Description
Technical field
This utility model relates to oil extraction in oil field technical field, particularly to a kind of gas well water pumping gas production tubing string.
Background technology
In casinghead gas well development production process, during producing gas, always with the generation of oil with water in Wellbore of Gas Wells, once in pit shaft, oil is too high with the liquid level of water, the pressure that its hydrostatic column produces has had a strong impact on gas well yield, the most general measure is that upper coiled tubing carries out draining, and general several days of engineering time, operating cost is the highest.
Utility model content
It is unique that the purpose of this utility model is to provide a kind of novel structure, easy to use, and can the casing-head gas well array hydromining trachea post of draining at any time；Concrete technical scheme is:
A kind of casing-head gas well array hydromining trachea post, including sleeve pipe, oil pipe and testing tube；Described oil pipe and described testing tube are placed side by side and are set in described sleeve pipe, and the lower port of testing tube connects with oil pipe, and oil pipe bottom is provided with floral tube, is provided with the ball-and-seat upwards circulated between oil pipe and described floral tube；Inside pipe casing, is provided with packer outside oil pipe, described packer is arranged on below the lower surface of described testing tube.
Further, described ball-and-seat is one way valve.
Further, described ball-and-seat is arranged on below the lower port of described testing tube and the connected entrance of described oil pipe.
Further, described packer is Y441 packer
Further, described floral tube is without plug floral tube.
Further, the lower port of described testing tube with described oil pipe by connecting fittings.
Further, described testing tube is fixed on the outer wall of described oil pipe by pipe clamp.
Further, the bottom of described floral tube is the bell that bottom is big.
This utility model casing-head gas well array hydromining trachea post is by connecting the lower port of testing tube with oil pipe, and at the lower port of testing tube and the connected entrance of oil pipe ball-and-seat arranged below；Utilize nitrogen to enter oil pipe from testing tube, oil pipe is discharged in hydrops jacking, it is to avoid the pressure that hydrostatic column the produces obstruction to gas, improve gas well yield.
Accompanying drawing explanation
Fig. 1 is this utility model casing-head gas well array hydromining trachea rod structure schematic diagram.
In figure: 1, sleeve pipe；2, oil pipe；3, testing tube；4, pipe clamp；5, connection joint；6, packer；7, ball-and-seat；8, floral tube.
Detailed description of the invention
Below with embodiment, this utility model is more fully illustrated.This utility model can be presented as multiple multi-form, is not construed as the exemplary embodiment being confined to describe here.
For ease of explanation, here can use such as " on ", the space relative terms such as D score " left " " right ", for shown in explanatory diagram a element or feature relative to another element or the relation of feature.It should be understood that in addition to the orientation shown in figure, spatial terminology is intended to include device different azimuth in use or operation.Such as, if the device in figure is squeezed, be stated as being positioned at the element of other elements or feature D score will be located into other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower both orientation.Device can otherwise position (90-degree rotation or be positioned at other orientation), relatively illustrates used herein of space correspondingly to explain.
As it is shown in figure 1, the casing-head gas well array hydromining trachea post in the present embodiment, including sleeve pipe 1, oil pipe 2 and testing tube 3；Oil pipe 2 and testing tube 3 are placed side by side and are set in sleeve pipe 1, and the lower port of testing tube 3 connects with oil pipe 2, and oil pipe 2 bottom is provided with floral tube 8, are provided with the ball-and-seat 7 upwards circulated between oil pipe 2 and floral tube 8；Sleeve pipe 1 is internal, and oil pipe 2 is outside is provided with packer 6, and packer 6 is arranged on below the lower surface of testing tube 3.Packer uses Y441 packer.
Ball-and-seat 7 can use one way valve, if desired, is opened by ball-and-seat, cancels one-way flow and limits.
Ball-and-seat 7 is arranged on below the lower port of testing tube 3 and the connected entrance of oil pipe 2；Avoid the nitrogen entered from testing tube 3 to connect with producing gas, make nitrogen be completely used for jacking hydrops.
Floral tube 8 in tubing string can be without plug floral tube；Be conducive to improving the yield of gas.
The lower port of testing tube 3 connects by connecting joint 5 with oil pipe 2, is convenient for changing testing tube 3, and air collecting pipe post can be made to adapt to the production layer of different depth by the length changing testing tube 3.
Testing tube 3 can be fixed on the outer wall of oil pipe 2 by pipe clamp 4；Can also be fixed on by other means on the outer wall of oil pipe 2.
The bottom of floral tube 8 could be arranged to the bell that bottom is big, such as horn mouth shape；Be conducive to collecting more gas.
During specific works, gas enters oil pipe from floral tube 8 through ball-and-seat 7, rises to the top of well.Owing to containing a small amount of oil or water in gas, in gas recovery, the liquid such as oil or water gradually deposits in ball-and-seat 7 upper end, forms the static pressure fluid column with certain altitude in oil pipe 2.Along with the height of static pressure fluid column increases, the pressure of generation is the biggest, the gas exported via oil pipe 2 can be produced pressure, reduce the yield of gas.When detecting that tolerance reduces, open valve, high pressure nitrogen is filled with testing tube 3, the high pressure nitrogen connected entrance from testing tube 3 lower end enters in oil pipe 2, and liquid jacking is released oil pipe 2 by the top of ball-and-seat 7, reduce the height of static pressure fluid column, thus promote the yield of gas.
Above-mentioned example be only intended to illustrate this utility model, in addition, the most multiple different embodiment, and these embodiments be all those skilled in the art after comprehension this utility model thought it is also envisioned that therefore, will not enumerate at this.
