Problems solved by technology

[0003] In order to solve the technical problems mentioned in the background technology, the present invention provides an intelligent downhole measurement and adjustment tool. With this tool, all the measurement and adjustment work can be completed once downhole, which simplifies the operation process, and the instrument can also be raised manually. The adjusting arm is retracted into the card arm compartment, avoiding the situation of being stuck with the water distributor and unable to move

Embodiment Construction

[0042] The present invention will be further described below in conjunction with accompanying drawing:

[0043] This kind of downhole intelligent measurement and adjustment tool includes: cable joint 2 and internal two-core joint 3, upper connection plug 4, shell 5 and internal circuit board 7, circuit board mounting frame 6, motor 11, motor housing 9, Main devices such as copper shaft coupling 10, mandrel 12, card arm storehouse 14 and internal left arm device 20, right arm device 21, cam 13, non-metal core 28 below, non-metal head 29, coil 27.

[0044] exist figure 1 Among them, the upper end of the cable connector 2 is serrated, so that the outer layer of the cable wire is fixed on the upper end of the cable connector 2 to prevent sliding and falling off, so that the cable wire penetrates into the center hole 203 of the cable connector and is connected with the two-core connector 3 below. The lower end of the cylindrical hole 202 in the cable joint is threaded together wit...

Abstract

The invention discloses an underground intelligent measuring and adjusting tool. The tool comprises a cable joint, a two-core joint, an upper connecting plug, a circuit board at the lower part, a mounting frame of the circuit board, a shell, a motor, a motor shell, a copper coupling, a clamping arm bin, an internal adjusting arm device, a nonmetal core at the lower part, a nonmetal head and an electric coil, wherein the circuit board sends data to a ground control system through a cable, and meanwhile a ground controller sends different control commands to the circuit board to control the tool. The measuring and adjusting tool can work up and down repeatedly under a well, and complete all measuring and adjusting work once under the well, so the operation process is simplified, the workingtime of measuring the well is shortened, the measuring and adjusting efficiency and success rate are improved, and the labor intensity of workers is alleviated and the working time is shortened.

Description

technical field [0001] The invention relates to a downhole measurement and adjustment tool used in the technical field of oil field logging. Background technique [0002] Water flooding technology is a method to increase the oil production of oil wells. By injecting water into the oil layer to increase the pressure in the oil layer, the oil production of the oil well will increase. At present, the seal inspection and adjustment of concentric water injection wells need to use the seal tester and There are two types of instruments for testing and adjustment, and seal inspection and adjustment need to be performed twice, that is, two downhole tests are required to complete the seal inspection and adjustment work, and each layer needs to be injected with water and the situation of each oil layer is different. Sealing inspection and testing and adjustment operations are performed on each floor. Such complicated operations reduce work efficiency, increase construction costs and wo...
