A kind of gas well production liquid storage device with multistage defoaming function

Technical field

The utility model relates to natural gas well production practice auxiliary devices, in particular to a kind of to have multistage defoaming function Gas well produce liquid storage device.

Background technique

In gas exploitation course, since geology stressor layer is higher, water gasifies under high-pressure situations, generally with natural gas It is exported together from gas recovery well well head, still, as natural gas and gaseous water are constantly extracted out from geological stratification, pressure in gas recovery well It gradually decreasing, gaseous aqueous vapor is liquefied as liquid water, and hydrops is formed in natural gas well bottom, influences the normal output of natural gas, So liquid or solid bubble row's medium can frequently be added in the gas well later period at present, connect using shaft bottom ponding and bubble row's medium After touch, by the agitation of shaft bottom gas flow, the foam of a large amount of low-density is generated, carries from shaft bottom to ground, reaches with air-flow To the purpose for removing shaft bottom hydrops.

Gas recovery well periphery water source environment can be polluted since the foam-like gas well of gas well output produces liquid, according to environmental requirement, gas Well produces the necessary centralized collection processing of liquid, currently, most well station takes conventional fluid reservoir storage gas well to produce liquid, still, due to Gas well produces liquid major part show bubble, does not also carry out special defoaming treatment when inputting fluid reservoir, and gas well produces liquid input It needs to defoam automatically by the standing of long period in fluid reservoir, and foam-like gas well produces liquid and occupies biggish space, leads It causes the capacity utilization of fluid reservoir lower, and fluid reservoir is made to be easy to cause the land pollution of well station there are the hidden danger of foam overflow, Also it is unfavorable for the implementation of gas well flowing back maintenance measure, influences gas well liquid loading.

In conclusion at present there is an urgent need for a kind of technical solution, solves existing gas well and produce liquid when inputting fluid reservoir not Defoaming treatment is carried out, causes the capacity utilization of fluid reservoir lower, and fluid reservoir is made to influence gas there are the hidden danger of foam overflow The technical issues of well produces.

Utility model content

The purpose of this utility model is that: liquid, which is produced, for existing gas well does not carry out at defoaming when inputting fluid reservoir Reason, causes the capacity utilization of fluid reservoir lower, and fluid reservoir is made to influence the skill of gas well liquid loading there are the hidden danger of foam overflow Art problem provides a kind of gas well production liquid storage device with multistage defoaming function.

To achieve the goals above, the technical solution adopted in the utility model are as follows:

A kind of gas well with multistage defoaming function produces liquid storage device, including fluid reservoir, is provided on the fluid reservoir Inlet is provided at least one defoaming device in the fluid reservoir.

A kind of gas well with multistage defoaming function of the utility model produces liquid storage device, by being arranged in fluid reservoir Defoaming device is reduced so that the gas well exported from the oil pipe and/or casing of christmas tree produces liquid passes through defoaming treatment in fluid reservoir Gas well produces the air bubble content in liquid in fluid reservoir, the capacity utilization of fluid reservoir is improved, simultaneously as into the gas well of fluid reservoir Produce in liquid that bubble content is less, the foam for being also beneficial to avoid gas well to produce in liquid occupies the biggish space of fluid reservoir, cause into According to the actual situation, multiple defoaming devices are arranged in foam overflow during liquid, the utility model in fluid reservoir, are formed multistage Mechanism is defoamed, the bubble in the gas well production liquid for entering fluid reservoir is reduced to the greatest extent, improves the capacity utilization of fluid reservoir.
