Description
Technical field
The utility model belongs to oil gas field gas production production technical field, is related to bubble mining gas bubble rod row, and in particular to one
Kind oil gas field gas production floatation type bubble rod row.Bubble rod row described in the utility model is particularly suitable for use in low yield gas watered-out well.
Background technology
As gas well gas production enters the middle and later periods, gas reservoir pressure and natural gas flow speed gradually reduce, cause stratum water or
Condensed liquid can not carry out pit shaft with the air-flow of natural gas, cause its edge water propelling and bottom water to rise.After a period of time, these
Liquid accumulation is subsequently formed in shaft bottom, fluid column, has a strong impact on the normal production of gas well.If this situation continues, in pit shaft
Excessive hydrops is formed, back pressure will be more than strata pressure, then cause gas well water logging, and the fluid column assembled in pit shaft can also kill
Gas well, gas well is caused to stop production.
In order to improve gas well recovery ratio, liquid discharging gas producing, conventional water pumping gas production work are carried out using various ways at present
Skill mainly include downhole choke water pumping gas production, plunger lift water pumping gas production, foam drainage gas recovery, supercharging suction water pumping gas production and
Optimizing pipe string water pumping gas production.Wherein, foam drainage gas recovery technique is water pumping gas production method the most frequently used in oil gas field gas production production
One of.A number of foaming agent is injected into well first, after shaft bottom ponding contacts with foaming agent, by stirring for natural gas flow
It is dynamic, the resistance aqueous foam of a large amount of low-density is generated, ground is carried to from shaft bottom with air-flow, reaches the purpose for removing shaft bottom hydrops.Together
When, after the natural gas for carrying bubble stream rises to ground, to prevent foam from bringing surface technology equipment into, influence normally to produce,
Defoamer need to be also injected into pipeline, foam is removed before foam enters equipment.Connect due to being had using foam drainage gas recovery
It is continuous effectively, stratum is not damaged, strong adaptability the advantages that, therefore, this method is increasingly valued by people.
Patent CN205532533U discloses a kind of special propeller type bubble rod row of low yield gas watered-out well, and it will be by foam discharging agent system
Into the molding of three pieces of fan leafs and cone be formed as one propeller-like.The design of three pieces of fan leafs increases to a certain extent
The contact area of foam discharging agent and shaft bottom hydrops, shortens dissolution time of the bubble rod row in the hydrops of shaft bottom, but this bubble rod row
Prepare complicated and be not easy to store and use.
Patent CN205314974U provides a kind of special bubble rod row of low yield gas watered-out well, is provided with the barred body of bubble rod row
The through hole that bubble rod row both ends of the surface are penetrated, the cross section of bubble rod row is circular or polygon.This patent is made by the change of profile
Obtain bubble rod row to be easy to react in the hydrops of shaft bottom, but the application effect of the bubble rod row is difficult to ensure that.
Patent CN203079903U relate to a kind of automatic gas-producing environment-protective honeycomb coaly inhibition bubble rod row, its technological core be
4 hollow cylinders in honeycomb coaly are evenly distributed with cylinder, the hollow cylinder of honeycomb coaly improves rising for bubble rod row
Bubble ability, but hollow cylinder and can effectively shorten reaction time of the bubble rod row in the hydrops of shaft bottom, cause bubble rod row to sink to well
Bottom.
Existing oil gas field gas production bubble rod row is made into bar shape more, due to self structure, conventional bubble rod row or certainly angry
Type bubble rod row all has the disadvantage that：
（1）Bubble rod row density is usually 1.2~1.4g/cm3, more than 1.05~1.15g/cm of wellbore effusion density3, input
Shaft bottom can be gradually sunk to after well, the depth that bubble rod row immerses wellbore effusion is deeper, and the pressure that bubble rod row is subject to is bigger, is more not easy
Bubble is produced, causes that foaming effect can not be given full play to, severe patient can block shaft bottom；
（2）Cylinder bubble rod row and wellbore effusion contact surface are small, and dissolution velocity is relatively slow, can not effectively play bubble row
The effect of rod.
Therefore, in order to effectively solve problem above, urgent need researches and develops a kind of economical and effective low production and low pressure gas well bubble rod row,
It is effectively shortened foamed time, effectively improve its lifting and drainage capacity, recover itself production capacity of gas well.
The content of the invention
The utility model is in view of the above-mentioned problems, provide a kind of oil gas field gas production floatation type bubble rod row.The utility model leads to
The optimization design to bubble rod row outer shape and internal structure is crossed, significantly increases the contact surface of bubble rod row and wellbore effusion
Product, and this bubble rod row can float on wellbore effusion top, increase foam number, add discharge opeing effect.
To achieve these goals, the utility model takes following technical scheme：
A kind of oil gas field gas production floatation type bubble rod row, including the cylindric barred body made of foam discharging agent, it is described cylindric
Barred body is provided at both ends with arc-shaped transition section, and the surface of the cylindric barred body and arc-shaped transition section is provided with screw thread, described
The inner hollow of cylindric barred body.
Further, the length of the cylindric barred body inner hollow section is not less than the 1/2 of the bubble rod row length.
One of preferred embodiment as the technical program, the section of the cylindric barred body inner hollow to be circular or
Polygon.
Further, the screw thread on the cylindric barred body surface is in unidirectional array or bi-directional arrangement.
One of preferred embodiment as the technical program, the screw thread arrangement mode and circle of the arc-shaped transition section surface
The screw thread on column barred body surface is identical.
Further, the screw thread is continuously connected by multiple prism-frustum-shaped raised bodies and formed, and adjacent two on same screw thread
Groove is formed between individual prism-frustum-shaped raised body.
One of preferred embodiment as the technical program, the prism-frustum-shaped raised body is in the same bubble rod row
Specification is identical.
One of preferred embodiment as the technical program, the side quantity of the polygon are at least three.
Compared with existing bubble rod row, oil gas field gas production described in the utility model at least has following with floatation type bubble rod row
Beneficial effect or advantage：
The oil gas field gas production floatation type bubble rod row that the utility model provides, can be taking human as according to the difference of contour structures
The middle part that is divided into there is the cylindric barred body of hollow structure, and the arc-shaped transition section at cylindric barred body both ends.Cylindric
The surface of barred body and arc-shaped transition section is provided with screw thread.Further, the length of the cylindric barred body inner hollow section is not small
In the 1/2 of the bubble rod row length.
While bubble rod row component formula is optimized, the utility model is improved the component structure of bubble rod row.It is logical
The change of said structure is crossed, the density of the bubble rod row is less than wellbore effusion density so that bubble rod row is swum in wellbore effusion
Portion, or the part-cylindrical barred body of bubble rod row are suspended in the hydrops of shaft bottom.Bubble rod row can so be effectively shortened by shaft bottom
The time that hydrops corrodes, increase foam number.Bubble rod row described in the utility model is particularly suitable for use in low yield gas watered-out well.In oil gas
In the gas production operation application of field, compared with existing bubble rod row, the bubble rod row improves discharge opeing effect, adds the gas production of gas well
Amount.
