Abstract
The utility model provides a be applied to gas lift valve in oil and gas field gas-liquid technology, including bellows subassembly (1), single current valve (2), lower valve body (3), well valve body (4), valve ball (5), disk seat (6), tail stifled (7), single current valve (2) are equipped with to the bottom of the device, be equipped with valve ball (5) between lower valve body (3) and well valve body (4), valve ball (5) are located on disk seat (6), install bellows subassembly (1) on the upper portion of valve body, tail stifled (7) are equipped with at the top of the device, be fit for the well of gas lift process condition, when carrying out the acidizing, when operations such as fracturing, can use same tubular column, in time discharge liquid, guarantee the pressure resistance of gas lift valve, thereby ensure that gas lift process is successful and oil gas well resumes production.
Description
Technical field
The utility model is a special-purpose gaslift instrument that is applied in the gas-liquid technology of petroleum gas field, specifically, is a kind of gas lift valve.
Background technology
Adopt injection natural gas, liquid nitrogen/nitrogen gas to carry out lifting, get rid of the oil/water in oil/gas-water well, thereby the extraction oil/gas is one of best process of economic benefit in the modern oil recovery/water pumping gas production process, injecting gas can go deep in the liquid by gas lift valves at different levels from top to bottom one by one, the above liquid weight in oil pipe bottom is lightened, and reduction is produced thereby assurance oil/gas well is continuous smoothly the back pressure of payzone.
For the well that is fit to the gaslift process conditions, when the oil gas well carries out acidifying, pressing crack construction, if utilize gas lift string to join work, gas lift valve malposition high pressure then may appear, cause gas lift valve to damage easily, thereby cisco unity malfunction causes the failure of gaslift technology, causes unnecessary economic loss.
And present domestic gas lift valve proof to external pressure generally is no more than 50MPa, and it is to implement conventional gaslift technology and the gas lift valve developed at the oil gas well, is not suitable for acidifying, fracturing work.
Summary of the invention
The purpose of this utility model is to provide a kind of gas lift valve, it is fit to the well of gaslift process conditions, when carrying out operations such as acidifying, pressure break, can use same tubing string, in time discharge liquid, guarantee the withstand voltage properties of gas lift valve, thereby guarantee that success of gaslift technology and oil gas well resume production, and can provide bigger proof to external pressure performance simultaneously.
The utility model is achieved in that and comprises bellows component 1, ball-and-seat 2, following valve body 3, middle valve body 4, valve ball 5, valve seat 6, tail stifled 7, ball-and-seat 2 is equipped with in the bottom of this device, between following valve body 3 and the middle valve body 4 valve ball 5 is housed, valve ball 5 is located on the valve seat 6, on the top of valve body bellows component 1 is installed, tail stifled 7 is housed at the top of this device.
Bellows number 〉=1 in the bellows component 1, and the single independence of bellows.
Advantage of the present utility model is: be fit to the well of gaslift process conditions, when carrying out operation such as acidifying, pressure break, can use same tubing string, in time discharge liquid, guarantee the withstand voltage properties of gas lift valve, thereby guarantee that success of gaslift technology and oil gas well resume production.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, form by bellows component 1, ball-and-seat 2, following valve body 3, middle valve body 4, valve ball 5, valve seat 6, tail stifled 7, ball-and-seat 2 is equipped with in the bottom of this device, between following valve body 3 and the middle valve body 4 valve ball 5 is housed, valve ball 5 is located on the valve seat 6, on the top of valve body bellows component 1 is installed, tail stifled 7 is housed at the top of this device.Bellows number 〉=1 in the bellows component 1, and the single independence of bellows.The utility model is a kind of built-in bellows gas lift valve, external diameter 1in (Φ 25.4mm), its bellows (single integral body, non-two root beads connect) internal pressure-resistant 15MPa (filling nitrogen pressure), proof to external pressure 90MPa.Gas lift valve 100TGP1190MPa technical data is as follows
Gas lift valve technology 100TGP11 parameter list
