Abstract
The utility model relates to an airtight oil tube buckle device which is composed of a sectioning sleeve (1), a shell body (2) and a hinge (4). The airtight oil tube buckling device is characterized in that the sectioning sleeve (1) is composed of two isometrical ladder type semi-circle bodies. A ladder-shaped groove is arranged in the middle of the outer surface of the sectioning sleeve (1) in the axial direction. A ladder-shaped key protrusions matched with the ladder-shaped groove of the sectioning sleeve (1) is arranged in the middle of the inner surface of the shell body (2) in the axial direction. The sectioning sleeve (1) and the shell body (2) are embedded together. The hinge (4) is welded on the shell body (2). The shell body (2) is composed by two independent isometrical semi-circle barrels which are connected together through the hinge (4). According to the airtight oil tube buckling device, operational requirements of airtight oil tubes with different sizes can be met, and the airtight oil tube seal end face can be protected when screw threads are connected. Leak tightness of completion pipe string is ensured.
Description
Technical field
The utility model relates to the oil pipe thread protective device of using in a kind of lower airtight oil pipe column operation process.
Background technology
At present, under the gas well well workover in the airtight oil pipe operation, when thread, airtight oil pipe pin thread is put into airtight oil pipe box (tubing coupling) process, because hook rocks, operates the factors such as unstable, cause easily the direct collision of airtight oil pipe pin end sealing surface in airtight oil pipe box (tubing coupling) upper end, damage airtight oil pipe pin end sealing surface, cause defective oil pipe to enter well, have a strong impact on construction quality.
The utility model content
For above-mentioned technological deficiency, the utility model provides a kind of airtight oil pipe to draw and buckles device, be connected with airtight oil pipe thread, avoid the airtight oil pipe pin end sealing surface airtight oil pipe box of direct collision (tubing coupling) upper surface injury, avoid defective oil pipe to enter well, satisfy the technological requirement of airtight oil pipe workover treatment.
For solving the problems of the technologies described above, the airtight oil pipe of the utility model draws buckles device, by distinguish protect hoop 1, housing 2 and hinge 4 form, wherein, above-mentioned distinguish protects hoop 1 and is comprised of two large notch cuttype semicircular body such as grade, its axial external surface middle part is provided with dovetail groove; Housing 2 axial inner surface middle parts are provided with distinguish protects the trapezoidal key shape projection that hoop 1 dovetail groove is complementary, distinguish protects hoop 1 and is embedded in housing 2, above-mentioned hinge 4 is welded on the housing 2, and above-mentioned housing 2 is comprised of more than half cylinders such as two independences, links together by hinge 4.
Welding handle 3 on the above-mentioned housing 2.
Above-mentioned distinguish protects hoop 1 upper end 45 degree chamferings is set.
The airtight oil pipe of the utility model draws buckles device, can when connecting airtight oil pipe thread airtight oil pipe pin thread be introduced in the box (tubing coupling), effectively protects airtight oil pipe pin end sealing surface, guarantees the sealing of completion tubular column.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
Fig. 1 is that the airtight oil pipe of the utility model draws the structural representation of buckleing device;
Fig. 2 is that the airtight oil pipe of the utility model draws the top view of buckleing device.
The specific embodiment
As depicted in figs. 1 and 2, the airtight oil pipe of the utility model draw buckle device by distinguish protect the hoop 1, housing 2 and hinge 4 form, distinguish protects hoop 1 and is embedded on the housing 2 by dovetail groove, housing 2 links together by hinge 4, during lower airtight oil pipe operation, before the connected pipes screw thread, apparatus of the present invention are sleeved on the oil pipe box (tubing coupling), housing 2 does not upwards knock distinguish and protects hoop 1 relatively when the tubing string size is not mated, make distinguish protect hoop 1 and withdraw from dovetail groove, change the distinguish that adapts to the tubing string size and protect hoop 1, utilize distinguish to protect 45 degree chamferings of hoop 1 upper end, airtight oil pipe pin thread is introduced in the box (tubing coupling), avoided the airtight oil pipe pin end sealing surface airtight oil pipe box of direct collision (box cupling) upper surface, injury, distinguish protects hoop 1 material hardness far below airtight oil pipe simultaneously, so can not damage airtight oil pipe pin end sealing surface, behind airtight oil pipe pin thread introducing box (tubing coupling), operating personnel move handle 3 to the hinge direction and open housing 2, withdrawing from airtight oil pipe draws and buckles device, tighten screw thread with the oil jacket pipe wrench, reach the prescribed torque value, finally guarantee the sealing of completion tubular column.
The airtight oil pipe of the utility model draws buckles the airtight oil pipe job requirements that device can adapt to different size, protects airtight oil pipe seal face when thread, guarantees the sealing of completion tubular column.
Claims (3)
