Abstract
The utility model discloses an automatic feeding device for foam drainage balls in a gas well. The automatic feeding device is applied to gas production in the oil-gas field, so that the foam drainage balls can be automatically fed into the well. The lower end of a cylindrical ball holding drum is connected with an electromagnetically controlled gate valve; the lower end of the electromagnetically controlled gate valve is connected with an electromagnetically controlled wall valve by a pipe; the lower end of the electromagnetically controlled wall valve is connected with the pipe; the lower end of the pipe is connected with a well mouth connection short section; a pressure-equalizing pipe is welded on the wall of pipe at the lower end of the electromagnetically controlled ball valve; the other end of the pressure-equalizing pipe is welded on the wall of the ball holding drum; the pressure-equalizing pipe is communicated with the ball holding drum and the pipe at the lower end of the electromagnetically controlled ball valve; and a sealing end cover is arranged at the top of the ball holding drum. The automatic feeding device has the effects that the foam drainage balls can be automatically fed in the gas well timely and quantificationally, therefore, the gas production cost is reduced, the working intensity of the staff is lightened, and the safety risk of operating at the well mouth is reduced. The automatic feeding device has simple structure and is easy to manufacture.
Description
Technical field
The utility model relates to oil gas field production gas technology field, and particularly gas well carries out the equipment of foaming water discharge ball draining, is a kind of gas well mouth foaming water discharge ball automatic release device.
Background technology
At present, the foaming water discharge production gas technology is a frothing capacity of utilizing surfactant, reduces in the pit shaft " slippage loss ", improves air-flow and vertically lifts the liquid ability, reaches the purpose of water pumping gas production.The foaming water discharge gas production has characteristics such as instant effect, reagent cost be low, all applies in each gas field.According to the gas well condition of production, the foaming water discharge ball just needed gas well mouth to throw in once usually every several days, therefore the gas production workman just needs often to throw in the foaming water discharge ball to well head, the nearly up to ten thousand mouthfuls of wells in gas field, every day is with manually throwing in the foaming water discharge ball, need a large amount of personnel and vehicle to cooperate, the shaft mouth operation process is loaded down with trivial details during pitching, and security risk is higher.Therefore press for a kind of device of automatic input foaming water discharge ball,, reduce the shaft mouth operation risk to reduce the gas production cost, to alleviate staff labor intensity.Along with the gas field well head is far controlled the widespread usage of electromagnetic valve, for the application of automatic ball-throwing apparatus is laid a good foundation.
The utility model content
The purpose of this utility model is: a kind of gas well foaming water discharge ball automatic release device is provided, can throws in the foaming water discharge ball automatically in gas well, reduce the gas production cost, alleviate staff labor intensity, reduce the shaft mouth operation security risk.
The technical solution adopted in the utility model is: gas well foaming water discharge ball automatic release device, mainly be connected pipe nipple with well head and form by dress ball tube, Electromagnetic Control slide valve, Electromagnetic Control ball valve, pressure-equalizing pipe, blowoff valve, it is characterized in that: cylindrical dress ball tube lower end connects an Electromagnetic Control slide valve, connects an Electromagnetic Control ball valve in the lower end of Electromagnetic Control slide valve by pipe; Lower end at the Electromagnetic Control ball valve is connected with pipe, and the lower end of pipe is connected with a well head and connects pipe nipple; On the tube wall of Electromagnetic Control ball valve lower end, be welded with pressure-equalizing pipe, the other end of pressure-equalizing pipe is welded on the dress ball barrel, pressure-equalizing pipe UNICOM dress ball tube and Electromagnetic Control ball valve lower end pipe can be directly delivered in the dress ball tube pressure in the pipe of Electromagnetic Control ball valve lower end; End cover is arranged at the top at dress ball tube.
For the hydrops in the pressure-equalizing pipe can in time be discharged, be connected with a blowoff valve in the bottom of pressure-equalizing pipe.
Summary gas well foaming water discharge ball automatic release device operating principle.Consult Fig. 1.Connecting pipe nipple 7 by well head is connected automatic release device on the well head.Close Electromagnetic Control slide valve 3, in dress ball tube 1, fill full foaming water discharge ball 2, build end cover.Pressure-equalizing pipe 5 makes the pressure maintenance balance of pressure and well head in the dress ball tube 1.Open by remote switch control Electromagnetic Control slide valve 3, foaming water discharge ball 2 drops to Electromagnetic Control ball valve 4 tops in the deadweight effect.Close Electromagnetic Control slide valve 3 then.Spool rotation by Long-distance Control Electromagnetic Control ball valve 4, when Electromagnetic Control ball valve 4 is in open mode, the foaming water discharge ball 2 of Electromagnetic Control slide valve 3 bottoms falls into the shaft bottom.Electromagnetic Control slide valve 3 regularly alternately is on off state with Electromagnetic Control ball valve 4, and foaming water discharge ball 2 drops in the well by the needs of down-hole.Foaming water discharge ball 2 mixes with formation water in the down-hole and agitates the back and bubble, and gas well resumes production after 2 hours, produces a large amount of low-density resistance aqueous foams, effectively reduces pit shaft " slippage loss " with the discharge of shaft bottom hydrops, plays the effect of foaming water discharge gas production.
The beneficial effects of the utility model: the utility model gas well foaming water discharge ball automatic release device, can self-timing, quantitatively in gas well, throw in the foaming water discharge ball, reduce the gas production cost, alleviate staff labor intensity, reduce the shaft mouth operation security risk.Simple in structure, handling ease.
