Abstract
The utility model relates to a gas well two-function medicine device, which consists of a medicine funnel, a safety valve, a pressure meter, a balance pipeline control valve, a medicine tank, an atmospheric valve, a Christmas tree bushing balance pipeline, a medicine pipeline, a medicine pipeline control valve and a Christmas tree pipe balance pipeline, wherein the top part of the medicine tank isprovided with the medicine funnel and the safety valve, and the bottom part is provided with the atmospheric valve; the bottom part of the medicine tank is respectively connected with the Christmas tree oil pipe valve and a bushing valve through a medicine pipeline, two medicine pipelines are respectively connected with the medicine pipeline control valve, two sides of the top part of the medicine tank are respectively provided with the Christmas oil pipeline balance pipeline and the bushing balance pipeline, and the two balance pipelines are respectively provided with a control valve. In thephysical principle, the height of the medicine tank is increased; by sharing the gas well oil pipes and the bushings, the thawing operation and the stoppage releasing operation can be performed by adding medicine and switching over the valves; by utilizing the device, the waste of the time and the medicine for the thawing and the stoppage releasing can be prevented, the safety of the human body can be ensured, the service life of the gas well and the valves can be prolonged, and the normal production of the gas well can be ensured.
Description
Technical field:
The utility model relates to a kind of chemicals dosing plant that is used for the de-plugging of natural gas well manufacturing process.
Background technology:
Oil gas field is in the winter time in the manufacturing process, because carrying liqs in the gas well output gas, often causes the well head production tree that the stifled or hydrate of ice takes place and stops up, because influence the gas well ordinary production.To this, on-the-spot adopt the dosing de-plugging usually, return the water mode and solve.Yet when carrying out the operation of this kind mode, operating personnel need frequent switch total valve, valve damages easily, carry out feeding operations but also will climb to the high production tree of 2m, in processing procedure, the chemical agent of pouring into is in de-plugging, and also natural gas that may be blocked sprays, there are certain potential safety hazard in personnel and equipment, ordinary production is constituted a threat to.
The utility model content:
The utility model purpose is to provide a kind of can alleviate feeding operations labour intensity, reduce the de-plugging time and medicament is wasted the dual-purpose chemicals dosing plant of gas well that also can eliminate the person and device security hidden danger.
The utility model is to realize like this, this kind chemicals dosing plant is made up of dosing funnel, safety valve, pressure meter, balance pipe line traffic control valve, grug feeding jar, atmospheric valve, production tree sleeve pipe balance pipeline, chemical feed pipe line traffic control valve, production tree oil pipe balance pipeline, and its package assembly relation is as follows: the grug feeding jar top is provided with the dosing funnel and safety valve, bottom are provided with atmospheric valve; Be connected by the dosing pipeline respectively bottom the grug feeding jar with between gas well production tree tubing valve and the sleeve valve, being hinged with respectively on the two dosing pipelines has chemical feed pipe line traffic control valve; Be respectively equipped with production tree oil pipe balance pipeline and production tree sleeve pipe balance pipeline between both sides, grug feeding jar top and the gas well production tree tubing and casing valve, be respectively equipped with the balance pipeline control valve on the two balance pipelines, on the production tree sleeve pipe balance pipeline pressure meter is housed.This device course of work is as follows:, close balance pipeline and chemical feed pipe line traffic control valve, open grug feeding jar emptying valve, after pressure meter shows that pressure is zero, close the emptying valve, in grug feeding jar, add chemical agent from the dosing funnel.In the gas well oil pipe, during dosing, open gas well mouth production tree tubing valve earlier, open oil pipe balance pipeline and oil pipe dosing by-pass valve control again, finish to OIH pipe feeding operations by efficacy of a drug action of gravity; When OIH pipe and the dosing of sleeve pipe annular space, open gas well mouth production tree sleeve valve earlier, open gas bushing balance pipeline and sleeve pipe dosing by-pass valve control earlier, finish to OIH pipe feeding operations by the medicament action of gravity.After finishing dosing, close well head production tree oil pipe and sleeve valve, close oil pipe and sleeve pipe balance pipe line traffic control valve, close oil pipe and sleeve pipe chemical feed pipe line traffic control valve, open grug feeding jar emptying valve, finish whole feeding operations.
The utility model utilization physical principle promotes the grug feeding jar height, take gas well oil pipe, sleeve pipe shared, can implement to oil pipe annular space or the oil pipe dosing de-plugging operation of thawing by switch valve, reach one jar of dual-purpose purpose, utilize this device to reduce and handle the waste of freezing stifled required time and medicament, guarantee personal safety, prolong gas well and valve application life, guarantee the gas well ordinary production.
Description of drawings:
Structural representation when accompanying drawing is the utility model work.Among the figure, label " 11 " is the gas well production tree.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is made up of dosing funnel 1, safety valve 2, pressure meter 3, balance pipe line traffic control valve 4, grug feeding jar 5, atmospheric valve 6, production tree sleeve pipe balance pipeline 7, dosing pipeline 8, chemical feed pipe line traffic control valve 9 and production tree oil pipe balance pipeline 10.Wherein, grug feeding jar 5 is installed on the cement platform that overhead 2m is high, dosing pipeline 8, dosing funnel 1, safety valve 2, pressure meter 3, production tree sleeve pipe balance pipeline 7, production tree oil pipe balance pipeline 10 are connected on the grug feeding jar 5, and balance pipeline 7,10 and dosing pipeline 8 are connected to well recovery tree oil pipe and sleeve valve joint by by-pass valve control 4,9.
