Problems solved by technology
[0003] Nowadays, more and more attention is paid to the safety performance of the wellhead, but it is generally emphasized that employees carry out safe and standardized operations, and manually detect whether there is flame generation, whether there is any flammable gas leakage, whether there is leakage in the oil and gas pipeline, and the temperature and humidity of the wellhead. The hidden danger is relatively large, and it is easy to cause property loss, and the manual detection part depends on the experience of the staff, and the accuracy needs to be improved. Therefore, an intelligent control device and control system for intermittent wells is needed

The invention discloses an intermittent well intelligent control device and control system. The intermittent well intelligent control device comprises connecting pipes, the number of the connecting pipes is three, the connecting pipes are an oil inlet pipe, an oil conveying pipe and an oil conveying pipe in sequence from bottom to top, an adjusting mechanism is arranged between the oil inlet pipe and the oil conveying pipe, an adjusting module is arranged between the oil conveying pipe and the oil conveying pipe, the adjusting module comprises a oil extraction pump, the input end of the oil extraction pump communicates with the oil conveying pipe, the output end of the oil extraction pump communicates with the oil conveying pipe, and a power converter and a signal receiving module are arranged on one side of the oil extraction pump and electrically connected to the oil extraction pump. According to the intermittent well intelligent control device and control system, due to arrangement of a second oil way and a conical groove, full-time load operation of the oil extraction pump is achieved, equipment abrasion and idling operation caused by oil well intermittence are avoided, a detector is arranged to complete crude oil analysis and water content detection, a metering separator is arranged to monitor the gas-liquid proportion of crude oil, a first oil way or the second oil way is selected for oil extraction through analysis of a main controller, and equipment damage caused by the oil well intermittence is avoided.
Description
technical field [0001] The invention relates to the technical field of intermittent well control, in particular to an intelligent control device and control system for intermittent wells. Background technique [0002] An oil well is a hole drilled by drilling methods. Generally, when an oil well reaches a layer thickness, it is lowered into an oil layer casing, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas, and According to the requirements of oilfield development, perforating guns are used to open the oil layer to form a channel, which is lowered into the oil pipe, and the oil is raised from the bottom of the oil well to the head of the well with a suitable induction method. [0003] Nowadays, more and more attention is paid to the safety performance of the wellhead, but it is generally emphasized that employees carry out safe and standardized operations, and manually detect whethe...
