Abstract
The utility model discloses a retrieve interior profit composite set of tubular column that promotes contains a sealing sleeve, a connecting rubber pipe, a recovery bucket and a drainage tube, the drainage tube flow in a pit shaft annular space through a well head sleeve pipe and a sleeve pipe valve. The utility model discloses a retrieve interior profit composite set of tubular column has following advantage: the oil-water mixed liquid is collected through the recovery combination device, and the liquid enters the shaft annulus through the drainage tube, so that the environmental pollution in the well repairing operation process is reduced, the oil stain recovery treatment cost is saved, and the well control risk can be effectively avoided.
Description
Technical Field
The utility model relates to an oil production instrument, more precisely, be an interior profit composite set of recovery hoisting tubular column.
Background
In the well repairing operation process, when the oil drainage device is not put into the production string of the oil production well or the string of the drilling and sweeping process is blocked, the mixed liquid of oil and water in the string is directly discharged at the well mouth in the process of lifting the string. The operation process can only be cleaned manually, oil stains pollute the well site environment, and the construction efficiency is reduced. The recovery of waste liquid and oil on the ground is always a main factor troubling production.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the technical problem that prior art exists to an oil water composite set in recovery hoisting tubular column is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the oil-water combination device in the recovery hoisting pipe column is characterized by comprising a sealing sleeve, a connecting rubber pipe, a recovery barrel and a drainage pipe, wherein the drainage pipe flows into a shaft annulus through a wellhead casing and a casing valve.
As the embodiment of the utility model discloses the preferred, the seal cover section of thick bamboo contain half a section of thick bamboo of half a pair of cylindric sleeve, half a section of thick bamboo of sleeve be connected through a pair of loose-leaf, half a section of thick bamboo of sleeve edge be equipped with a locking valve, half an upper edge and the lower limb of sleeve all be equipped with a sealing washer, half a section of thick bamboo lateral wall of one of them sleeve on be equipped with a discharge orifice, discharge orifice with the head of connecting the rubber tube be connected, the afterbody of connecting the rubber tube stretch into the recycling bin.
The utility model discloses a retrieve interior profit composite set of tubular column has following advantage:
the oil-water mixed liquid is collected through the recovery combination device, and the liquid enters the shaft annulus through the drainage tube, so that the environmental pollution in the well repairing operation process is reduced, the oil stain recovery treatment cost is saved, and the well control risk can be effectively avoided.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic connection diagram of the oil-water combination device in the recovery hoisting pipe column of the present invention;
fig. 2 is a schematic structural view of the sealing sleeve of fig. 1.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1 and 2, the oil-water combination device in the recovery lift pipe column comprises a sealing sleeve 1, a connecting rubber pipe 2, a recovery barrel 3 and a drainage pipe 4, wherein the drainage pipe 4 flows into a shaft annulus 7 through a wellhead casing 5 and a casing valve 6.
The sealing sleeve 1 comprises a pair of semi-cylindrical sleeve barrels 11, the semi-cylindrical sleeve barrels 11 are connected through a pair of hinges 12, a locking valve 13 is arranged at the edge of the semi-cylindrical sleeve barrel 11, sealing rings 14 are arranged at the upper edge and the lower edge of the semi-cylindrical sleeve barrel 11, a discharge hole 15 is arranged on the side wall of one of the semi-cylindrical sleeve barrels 11, the discharge hole 15 is connected with the head of the connecting rubber pipe 2, and the tail of the connecting rubber pipe 2 extends into the recovery barrel 3.
The operation of the oil and water combined device in the recovery hoisting column will be described below.
After a single wellhead oil pipe T is broken out, the sealing sleeve 1 is installed, liquid in the oil pipe is discharged into the sealing sleeve 1 by lifting, and flows into the recovery barrel 3 through the connecting rubber pipe 2. By utilizing the liquid level pressure difference principle, the liquid in the recovery barrel 3 flows into the wellhead casing 5 through the drainage tube 4 and finally enters the annular space 7 in the well.
The oil-water mixed liquid is collected through the recovery combination device, and the liquid enters the shaft annulus through the drainage tube, so that the environmental pollution in the well repairing operation process is reduced, the oil stain recovery treatment cost is saved, and the well control risk can be effectively avoided.
Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
