Description

Technical Field

[0001] This invention relates to the field of well pipe installation technology, and more specifically to an automated well pipe installation device. Background Technology

[0002] In surface drilling, well casing needs to be installed in the borehole to maintain its unobstructed flow and stability. Well casing, also known as wellwall casing, refers to the casing that protects the well wall; sometimes it also refers to casing or filter pipe. It can be made of steel pipe, cast iron pipe, cement asbestos pipe, cement gravel pipe, ceramic pipe, slag pipe, plastic pipe, fiberglass pipe, etc. These materials generally result in large volume and weight, making their installation relatively difficult. In existing well casing installation methods, holes are first drilled on the ground, and then several well casings are sequentially lowered into the holes using manual manipulation. The casings are then joined together in the holes until they reach the wellhead. This installation method has the following drawbacks:

[0003] 1. Manual installation requires a large workforce and is inefficient.

[0004] 2. During the process of inserting the well pipe into the hole, it is impossible to know the depth of the well pipe into the hole, and it is impossible to accurately control the vertical and horizontal position of the well pipe in the hole. It is also impossible to ensure that the connection between adjacent well pipes is tight and precise enough, which makes it easy for soil, gravel and other materials around the well pipe to squeeze into the well through the gaps between the well pipes, which can easily cause collapse accidents or pollute the water source. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an automated well casing installation device that saves manpower and improves the accuracy, reliability and efficiency of well casing installation.

The electrical control device 9 is electrically connected to the hoisting mechanism 6, the conveying mechanism 3, the positioning mechanism 4 and the fine-tuning mechanism 5, respectively, and is used to centrally monitor and control the entire automated well casing installation equipment.

[0035] In this embodiment, preferably, such as Figure 6 As shown, the automated well casing installation equipment also includes a binding device 7 and a winding device 8. The binding device 7 and the winding device 8 are fixed sequentially from bottom to top on the side of the hoisting mechanism 6. An electrical control device 9 is electrically connected to both the binding device 7 and the winding device 8 to monitor and control them. The binding device 7 can be an automatic packaging machine, or a device with a similar structure and function, used for binding the wire mesh. The winding device 8 can be a wrapping machine, or a device with a similar structure and function, used for wrapping the wire mesh on the surface of the well casing.

[0036] In this embodiment, preferably, such as Figure 2 As shown, the automated well casing installation equipment also includes a traveling mechanism 2. An electrical control device 9 is electrically connected to the traveling mechanism 2 to enable the automated well casing installation equipment to move automatically.

Specifically, the motor 201 is fixedly connected to the lower surface of the base 1, and the drive shaft 204 is fixedly connected to the lower surface of the base 1 via bearings.

[0037] In this embodiment, preferably, such as Figure 1 and Figure 7 As shown, the automated well casing installation equipment also includes a balancing mechanism 10. The electrical control device 9 is electrically connected to the balancing mechanism 10. The balancing mechanism 10 includes several hydraulic cylinders evenly fixed at the front and rear ends of the base 1. The output shaft of the hydraulic cylinder is fixedly connected to an adjusting block, and the output shaft extends and retracts in the direction of the ground. When the adjusting block abuts against the ground, it can lift the corresponding part of the automated well casing installation equipment. Thus, the multiple hydraulic cylinders cooperate to adjust the base 1 to achieve a balanced state, thereby achieving the purpose of adjustment and ensuring the normal operation of the equipment.

[0038] Working principle: After drilling the well, the automated well pipe installation equipment is centrally controlled by the electrical control device 9 to achieve various functions. The automated well pipe installation equipment travels to the location where the well needs to be installed via the walking mechanism 2, and the balancing mechanism 10 adjusts the device to a horizontal state. The conveying mechanism 3 conveys the well pipe to be installed to the front of the positioning mechanism 4. The infrared sensor 306 can determine the position of the well pipe on the conveying mechanism 3, causing the well pipe to stop at the preset position and queue up the well pipes. The well bottom is installed on the upper surface of the fine-tuning mechanism 5, and the clamping feeder 403 clamps the well pipe and moves it. Upon reaching the second adjustment platform 505, adjustments are made via the fine-tuning platform to ensure the well pipe is installed to the bottom of the well. The hoisting sling 605 passes through the bottom of the well, and the hoisting mechanism 6 is activated, rotating and positioned above the well hole. The hoisting sling 605 is then lowered, causing the well pipe to descend. The winding device 8 is activated, wrapping wire mesh around the surface of the well pipe. The binding device 7 is activated, binding the well pipe in sections, binding it at the bottom center and top of the well. This process of lowering, winding, and binding continues until the well pipe is placed into the well hole. This process is repeated for the second, third, and so on, until the installation is complete. During the lowering process, the meter 606 senses the descent distance and uses the recorded descent distance of the previous well pipe to determine the descent distance of the next well pipe, thus precisely controlling the descent distance of each pipe and ensuring a tight connection between the well pipes.

[0039] The above description is a detailed description of the preferred embodiments of the present invention. However, the embodiments are not intended to limit the scope of the patent application of the present invention. All equivalent changes or modifications made under the technical spirit of the present invention should fall within the patent scope covered by the present invention.
