Abstract
The utility model relates to a pulling and running tool for testing the pressure of a pipe string, composed of a connecting rod 1, a sleeve barrel 2, a water inlet canal 4, a valve ball 7, a pressure relief pore canal 11, a guide rod 12, etc. the water inlet canal 4 is arranged on the side edge of the sleeve barrel 2, the lower end of the connecting rod 1 is connected with a valve cover 6 in which the valve ball 7 is arranged, the guide rod is connected with the sleeve barrel 2, the pressure relief pore canal 11 is arranged inside the guide rod, and the upper end of the pressure relief pore canal 11 is provided with a valve seat 8 in the shape of an inverted round platform. The utility model can avoid the occurrence of underground accidents, and has the advantages of good sealing effect, simple structure, and convenient installation and operation.
Description
The utility model relates to a kind of tubing string pressure testing throw in catcher, and the genus tubing string is suppressed and tested leakage technical field.
My oil field has the part well to adopt the gas artificial lifting way to recover the oil at present, the tubing string of this gas-lift well is an open gas lift well casing post, can't pressure testing after the operation completion, can not check the sealing of whole tubing string, so tubing string is after the perforation of a certain non-gas lift valve place, the gas of hanking is dammed, and has influenced the operate as normal of stage further gaslift, make the well that firm operation is intact, the back output that drives a well does not reach designing requirement.
The purpose of this utility model is to provide a kind of can test the pressure testing throw in catcher of leakage work rapidly and accurately to whole tubing string.
The utility model is achieved in that it is by connecting rod 1, sleeve 2, spring 3, intake tunnel 4, spring base 5, valve cover 6, all and ball 7, valve seat 8, adjust ring 9, sealing ring 10, pressure release duct 11, guide rod 12 is formed, one garden shape jack is arranged at sleeve 2 tops, the lower end is provided with internal thread, side has bar shaped intake tunnel 4, connecting rod 1 is a solid Cylinder, two ends are provided with external screw thread, insert out from the garden shape jack on sleeve 2 tops its upper end, the lower end is threaded with the valve cover 6 of interior dress valve ball 7, be provided with a step spring base 5 at the middle part of connecting rod 1, on the connecting rod 1 of 2 in spring base 5 tops and sleeve, be with spring 3, guide rod 12 tops are threaded with sleeve 2, on guide rod 12, be with O-ring seal 10 and adjust ring 9, guide rod inside is provided with pressure release duct 11, and 11 upper ends, pressure release duct are the valve seat 8 of the platform of falling garden shape.
The utlity model has following advantage: 1. adopt ball face sealing, good sealing effect; 2. adopt the decompressing by pinhole passage, whole throw in catcher is carried to ground on still can be easily under the high pressure fluid column effect do not pulled off steel wire for logging, avoid the generation of down-hole accident; 3. simple in structure, easy to install.
Fig. 1 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is further described:
As shown in the figure: the utility model is by connecting rod 1, sleeve 2, spring 3, intake tunnel 4, spring base 5, valve cover 6, all and ball 7, valve seat 8, adjust ring 9, sealing ring 10, pressure release duct 11, guide rod 12 is formed, one garden shape jack is arranged at sleeve 2 tops, sleeve 2 lower ends are provided with internal thread, side has bar shaped intake tunnel 4, connecting rod 1 is a solid Cylinder, two ends are provided with external screw thread, insert out from the garden shape jack on sleeve 2 tops its upper end, the lower end is threaded with the valve cover 6 of interior dress valve ball 7, be provided with a step spring base 5 at the middle part of connecting rod 1, on the connecting rod 1 of 2 in spring base 5 tops and sleeve, be with spring 3, guide rod 12 tops are threaded with sleeve 2, on guide rod 12, be with O-ring seal 10 and adjust ring 9, guide rod inside is provided with pressure release duct 11, and 11 upper ends, pressure release duct are the valve seat 8 of the platform of falling garden shape.
The upper end screw thread and the rope socket of throw in catcher upper connecting rod 1 are linked together, with the fixing back of steel wire for logging G.I.H, be that O-ring seal 9 on the throw in catcher is pressed on the conical surface of pressure text head, this moment, steel wire for logging became free, spring 3 is pushing away valve ball 7 motion together downwards in the connecting rod 1 lower end valve cover 6, on valve ball 7 is pressed on valve seat 8 on the guide rod 12, oil pipe is inner thoroughly to be separated with the oil jacket annular space thereby make, as requested tubing string is carried out pressure testing, pressure testing is carried steel wire for logging on the intact back, rope socket drives connecting rod 1 and moves upward, and pressuring spring 3 shrinks simultaneously, thereby makes valve ball 7 break away from valve seat 8, at this moment open in the pressure release duct 11 on the guide rod 12, tubing string inner high voltage liquid flows to the shaft bottom through pressure release duct 11, shed fluid column in the oil pipe and has been pressed in high pressure on the whole throw in catcher, thereby carried throw in catcher to ground on can be easily.
