Wellhead photoelectric remote sensing self-controlled drip system and wellhead photoelectric remote sensing self-controlled drip method

Abstract

The invention relates to a wellhead photoelectric remote sensing self-controlled infusion system and a wellhead photoelectric remote sensing self-controlled instillation method. The system includes the following parts: a tank body, used to store the medicament to be filled; a solenoid valve, used to quantitatively output from the tank body The medicament is filled; the control device is electrically connected with the above-mentioned parts, and is used for remote sensing and automatic control of the start and stop of the output of the solenoid valve, as well as the opening; the solar photovoltaic module is used for converting solar energy into electrical energy; The storage battery is used to store and output the electric energy from the solar photovoltaic module, so as to supply power to all parts of the system; wherein, the control device includes a temperature control module, which is used to control the temperature of the tank. The present invention integrates the above equipment, realizes timing, quantitative, automatic continuous and all-weather filling, unattended remote control, ensures the filling effect, and reduces the labor intensity and operating cost of workers.

Description

technical field [0001] The present invention relates to the fields of oil and gas well foam drainage and gas production, and oil and gas well methanol instillation, and specifically relates to a wellhead photoelectric remote sensing self-controlled drip system and a wellhead photoelectric remote sensing self-controlled drip method, which can be applied to remote wells in oil fields, especially grasslands, deserts, etc. It is used for automatic injection of foaming agent in oil (gas) and water wells in remote areas where power supply is difficult and unattended. Background technique [0002] At present, with the rapid development of domestic gas fields, problems in the exploration, development and production of gas wells are becoming more and more apparent, especially the problem of water outflow from production wells in gas fields. After water outflow from gas well formations, the production capacity of gas wells will be reduced, and the gas reservoir can be reduced. It incr...

AI Technical Summary

Problems solved by technology

Most domestic gas field single wells (especially remote wells) mainly use manual filling or filling vehicles for drainage and gas recovery, and mature automatic production equipment has not yet appeared. And big, if all low-yield wells are artificially injected with foaming agent every day, a very large professional service fleet will need to be formed, and there will be defects such as high manual labor intensity. At the same time, it will undoubtedly consume a lot of energy and produce a lot of exhaust gas emission

Obviously this is not in line with the concept of industrial automation and environmental protection
