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 invention provides a measurement and control wellhead device, a manifold, a measurement and control method for deep coal gasification and a device thereof.The measurement and control method for deep coal gasification comprises the following steps that S10, the water content, the sulfur content, the dust rate, the coal gas components, the temperature and the pressure of coal gas in a gas production wellhead device of the measurement and control wellhead device are collected; the water content value, the sulfur content value, the dust rate value, the gas component value, the temperature value and the pressure value are calculated, analyzed and decided by the measurement and control computer to generate a measurement and control instruction set, and the measurement and control instruction set is sent to the boiler controller, the manifold controller and the double-layer continuous pipe controller. According to the technical scheme, the problems that in the related technology, controllable combustion of underground coal gasification and control over the controllable gasification state cannot be achieved are effectively solved.

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 nearly fifty years of continuous gas injection with controllable withdrawal (CRIP). 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 devices of oil and gas fields were directly installed on the wellheads of underground coal gasification coal mining, which could only serve the purpose of wellhead sealing, wellhead gas recovery and flow measurement. [0003] ...
