide pin 6. The guide pin 6 is arranged in the pin hole. By setting the guide pin 6 and the pin hole, the guide pin 6 cooperates with the pin hole to guide the assembly of the mating joint 3 and the functional module 4, and at the same time avoids the misalignment and rotation of the mating joint 3 and the functional module 4.
[0022] The working principle of the utility model is: directly align the mating connector 3 and the functional module 4, and insert the guide pin 6 into the corresponding pin hole. During the plugging process, the first electronic connector 7 is connected to the second electronic connector 8, and then the groove positions of the two semicircular fixing rings 1 correspond to the end parts of the mating connector 3 and the functional module 4, and then the two semicircular fixing rings 1 are fastened, and the fastening screws 2 are screwed into the countersunk holes and the threaded holes to achieve the connection and fixation of the mating connector 3 and the functional module 4.
