Integrated intelligent well control system for geothermal hot spring well

Abstract

The invention provides an integrated intelligent well control system for a geothermal hot spring well. The system comprises a distribution box, an underground device and a wellhead device, a touch screen is arranged on a box body of the distribution box, a PLC electrically connected with the touch screen is arranged in the box body, and the PLC is connected with a remote upper computer. The underground device comprises a deep-well pump, a temperature detector is installed on the surface of a pump body of the deep-well pump, and a high-temperature liquid level sensor is installed above the pumpbody of the deep-well pump. The wellhead device comprises a well base, the upper end of the well base is connected with a second three-way pipe through a pressure reducing valve, a first three-way pipe and a first worm gear manual butterfly valve, a first output opening of the second three-way pipe is connected with a detection assembly for detecting the temperature, oxidation-reduction potential, PH value, H2S and harmful gas of hot spring raw water, a second output opening is connected with a third three-way pipe through a main straight-through pipe, an electric butterfly valve, a flow monitor and a second worm gear manual butterfly valve are installed on the main straight-through pipe, and a detection instrument is electrically connected with the PLC. The system can detect hot spring water and transmit signals in real time and can control a hot spring pipe network.

Description

technical field [0001] The invention relates to the technical field of geothermal hot spring control, in particular to an integrated intelligent well control system for geothermal hot spring wells. Background technique [0002] Geothermal hot springs refer to hot springs that use water as a medium to bring heat from underground to the surface. Geothermal heat is natural heat energy that comes from the deep part of the earth's crust and is stored in rocks and rock pores and cracks. The main body of development and utilization is geothermal fluid that integrates heat, minerals, and water. It is a very valuable clean energy source. Hot springs are natural outcrops of geothermal heat, and are important geological relics with protection, utilization and ornamental value. my country is a country dominated by medium and low temperature geothermal resources. The development and utilization of medium and low temperature geothermal hot springs are directly used for heating, heating, ...

AI Technical Summary

Problems solved by technology

[0004] In view of the fact that the existing hot spring well installation equipment is installed independently by a single equipment and does not form a complete set of equipment. In the actual application process, there are technical problems such as inconvenient installation, single function, low degree of intelligence and incapable of remote control. The present invention provides a Integrated intelligent well control system for geothermal hot spring wells
