Abstract
The utility model discloses a multifunctional while drilling tube tester. The tube tester is composed of an upper adaptor, a lower adaptor, a cylinder and a pressurized discharge mechanism. The tube tester is characterized in that a hollow cylinder is formed by the connection of the lower end of the upper adaptor, the upper end of the lower adaptor and the two ends of the cylinder through threads; a tapered hole valve seat in the pressurized discharge mechanism is arranged in a cylindrical hole formed in the lower end plane of the upper adaptor, and the tapered hole valve seat is radially fixed through a screw pin below the upper adaptor; a discharge sieve tube in the pressurized discharge mechanism is arranged on an inner threaded hole in the upper end plane of a connector below the inner hole of the cylinder through a thread at the lower end of the discharge sieve tube; in addition, the diameter of the cylindrical hole in the middle of the cylinder is more than the excircle diameters of the discharge sieve tube and the tapered hole valve seat; and the length of the cylindrical hole is greater than the sum of the lengths of the discharge sieve tube and the tapered hole valve seat. The multiple functions of pressurizing a test tube, decompression, recycling and the like can be realized after a fed steel ball or a tapered plug, and the multifunctional while drilling tube tester is reliable in performance, high in economical benefit, and convenient to recover.
Description
Affiliated technical field
The utility model relates to petroleum machinery, the design of underground operation tool " water injection string is tested pipe device ".
Background technology
In the recovery process in oil field, in order to improve the tar productivity of OW, must be to water filling in OW, to recover the energy of oil well.In the injecting process, often need be by the leakage situation of testing pipe device and check tubing string or packer.Due to part test that pipe device tests after pipe cannot pressure release, when tubing string with when testing pipe device and returning to ground, the liquid thereupon going out in tubing string can pollute ground; What also have that part has a decompression function tests pipe device, after pressure release, tests valve seat in pipe device and the part such as steel ball or tapered plug of input and can be shed to down-hole, or cannot reclaim, or salvage difficulty.
Summary of the invention
The purpose of this utility model is to provide a kind of and uses with drilling rod, have test pipe, pressure release and recovery function test pipe device.
The utility model is made up of top connection, cylindrical shell, lower contact and pressurization aerial drainage mechanism, and its difference is: by the lower end of top connection and lower contact upper end, be connected into a hollow cylinder by screw thread and cylindrical shell two ends; Taper hole valve seat in pressurization aerial drainage mechanism, is arranged in the cylindrical hole of top connection lower surface, and radially fixing by a screw rod pin of top connection below; The earial drainage screen casing of pressurization in aerial drainage mechanism, is arranged on the external screw thread of lower end on the internal thread hole of below, lower contact upper surface of cylinder bore.
Because the utility model is arranged on pressurization aerial drainage mechanism in the hollow cylinder of a relative closure of top connection, lower contact and cylindrical shell composition, going deep into behind down-hole along with drilling rod, can keep the unimpeded of liquid.In the time that needs are tested pipe, first in taper hole valve seat, drop into steel ball or tapered plug, form and stop up, rising hydraulic pressure, tests pipe.Test area within a jurisdiction in limited time when hydraulic pressure exceedes, taper hole valve seat can be cut off radially fixing screw rod pin, is shed in cylindrical shell; Hydraulic pressure in drilling rod is immediately by the cylindrical of taper hole valve seat and the gap of cylinder bore, through the pressure release of earial drainage screen casing.In the time that drilling rod returns to ground, the multi-functional pipe device of testing is also integrally taken out of well head, change cut off screw rod pin, by taper hole valve seat reset after, still reusable.
Accompanying drawing explanation
Accompanying drawing is overall structure full section schematic diagram of the present utility model.
Component title shown in attached number in the figure is as follows:
1, top connection, 2, lower contact, 3, cylindrical shell, 4, earial drainage screen casing, 5, screw rod pin, 6, O RunddichtringO, 7, taper hole valve seat.
The specific embodiment
Below with accompanying drawing, the utility model is described in further detail:
There is a taper thread hole upper surface of the utility model top connection (1), uses with the taper thread end of drilling rod and is connected; There is a cylindrical hole lower surface, for taper hole valve seat (7) is installed; Centre is the transition cylindrical hole that runs through taper thread hole, upper surface and lower surface cylindrical hole.The outside of top connection (1), top is one section of cylinder with shallow slot, below is that one section of diameter is thin, have the double-screw bolt of a little screw on sidewall; Double-screw bolt is used with the screwed hole of cylindrical shell (3) upper end and is connected, and screw rod pin (5) is housed in little screw, for the taper hole valve seat (7) in the cylindrical hole of fixing top connection (1) lower surface.The upper surface of lower contact (2) is screwed hole, uses with the lower end of earial drainage screen casing (4) and is connected; Lower surface is a cylindrical hole communicating with upper end screwed hole, for draining.In the outside of lower contact (2), top is one section of double-screw bolt that diameter is thinner, uses with the screwed hole of cylindrical shell (3) lower end and is connected; Centre is the cylinder of transition; Below is one section of cone bar screw thread, uses with the taper hole of drilling rod and is connected.Cylindrical shell (3) is hollow cylinder, and upper and lower both ends of the surface are screwed holes, and centre is to connect cylindrical hole; The diameter of cylindrical hole is greater than the outside diameter of earial drainage screen casing (4) and taper hole valve seat (7), the length of cylindrical hole is greater than the length sum of earial drainage screen casing (4) and taper hole valve seat (7), so as to hold earial drainage screen casing (4) and come off after taper hole valve seat (7).
Pressurization aerial drainage mechanism of the present utility model is made up of earial drainage screen casing (4), screw rod pin (5), O RunddichtringO (6) and taper hole valve seat (7).Earial drainage screen casing (4) is that on a joint upper surface sealing, upper end sidewall, densely covered aperture, lower end are processed with externally threaded hollow section, aperture densely covered on the sidewall of upper end is for draining pressure release, and the external screw thread of lower end is used with the screwed hole on lower contact (2) upper surface and connected.Diameter and the intensity of screw rod pin (5), the waterpower pressure required to testing pipe is directly proportional.Taper hole valve seat (7) is hollow cylinder, and centre is Qie You tri-road grooves on conical through-hole, excircle; Middle conical through-hole is used for accepting steel ball or the tapered plug of input, excircle Shang tri-road grooves: top two road grooves are used for mounting O-shaped sealing ring (6), and one of below groove is used for holding and cutting off the protuberance of screw rod pin (5).
