Abstract
The utility model relates to a uniflow valve assembly of gas injection for a sound wave, which belongs to the technical field of a technical device of nitrogen injection for gas lift and liquid discharge in an oil and gas well and comprises a gas injection joint, an isodiametric tee joint, a uniflow valve, a vent valve and a connecting pipe nipple, wherein threads are respectively arranged at both ends of the gas injection joint, one end is connected with a well head, and the other is connected with the isodiametric tee joint; cylindrical hollow cavities which are respectively a jet cavity, an oscillation cavity and an amplification cavity are sequentially aligned in a step type in the gas injection joint, and a bell mouth is processed at the gas inlet end of the jet cavity. In a construction process of the nitrogen injection for the gas lift, the gas injection joint can generate the sound wave which acts on well liquid in the construction well to take the cavitation effect and the mechanical vibration effect so that the well liquid generates gas bubbles to decrease the viscosity of the well liquid, improve the flowing state, shorten the construction time, and increase the construction efficiency of the gas lift.
Description
Technical field: the utility model relates to a kind of sound wave gas injection ball-and-seat assembly, belongs to the oil gas well and annotates nitrogen act discharge opeing technique device technical field.
Prior art: existing gas injection ball-and-seat assembly is by gas injection joint, equal tee, ball-and-seat, atmospheric valve, parts such as connection pipe nipple connect fastening composition, gas injection joint inside is processed with an isometrical through hole, in the gaslift work progress, high pressure nitrogen is by isometrical through hole and inject into well, the expansion energy that utilizes high pressure nitrogen is with liquid lifting in the well and discharge pit shaft, owing to reason such as Partial Jobs well liquid level height or well fluid viscosity be big, the well liquid velocity of discharge is slow, not only the gaslift activity duration is long, to such an extent as to and the part well liquid in the high indivedual wells of kick off pressure is clamp-oned the stratum by high pressure nitrogen, cause the gaslift weak effect, influenced the production of oil gas well.
Summary of the invention: the purpose of this utility model provides a kind of sound wave gas injection ball-and-seat assembly, and is slow with the well liquid velocity of discharge that overcomes prior art, and the defective of the production of oil gas well is grown, influenced to the gaslift activity duration.
The utility model is made up of gas injection joint, equal tee, ball-and-seat, atmospheric valve, connection pipe nipple, be respectively equipped with connecting thread at the gas injection joint two ends, one end and well head connect, the other end and equal tee connect, gas injection joint is inner to be the stepped cylindrical cavity that is arranged in order, be respectively spray chamber, vibration chamber and enlarged cavity, be processed with a horn mouth at the inlet end of spray chamber.
In annotating nitrogen act work progress, the horn mouth of the inlet end of the spray chamber in the gas injection joint, vibration chamber, enlarged cavity and spray chamber can produce sound wave, acoustic wave action well liquid in the construction well produces cavitation and mechanical oscillation effect, make well liquid produce bubble, reduce the well fluid viscosity, improve flow regime, reduce well liquid when up with well in the frictional resistance of tubing string generation; Under the promotion of high pressure nitrogen, well liquid can flow with fast speeds and go upward to well head and discharge pit shaft, reaches the reduction kick off pressure, shortens the engineering time, improves the purpose of gaslift efficiency of construction simultaneously.
Description of drawings: accompanying drawing 1 is the utility model structural representation.
The specific embodiment: as can be known by accompanying drawing 1, the utility model is made up of gas injection joint 1, equal tee 2, ball-and-seat 4, atmospheric valve 6, connection pipe nipple, gas injection joint 1 two ends are respectively equipped with connecting thread, one end and well head connect, the other end and equal tee 2 connect, gas injection joint 1 is inner to be to be respectively spray chamber 9, vibration chamber 10 and enlarged cavity 11 by the stepped cylindrical cavity that is arranged in order, and is processed with a horn mouth 8 at the inlet end of spray chamber 9; The upper end of equal tee 2 connects by a threaded reducing pipe nipple 7 and atmospheric valve 6, and the outlet side of the air-inlet of equal tee 2 and ball-and-seat 4 connects by a threaded pipe nipple 3; The air-inlet of ball-and-seat 4 and a double thread pipe nipple 5 connect.
Before the gas injection construction, gas injection joint 1 of the present utility model is installed in the gas-lift well well head, the gas injection pipeline is connect with sound wave gas injection valve assembly by the short knot 5 of double thread, at this moment, the atmospheric valve 6 on head valve and the sound wave gas injection valve body assembly should be in closed condition.When beginning gas injection gaslift construction; open head valve; the high pressure nitrogen that the nitrogen making and injection device produces is through the connection pipe nipple 5 in the sound wave gas injection valve assembly; ball-and-seat 4; connect pipe nipple 3; equal tee 2 enters gas injection joint 1; high pressure nitrogen is by the horn mouth 8 in the gas injection joint 1; form turbulent condition; by spray chamber 9 time, produce strong sound; and in the 10 interior resonances enhancing of vibration chamber; form sound wave; sound wave produces cavitation through well liquid in 11 pairs of construction wells of enlarged cavity; when nitrogen making and injection device emergency shutdown situation occurring, when operating personnel had little time to close head valve, sound wave gas injection ball-and-seat assembly can play and prevent that high pressure nitrogen from returning and scurry and the effect of impact device.
When gaslift construction end, need close head valve earlier, open the atmospheric valve 6 on the sound wave gas injection valve assembly again, drain the high pressure residual air in the valve body, remove then and the gas injection pipeline that connects pipe nipple 5 connections, at last sound wave gas injection valve assembly is pulled down from well head.
