Abstract
The utility model provides a pipeline type filtering desander. The pipeline type filtering desander mainly comprises an outer sleeve shell, a filtering desanding pipe assembled in the outer sleeve shell, and an air inlet connecting pipe and an air outlet connecting pipe which are arranged on the outer sleeve shell, wherein a group of strip-shaped filtering holes are formed in a pipe wall of the filtering desanding pipe, and the hole width is controlled to be smaller than the particle size of ceramic sand. The collected natural gas can be filtered, the ceramic sand particles are completely blocked in the filtering desanding pipe, pure natural gas in which the ceramic sand particles are filtered is output through an output gas pipe, and the aim of performing gas and sand filtering separation on the natural gas can be achieved. The pipeline type filtering desander has the advantages of effectively prolonging the service life of gas pipeline equipment, along with simple structure, easy production, low manufacturing cost, convenience in operation and management and good filtering desanding effect, and has excellent application prospects in gas recovery operations of natural gas wells.
Description
Technical field
The utility model relates to the attached corollary equipment that carries out gas production operation at the natural gas well, and specifically a kind of duct type filters desander, and it can remove by filter the ceramic sand grains mixing in natural gas to the gas gathering.
Background technology
We know: according to the requirement of natural gas well drillng operation technical matters, in drilling operation course, generally all need to inject a large amount of ceramic sand, the ceramic sand of this drilling well special use is that particle diameter is the hard particles of 0.35-0.8mm, and it has, and endoplasm is hard, the physical characteristic of expolasm sharp surface extreme hardness.According to production operation field investigation, understand: after natural gas well drillng operation, having a large amount of ceramic sand retains in the natural gas well and is difficult to remove, when the natural gas well drops into after formal production run, always have some ceramic sand one by one along with gathered high pressure (referring generally to pressure is 20MPa) natural gas together ejection, although mix the quantity of ceramic sand grains in high-pressure natural gas seldom, but because the surface of these ceramic sand is hard sharp and be to be accompanied by high-pressure natural gas high-speed motion in gas pipeline, without doubting, these ceramic sand grains all have very havoc effect to warehousing and transportation facilities such as gas pipeline and pressure regulation meterings.This also just the gas pipeline facility of existing natural gas well there is in actual use the main cause that working life is shorter, maintenance time is long, operational and administrative expenses is high.Tell it like it is, natural gas production management department also wishes to solve " how removing the ceramic sand grains mixing in natural gas " this technical problem in persistent exploration always, but up to now, still do not find good solution, also the pertinent literature of not seeing relevant " filter and remove ceramic sand in natural gas " equipment, the utility model wants to solve this problem exactly.
Utility model content
The purpose of this utility model is intended to propose a kind of duct type and filters desander; it can filter also the ceramic sand grains in filtering natural gas effectively to the natural gas gathering; effectively avoid ceramic sand grains to scratch and damage gas pipeline equipment, it all has positive effect to extending the working life of gas pipeline equipment and then reducing maintenance management running cost.
The purpose of this utility model is achieved by the following technical solution:
A kind of duct type the utility model proposes filters desander, it comprises that outer tube housing and the filtration being fitted in outer tube housing remove sandpipe, the front end of socket case is provided with inlet pipe connection outside, the rear end of socket case is provided with outer tube flange outside, on the rear end tube wall of socket case, the tube connector of giving vent to anger is installed outside, it is characterized in that: the inner tube at inlet pipe connection is provided with sliding pipe arrangement mouth, at the front pipe end filtering except sandpipe, be provided with the encasement tube interruption-forming sliding supporting load connecting structure suitable with sliding pipe arrangement mouth, in filtration, except on the tube wall of sandpipe, be provided with one group of bar shaped filter bores, be connected in the blind plate filtering except pipe end after sandpipe and be connected closed structure with outer tube flange formation flange.Its remarkable design feature is: the filtration that is provided with one group of bar shaped filter bores is formed to duct type except sandpipe is fitted in outer tube housing and filter desanding structure, and the width of controlling bar shaped filter bores is less than the particle diameter of ceramic sand.It is performed such work: by inlet pipe connection, the natural gas input of gas well collection is filtered except carrying out isolated by filtration pottery sand grains in sandpipe, the ceramic sand grains mixing in natural gas is to be barred from and to be filtered except in sandpipe by bar shaped filter bores, natural gas gas can be smoothly through one group of bar shaped filter bores and enter in overcoat tube chamber, and then by gas outlet tube downstream pipeline section export the pure natural gas gas of filtering pottery sand grains.In actual production operation process, only need periodically change the outfit to filter except sandpipe leans outward by technology requirement and pour out ceramic sand, also can centralized recovery ceramic sand can reuse for drillng operation.So far, can ideally realize the utility model and to gathering out natural gas, filter the goal of the invention of gas sand separation.
Furthermore, the utility model also has following technical characterictic:
The inwall of socket case is installed with supporting filter except the guide rail of sandpipe outside.This structure design has good supporting positioning action to filtering desanding pipe, can on guide rail, pass reposefully and filter except sandpipe, be convenient to especially filter and slide the operation that supporting load connects except the suit mouth of pipe of sandpipe and the sliding pipe arrangement mouth of inlet pipe connection, meanwhile, be also convenient to take out filtration and remove the operation that sandpipe is toppled over removing ceramic sand.
On inlet pipe connection, be fitted with input air pressure table, on the tube connector of giving vent to anger, be fitted with output pressure table.In actual production operation, can change understand the operation conditions of duct type filtration desander and then understand the filtration resistance of filtering except sandpipe inside by observing the pressure of input air pressure table, output pressure table, when output pressure is down to the force value setting, can change the outfit and filter the operation that removes sandpipe and topple over sand removal.
The utility model compared with the existing technology tool has the following advantages:
The utility model has been initiated the interior equipped desanding pipe that filters of socket case outside and has been formed encasement tube road formula filtration desanding structure, on filtration desanding tube wall, one group of wide bar shaped filter bores that is less than ceramic sand particle diameter in hole is set.It can filter desanding and ceramic sand grains is barred from is filtered except in sandpipe completely the natural gas gathering, by gas outlet tube downstream pipeline section export pure natural gas gas, can realize the object of natural gas being filtered to gas sand separation.The utlity model has simple in structure, manufacture that cost is low, operation convenient management, to filter desanding effect good and effectively extend the outstanding advantages of gas pipeline service life of structure.
