Description

Technical Field

[0001] The utility model belongs to the technical field of well completion tools, in particular to a well completion tool open hole packer rubber cylinder compression testing machine. Background Art

[0002] An open-hole packer is a differential pressure-sealed, injection-type packer ideal for stratified separation within the casing or open-hole section of an oil and gas well. The open-hole packer's rubber cartridge deforms under compression, aligning with the wellbore to achieve stratified separation. Current compression and reset testing of the open-hole packer's rubber cartridge presents significant challenges in loading and unloading due to the heavy weight of the open-hole packer assembly. This requires the use of a large robot to lift the assembly, resulting in high testing costs. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a well completion tool open hole packer rubber cylinder compression testing machine with convenient loading and unloading.

[0004] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: A completion tool open hole packer rubber cylinder compression testing machine, including a tooling table, a base, an electric push rod, a guide sleeve, a wheel seat, a support wheel, a hydraulic cylinder, a pressure plate, a limit seat and a bearing seat. The tooling table is fixedly installed on the base, the electric push rod is fixedly installed on the base, the limit seat and the bearing seat are respectively fixedly installed on the left and right ends of the tooling table surface, the guide sleeve is fixedly installed on the tooling table, the wheel seat is slidably installed on the guide sleeve, the lower end of the wheel seat is fixedly connected to the actuator rod of the electric push rod, the two support wheels are symmetrical and fixedly installed on the left and right sides of the top surface of the wheel seat, the cylinder body of the hydraulic cylinder is fixedly installed on the bearing seat, the pressure plate is fixedly installed on the piston rod of the hydraulic cylinder, and a forklift groove is provided on the inner side of the tooling table surface.

[0005] Preferably, four guide rods are fixedly mounted on the pressure plate in a rectangular distribution, and the guide rods are slidably mounted on the bearing seat.

[0006] Preferably, the top surface of the support wheel is an arc surface structure.

[0007] Preferably, a scale ruler is provided on the table top of the tooling table.

[0008] Compared with the existing technology, the benefits of the present invention are: this testing machine can use a forklift to carry out the loading and unloading operations on the open hole packer body on the workbench. After loading to the workbench, the open hole packer body is rolled to the position between the two support wheels, which has the advantage of convenient loading and unloading. At the same time, the cost of using the loading and unloading tools is low. When the rubber cylinder is tested, the open hole packer body can slide left and right between the support wheels, which can meet the requirements of the detection test and avoid sliding wear on the surface of the open hole packer body. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The present invention will be further described below with reference to the accompanying drawings.

[0010] Figure 1 It is the main view of the present utility model.

[0011] Figure 2 It is a top view of the present utility model. DETAILED DESCRIPTION

[0012] The present invention is described in detail below in conjunction with specific embodiments:

[0013] like Figure 1 and Figure 2 The shown method is to use a completion tool open hole packer rubber cylinder compression testing machine, which includes a tooling platform 1, a base 2, an electric push rod 3, a guide sleeve 4, a wheel seat 5, a support wheel 6, a hydraulic cylinder 7, a pressure plate 8, a limit seat 11 and a bearing seat 12. The tooling platform 1 is fixedly mounted on the base 2, the electric push rod 3 is fixedly mounted on the base 2, the limit seat 11 and the bearing seat 12 are respectively fixedly mounted on the left and right ends of the table top of the tooling platform 1, the guide sleeve 4 is fixedly mounted on the tooling platform 1, the wheel seat 5 is slidably mounted on the guide sleeve 4, the lower end of the wheel seat 5 is fixedly connected to the actuator rod of the electric push rod 3, the two support wheels 6 are symmetrical and fixedly mounted on the left and right sides of the top surface of the wheel seat 5, the cylinder body of the hydraulic cylinder 7 is fixedly mounted on the bearing seat 12, the pressure plate 8 is fixedly mounted on the piston rod of the hydraulic cylinder 7, and a forklift groove 13 is provided on the inner side of the table top of the tooling platform 1, which can enable the fork claws of the forklift to be embedded in the forklift groove 13 to realize loading and unloading using a forklift.

[0014] Four guide rods 81 are fixedly installed on the pressure plate 8 in a rectangular distribution. The guide rods 81 are slidably installed on the bearing seat 12. Through the guiding effect of the guide rods 81, the straightness of the pressure plate 8 when it moves left and right can be improved, avoiding the problem of tilting when the pressure plate 8 contacts the right end of the open hole packer 10.

[0015] The top surface of the support wheels 6 is an arc surface structure, so that the open hole packer 10 can be embedded between the two support wheels 6.
