Problems solved by technology

Through the real-time measurement, calculation, analysis, and decision-making of the gas state of the wellhead device, the measurement and control computer makes a decision instruction set to control the gas injection state of the gas injection well side equipment, so as to obtain the combustion and gasification state in the deep coalbed gasification furnace cavity, and Solve the problems in the related technology that the controllable combustion and controllable gasification state of underground coal gasification cannot be controlled, that is, the gas state inversion on the gas production side is used to predict and control the injection parameters on the gas injection side to realize the control of the underground gasification furnace chamber. Internal Coal Combustion Gasification Control

Abstract

The present invention provides a measurement and control method and device for measurement and control of well -measured well estuary device, management exchange, and deep coal gasification. Among them, deep coal gasification measurement methods, including the following steps: step S10: collecting the air -harvesting of the air outlet device of the measurement and control wellThe water content, sulfur content, dust rate, gas component, temperature and pressure of the gas in the inside, and transmitted to the computer measurement and control computer, the measurement and control computer on the water content value, the value value value, the dust rate value, the gas group value, the temperature of the gas group, the temperature of the temperature, the temperatureThe values and pressure values are calculated, analyzed, and decided to generate a collection and control instruction set, sending the measurement and control instruction set to the boiler controller, the tube exchange controller, and the double -layer continuous pipe controller.The technical solution of this application effectively solves the problem of controlling controlling the controlled combustion and controllable gasification state of underground coal gasification in related technologies.

Description

technical field [0001] The invention relates to the technical field of underground coal gasification coal mining, in particular to a measurement and control wellhead device, a manifold, and a measurement and control method and device for deep coal gasification. Background technique [0002] The theory of underground coal gasification has been studied for a hundred years, especially after the introduction of the controllable withdrawal continuous gas injection process (CRIP) in the past 50 years. It has been proved that the underground gasification of CRIP is a mature continuous gas. However, 50 years of research has not formed a complete set of process technology methods and complete sets of technical equipment similar to oil and gas field development. In the past, the wellhead device of the oil and gas field was directly installed on the wellhead of the underground coal gasification coal mining, which could only serve the purpose of wellhead sealing, wellhead gas production...
