All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Example 1

The invention provides a logging conveying device, as shown in fig. 1-3, comprising: a plurality of serially arranged conveyance pipes 10, at least one connection mechanism 20, and a sleeve 50 for receiving a tool 60; the adjacent two conveying pipes 10 are connected through a connecting mechanism 20, and a sleeve 50 is connected to the lower ends of the conveying pipes 10; the two adjacent conveying pipes 10 comprise a first conveying pipe 11 and a second conveying pipe 12, and a connecting mechanism 20 is connected to the end part of the first conveying pipe 11; the first side 121 of the end of the second delivery pipe 12 is hinged to the connection mechanism 20, and the second side 122 of the end of the second delivery pipe 12 is connected to the connection mechanism 20 by the connection rope 21.

The logging conveying device is arranged in a well, a connecting mechanism 20 connects a first conveying pipe 11 and a second conveying pipe 12 together, the second conveying pipe 12 and the connecting mechanism 20 can rotate around a hinge shaft, and a connecting rope 21 limits the rotation range between the second conveying pipe 12 and the connecting mechanism 20; under the action of the connecting mechanism 20, the first conveying pipe 11 and the second conveying pipe 12 can rotate relatively, so that the logging conveying device can bend along with the shape of the well when moving downwards in the well, and the shape can be adjusted, thus, the obstruction of the movement of the logging conveying device in the well is reduced, and the logging conveying device can move downwards conveniently. When the logging tool 60 is conveyed using the logging conveyance, the logging conveyance may be driven down the well by striking the top of the logging conveyance at the wellhead. Therefore, the conveying equipment can be simplified, the operation difficulty is reduced, and the technical problems of huge conveying equipment, high operation difficulty and high cost existing in logging in the prior art are solved.

The end surfaces of the first conveying pipe 11 and the second conveying pipe 12 may be circular, and a hinge shaft between the end of the second conveying pipe 12 and the connection mechanism 20 may be provided along a tangential direction of the end surfaces of the second conveying pipe 12. Specifically, as shown in fig. 2, 3 and 5, the second side 122 of the end of the second conveying pipe 12 is provided with a hinge post 22, the hinge post 22 is provided with a hinge hole 221, the connection mechanism 20 is provided with a hinge shaft penetrating through the hinge hole 221, and the second conveying pipe 12 can rotate around the hinge shaft relative to the connection mechanism 20; as shown in fig. 2, the hinge hole 221 and the hinge shaft may be provided in a tangential direction of the end surface of the second conveying pipe 12. In the case where the logging conveying apparatus comprises a plurality of connection mechanisms 20, it is preferable that the hinge holes 221 in the respective connection mechanisms 20 are arranged in parallel.
