Description
Technical field
This practical new equipment belongs to natural gas line system for recovering waste water technical field, is specifically related to a kind of rock gas and produces pipeline hydrops recovering device, reclaim for the hydrops in natural gas line production process.
Background technique
In gas gathering and transportation process, collection gas transmission line is restriction production capacity, causes the major reason of potential safety hazard due to blocking that the reasons such as hydrate cause.Existing solution takes measure such as note alcohol or wellhead venting etc. to carry out de-plugging.
Note alcohol: refer to have a large amount of liquid waters to exist bottom gas well, these water exists too much, the normal production of rock gas can be affected, so when gas well liquid loading in summer, foaming water discharge agent can be added in well, by producing a large amount of bubbles, increase rock gas rise time take outlet capacity, a large amount of hydrops is discharged to outside well.And in the winter time, although do not carry out draining, due to evaporation and volatilization, have a large amount of water vapour equally and enter production flow line with natural gas flow, if do not added any measure, these water vapour one run into the low temperature of outside, can condense into solid rapidly, be formed as white crystal hydrate, be attached on the tube wall of gas transmission line, this behavior continues for some time, and just can increase gradually, so that last blocking pipe, causes the production work of rock gas to stop.The conveying of impact production and rock gas is brought for alleviating blockage problem, by theory analysis practice contrast, finally determine to select lower, the low price of freezing point, on rock gas and manufacturing mechanism because the less alcohols material of impact makes antifreezing solution, concrete, note alcohol is the generation in order to prevent hydrate, need with alchol-injection pump, methyl alcohol to be injected in pit shaft or flow line, to ensure normal production.But alchol-injection pump is in operation and there will be leakage phenomenon, not only severe contamination environment around, and waste resource.
Wellhead venting: there is certain pressure at the well head of gas field gas recovery well to metering station line sections, when well head needs repairing, the pressure existed in well head to metering station line sections will be bled off, this operation is called emptying at the scene.Due to this depot siding length at hundreds of rice to a few km, if at wellhead venting, the crude oil of outflow can pollute ground, and crude oil also can be caused to waste.In order to avoid polluting and crude oil waste, current employing tank pond is collected or igniting is burnt, it is that the crude oil flowed out during emptying is put into tank pond that tank pond is collected, again tank pond being retracted petrol station puts in accumulator tank, this way labor strength is large, inefficiency, still has part crude oil to land, and still there is certain pollution and crude oil waste; Igniting is burnt wastes resource then real genus.
Number of patent application is 201320463881.1 provide a kind of well mouth of oil well evacuating device, comprise flow tee, produce gate, well head four-way, upper flange, fuel-displaced gate, emptying gate, flow line, sleeve gate, upper flange is arranged on well head four-way, produce gate installation on upper flange, flow tee is arranged on to be produced on gate, fuel-displaced gate installation is on the side outlet of flow tee, sleeve gate is arranged in the lateral openings of well head four-way, flow line is connected with the outer end of fuel-displaced gate, flow line is installed emptying gate, the upper end of emptying flexible pipe is connected with emptying gate, the lower end of emptying flexible pipe is connected and fixed device, the clip connected of fixture and sleeve gate, when needing the pressure of emptying flow line, open emptying gate, the crude oil flowed out during well mouth of oil well emptying is placed in well, crude oil can not land, there is not pollution problem, also crude oil can not be wasted, simple to operate, convenient, labor strength is little, working efficiency is high.But this patent gas-liquid separation problem in unresolved rock gas, then when crude oil recovery being utilized, be also doped with a certain amount of gas, waste resource.
Number of patent application is 201320215525.8 provide Portable well head pipeline note alcohol device, and comprise housing, the top of housing is provided with and enters pipe and emptying valve, and the bottom of housing is provided with outlet pipe; Be characterised in that: enter on pipe and be provided with filling ball valve and funnel, outlet pipe being provided with note alcohol valve and short circuit, short circuit being provided with the variable buckle joint for being connected with pipeline; Be provided with filter vat in described housing hollow, the top of housing is provided with gas injection valve.Portable well head pipeline of the present utility model note alcohol device, by glycol of annotating in single well pipeline or gathering pipeline, reduces gas dew point and prevents from generating hydrate and then avoid pipeline frozen block, build the pressure, solve a difficult problem for transport gas.There is compact structure, easy to use; Save time, labour-saving advantage, and have cheap, be easy to make, the superiority that has a high potential of marketing.Although this patent solves the problem of pipeline frozen block, the blockage problem caused for the hydrops in rock gas is also unresolved, still can cause the waste of resource.
To sum up, existing solution individual well pipe plugging removal method, easily makes the production waste in pipeline cause environmental pollution near well site, very easily causes Environment Pollution Event, and there is the potential safety hazard of breaking out of fire.
In view of above reason, for preventing the production waste befouling environment in natural gas line, reducing security risk, proposing the device being applicable to well head pipeline sewage and reclaiming.
