Intelligent control device and method for water well testing and regulating

Abstract

The invention relates to an intelligent control device and method for water well testing and regulating. The intelligent control device mainly comprises a vehicle-mounted fixing frame, a sliding mechanism and a well head locator, wherein the vehicle-mounted fixing frame is mounted aside a well head, the well head locator is mounted on a water injection well head, the well head locator and the water injection well head are connected through a conveying steel cable, a traction rope is fixed on the sliding mechanism, the sliding mechanism is conveyed to the well head and is located by the well head locator, a blowout prevention pipe is erected through a blowout prevention pipe carriage and tumbler, is aligned with the water injection well head to be tested and is fixed on the water injection well head by an automatic clamping stirrup, a well head testing valve is automatically opened by using an automatic valve opening device at the water injection well head, and then, a tester in the blowout prevention pipe can freely carry out rising and falling operation. The device and the method have the beneficial effects that heavy physical work for personnel is reduced, and the blowout prevention pipe can be transported and mounted by using the control device instead of workers, so that the number of laborers employed is reduced, potential safety hazards are reduced, and the safety of enterprises is improved.

Description

technical field [0001] The invention relates to a petroleum industry equipment and method, in particular to an intelligent control device and method for water well surveying and adjusting. Background technique [0002] In the middle and late stages of oilfield development, with the reduction of formation energy, it is more and more difficult to extract crude oil, especially for low-permeability oil reservoirs, because the permeability of the oil layer is extremely low, the crude oil near the oil well cannot effectively penetrate into the oil well, this It is necessary to take a series of technological measures to increase the permeability, or carry out water flooding to increase the energy of the formation. Therefore, as an important measure to increase production, water injection is accompanied by the entire crude oil production process, and the quality of water injection directly affects the oil recovery efficiency and the overall development level. [0003] In the water ...

Problems solved by technology

When testing and deploying, it is necessary to lower the test instruments and special deployment tools to the underground through the test and adjustment steel wire cable. The current operation is done manually. Install the test tools, install the wellhead blowout preventer, the wellhead valve switch, and lower the test tools. Manually The operation steps are relatively complicated. A team needs at least 3 operators, and the labor intensity is relatively high. The main problems are as follows: 1. The physical labor of the workers is heavy, and there are many operators.

2. There are many safety hazards in the manual operation process: when the instrument is blocked when going down the well, the operator needs to climb up the 2-meter-high blowout pipe to adjust the cable, and there are great safety hazards in snowy, rainy and windy days; in addition, manual Open the wellhead test valve. For the wellhead pressure of 10-25 MPa, manual operation also has great unsafe factors
