Description

Technical Field

[0001] The utility model belongs to the technical field of process control equipment, in particular to a portable wireless online monitoring device for well washing. Background Art

[0002] Hot-washing oil wells primarily aims to improve daily well maintenance and management and extend the well pump inspection cycle. On-site hot-washing maintenance services are assigned by the production area's weekly hot-washing plan and temporary tasks. On-site supervisors are assigned to oversee the hot-washing process, managing the transition between wells and stations and adhering to operating procedures. The production area is required to maintain a record of temperature, current, and backflow, maintaining a single-well hot-washing log. The pre- and post-washing flushing times are adjusted based on actual field conditions to expedite drainage.

[0003] At present, there are many water well casing damages, which are often caused by the well washing switching process being operated too quickly and too violently, causing underground formation agitation, casing damage, and packer unsealing. This requires that the water well washing should be slow and steady when switching the process, but it is impossible to guarantee this by manually supervising the well washing process on site. Considering the situation of oil well washing and water injection well washing, it is urgent to develop a set of portable well washing monitoring equipment. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions: a portable wireless online monitoring device for well washing, including a base, a frame, a pipe, a jack, a lower bracket of a pipe clamp, a support plate, a universal wheel and an explosion-proof box. The base and the frame are fixed to form an L-shaped structure, the universal wheel is installed at the four corners of the bottom surface of the base, the bottom of the jack is fixedly installed on the base, the explosion-proof box is fixedly installed on the frame, the support plate is fixedly installed on the top of the jack, the lower bracket of the pipe clamp is fixedly installed on the support plate, the pipe is placed on the lower bracket of the pipe clamp, the lower bracket of the pipe clamp is screwed with an upper pipe clamp for clamping and fixing the pipe, and a threaded interface is provided on the pipe.

[0006] Preferably, a buffer rubber pad is fixedly provided in the top slot of the lower bracket of the pipe clamp.

[0007] Preferably, the explosion-proof box is fixedly provided with connecting blocks at the four corners, and the explosion-proof box is fixedly mounted on the frame by screwing the connecting blocks at the four corners.

[0008] Preferably, it further comprises a telescopic guide rod, wherein the upper and lower ends of the telescopic guide rod are fixedly connected to the supporting plate and the base respectively.

[0009] Compared with existing technologies, the advantages of this utility model are: this device is portable and mobile. The height of the pipeline can be easily adjusted using a jack to facilitate the connection of both ends of the pipeline to the well-washing pipe and the quick-connect interface. Pressure transmitters and temperature transmitters are installed at the threaded interface of the pipeline. The ultrasonic flowmeter probe is installed on the pipeline. The instrument online data is transmitted to the intelligent ARM development board inside the explosion-proof box via the 485 communication protocol. If the operation does not follow the operating procedures, the data can be transmitted remotely to the technical management personnel or technical center in the operation area, realizing remote monitoring, automatic alarm and real-time query. It enables one person to monitor multiple wells, and through automation and intelligentization, the well-washing quality of oil wells and water injection wells in the operation area is improved with stricter control.
