Problems solved by technology

For long-term production wells, due to various reasons, the inner diameter of the casing shrinks and deforms, resulting in the failure of the drift gauge to pass normally, and the lack of responsibility of the on-site operators will cause quality accidents of stuck pipe
This kind of pipe sticking quality accident causes great losses to the downhole construction, and it takes a lot of time and effort to deal with it, which increases the workover cost

specific Embodiment approach

[0016] combine figure 1 and figure 2 , the intelligent diameter gauge includes a cylindrical body 1 with one end open, an upper joint 4 is provided at the closed end of the body 1, and a cylindrical guide head 2 with two open ends connected to the open end of the body 1 through a central tube 3, the guide head 2 There is a dovetail groove 8 on the inner wall, and a fixed block 7 is fixed in the dovetail groove 8. A cylindrical grit chamber 6 with one end open is arranged on the fixed block 7. The opening direction of the grit chamber 6 is in the same direction as the guide head 2. 6 Make the smart gauge itself have the function of a sedimentation cup to avoid the accident of falling objects stuck. The back side of the grit chamber 6 is equipped with an intelligent probe 5, which is used to detect the oil field downhole pipeline situation.

[0017] The main body 1, the guide head 2, and the upper joint 4 are all made of stainless steel, which is durable and has good corrosio...

Abstract

The invention relating to the field of oil well equipment discloses an intelligent drift diameter gauge. The existing drift diameter gauge is designed to be a split equal-diameter deformable drift diameter gauge, so that a drilling clamp accident caused by the deformation and diameter reduction of the casing pipe is avoided. In the prior art, the existing cylinder has an enclosed top end and the open bottom; and according to the intelligent drift diameter gauge, the cylinder has an open top end and an enclosed bottom end, so that the tool has the sedimentation cup function, so that the drilling clamping accident caused by the fallen object is avoided. A phenomenon that the drilling is stuck in the drilling work due to fallen object accumulation and deformation and diameter reduction of thecasing pipe during the working process is avoided. The risk quality accident of the well repairing and ventilation procedure for underground work is reduced; and the construction efficiency of the well operation is improved.

Description

technical field [0001] The invention relates to the field of oil well equipment, in particular to an intelligent drift gauge. Background technique [0002] In oil, gas and water well workover operations, well drilling is an essential process. In the early stage, the top and bottom outer diameters of the diameter gauges used were equal. For long-term production wells, due to various reasons, the internal diameter of the casing shrinks and deforms, resulting in the failure of the drift gauge to pass normally, and the lack of responsibility of the on-site operators will cause quality accidents of stuck pipe. This stuck pipe quality accident causes greater losses to the downhole construction, and it takes a lot of time and effort to deal with it, increasing the workover cost. Therefore, this intelligent drift gauge is designed, and the existing drift gauge is designed into separate equal-diameter and deformable drift gauges, so as to avoid pipe sticking accidents caused by cas...
