Abstract
The utility model relates to an perforating and production pipe column for oil field gas wells, which is characterized in that the lower end of an oil pipe (1) with a perforating gun (8) is provided with a piston (4), a working barrel (5) and a gas anchor (6); a sucker rod (3) and a centralizer (2) are arranged in the oil pipe. The utility model has the advantages of simple structure, convenient operation and reliable working, solves the problem of ground layer water leakage in the perforating and production process of the natural gas well, and can carry out direct water discharge and gas production without loading the suction pipe column through the underground operation, thereby reducing the operation workload, and also enhancing the primary production effect of the natural gas well.
Description
Technical field: the utility model relates to a kind of oil field downhole tool, especially for a kind of oil field gas well perforation operation tubing string of the natural gas well.
Background technology: before the utility model, each oil field generally is to play perforation hole operation tubing string earlier for solving the problem of stratum water outlet in the natural gas well perforation operation process, and being lowered to the pumping tubing string again carries out the water pumping gas production job execution; This method has not only increased the work operations amount owing to must finish by underground work, also can influence the initial stage operation effect of the natural gas well.
Summary of the invention: the purpose of this utility model is: going into operation for the natural gas well provides a kind of oil field gas well perforation operation tubing string, because this device is equipped with oil well pump, when the stratum water outlet needs water pumping gas production after perforation is finished, can directly carry out swabbing operation, need not to be lowered to the pumping tubing string by underground work again, not only reduce the work operations amount, also improved the initial stage operation effect of the natural gas well.
The purpose of this utility model realizes by following measure: a kind of oil field gas well perforation operation tubing string, be to constitute by oil pipe, centralizer, sucker rod, piston, seating nipple, gas anchor, connecting rod, perforating gun, and oil pipe connects perforating gun by connecting rod, it is characterized in that the oil pipe lower end is equipped with piston, seating nipple and gas anchor, sucker rod and centralizer also are installed in its pipe.
The utility model is simple in structure, easy to operate, reliable operation, be used for solving in the problem of natural gas well perforation operation process stratum water outlet, need not to be lowered to the pumping tubing string by underground work again, just can directly carry out water pumping gas production, not only reduce the work operations amount, also improved the initial stage operation effect of the natural gas well.
Description of drawings: Fig. 1 is the structural representation of oil field gas well perforation operation tubing string.
The specific embodiment: oil field gas well perforation operation tubing string is to be made of oil pipe 1, centralizer 2, sucker rod 3, piston 4, seating nipple 5, gas anchor 6, connecting rod 7, perforating gun 8 etc., oil pipe 1 connects perforating gun 8 by connecting rod 7, oil pipe 1 lower end is equipped with piston 4, seating nipple 5 and gas anchor 6, and sucker rod 3 and centralizer 2 also are installed in its pipe.
The operating principle and the using method of oil field gas well perforation operation tubing string are: earlier this device is lowered to precalculated position, natural gas well down-hole to be gone into operation before using, just can starts perforating gun 8 by hydraulic way and carry out the perforation construction, carry out gas well then and go into operation; When the back stratum water outlet of going into operation influences normal gas production, just can transfer sucker rod 3 connection pistons 4 and directly carry out water pumping gas production, thereby having realized need not is lowered to the pumping tubing string by underground work again, just can carry out the swabbing operation construction.
