Abstract
The utility model discloses a hollow rod one-way air lifting drainage gas production device, which is designed for solving the problems that accumulated water in a shaft is recharged to a stratum and the drainage efficiency is low in the conventional air lifting operation. The device mainly comprises an oil pipe valve and a high-pressure incoming gas pipeline which are connected with a wellhead oil pipe, packers and a one-way valve which are arranged at the bottom of an underground oil pipe, a hollow rod arranged in the center of the oil pipe, a gas production pipeline valve and a gas production pipeline which are connected with the hollow rod and the like. High-pressure incoming gas annularly enters a well from a pipe rod and acts on a gas-liquid two-phase interface, and a U-shaped pipe is formed in the space of the pipe rod, so that liquid level in the rod rises. When the liquid in the pipe rod is continually discharged and the pressure in the U-shaped space is reduced to be lower than the pressure in a sleeve, the one-way valve is opened, the accumulated liquid in the sleeve enters the U-shaped space, and continuous air lift is realized. The device can realize continuous air lift of the accumulated liquid in the shaft of a gas well, is easy and convenient to operate, can prevent the accumulated liquid from being recharged to the stratum, can be used for various gas production wells, and improves the yield of single wells.
Description
Technical field
The utility model relates to the unidirectional gaslift water pumping gas production of a kind of hollow stem device, belongs to the gas well draining and takes technical field.
Background technology
Gas well was produced to the later stage, and output is successively decreased gradually, and fluid-carrying capability reduces, and the gas well pit shaft produces hydrops.The existence of hydrops influences the gas well ordinary production, pollutes gas-bearing formation, thereby further reduces gas well deliverability.The production scene, gas field adopts water drainage-gas recovery technologies such as preferred tubing string and gaslift to improve well yield usually, and conventional gaslift causes ponding to recharge the stratum easily, and discharge opeing efficient is lower.
Summary of the invention
The purpose of the utility model is to provide the unidirectional gaslift water pumping gas production of a kind of hollow stem device, and it can avoid pit shaft ponding to recharge the stratum, and integrated capillary bubble row advantage realizes continuous gas lift.
The concrete technical scheme of the utility model is following:
Well head top oil pipe connects tubing valve and comes the tracheae line through high pressure line valve connection high pressure, and oil pipe outside, well head top is provided with sleeve valve.Packer is located at the down-hole oil tube bottom, and the packer top connects one way valve.Hollow stem is located at the oil pipe center, and its top connects flow line through the flow line valve, and down-hole to one way valve top is stretched in the bottom.
The utility model can be realized the continuous gas lift of gas well pit shaft hydrops, and is easy and simple to handle, can avoid hydrops to recharge the stratum, can be used for various product aqueous vapor wells, improves well yield.
Description of drawings
Accompanying drawing is the unidirectional gaslift water pumping gas production of a hollow stem apparatus structure sketch map.
The specific embodiment
Embodiment:
Embodiment to the utility model further specifies with reference to accompanying drawing:
Well head top oil pipe 2 connects tubing valve 7 and comes tracheae line 9 through high pressure line valve 10 connection high pressure, and oil pipe 2 outsides, well head top are provided with sleeve valve 8.Packer 5 is located at down-hole oil tube 2 bottoms, and packer 5 tops connect one way valve 4.Hollow stem 1 is located at oil pipe 2 centers, and its top connects flow line 11 through flow line valve 6, and down-hole to one way valve 4 tops are stretched in the bottom.
High pressure comes gas to get in the well from the pipe burr shape space between oil pipe 2 and the hollow stem 1, acts on the gas-liquid two-phase interface, and pipe bar space forms the U-shaped pipe, makes liquid level rising in the bar.Liquid is constantly discharged in the pipe bar, and when the pressure in the U-shaped space was brought down below sleeve pipe 3 internal pressures, the one way valve 4 of hollow stem 1 below was opened, and the hydrops in sleeve pipe 3 spaces gets into the U-shaped space, realizes continuous gas lift.
During practical operation, one way valve 4 is lowered to oil pipe 2 bottoms, and seat is gone into unidirectional valve seat through oil pipe 2; With hollow stem 1 in the oil pipe 2 at the bottom of the lower going-into-wells; Come tracheae line 9, high pressure line valve 10 and tubing valve 7 to connect oil pipe 2 high pressure.During bubble row, close tubing valve 7 and sleeve valve 8, open high pressure line valve 10 and flow line valve 6; Act on the gas-liquid two-phase interface from the empty gases at high pressure that inject of pipe burr; Pipe bar space forms the U-shaped pipe, and liquid level rises in the bar, and liquid is constantly discharged through flow line 11.When U-shaped space internal pressure during less than sleeve pipe 3 internal pressures, oil pipe 2 base valves 4 are opened, and the water sleeve pipe 3 spaces in gets into U-shaped pipe bar space, realization continuous gas lift.
