Description
Technical field
The utility model relates to a kind of modularization coiled tubing Wellhead Control Systems for coal underground gasifying technology, belong to
In coal underground gasifying technology equipment technical field.
Background technique
Underground coal gasification(UCG) (ISC) is one by oxidant, and burning and gasification reaction by subterranean coal are straight coal
Switch through the process for turning to product gas.Product gas is commonly known as synthesis gas, can be used as fuel production, Chemical Manufacture, power generation etc.
The raw material of downstream process.The technical process the set complete well of shaft building, underground coal mining and coal gasification process technology have safety
Well, the advantages that investing small, high efficiency, pollution less.
One drilling well for oxidant injection is known as " injection well ", another drilling well for being used to produce product gas is known as
" product well ".Directed drilling and vertical drilling all can be used as injection well or product well.Underground coal gasification(UCG) (ISC) may inject
It is also needed between well and product well using to one or more vertical well (such as: functional well and service well).
When having injection well, product well and horizontal channel to connect the two in coal seam, this construction is referred to as a coal
Charcoal underground gasification (ISC) unit or well pair.ISC unit includes combustion zone, gasification zone and pyrolysis zone.Wherein, combustion zone is in coal seam
Near middle oxidant decanting point；Gasification zone is centered around around combustion zone or in combustion zone downstream in the form of radial, and coal exists
Gasification zone is gasified, is partially oxidized, to generate product gas；Pyrolysis zone generally exists in gasification zone downstream, the pyrolytic reaction of coal
Here occur.The product gas of high temperature is finally transported to ground from product well well head from gasification zone toward downstream flow.In coal combustion
Or while gasification, the ISC burned out area in coal seam, which can be grown, to become larger.
Synthesis gas (CO, CO are usually contained by the product gas (crude synthesis gas) that underground coal gasification(UCG) generates2, H2, CH4And
The mixture of other gases) and other compositions (solid particle, water, coal tar, hydrocarbon vapours, other microcomponents include
