Description
Technical field
The utility model relates to the technology that drives a well of abnormal pressure gas well, particularly a kind of abnormal pressure gas well system that drives a well.
Background technology
The mode of driving a well mainly contains two kinds at present: first kind is to utilize the big discharge capacity of fracturing unit truck in well, to inject clear water; In pit shaft, set up fluid column and reduce the well head oil pressure; When well head pressure drops to a certain degree, after the satisfied condition that drives a well, drive a well through manual work or automatic control valve; Second kind be through hydraulic test pump only to the water filling of high pressure flow process section, and when boosting near the well head pressure, drive a well through the remote auto control valve.
Above-mentioned first kind of mode of driving a well can satisfy the needs that drive a well at present; But the scene needs fracturing unit truck, has increased cost of production, and it is consuming time longer to drive a well simultaneously; And drive a well instead arrange after, still still have high velocity air and the impurity that carries to the erosion problem of high pressure throttling with bend part; Second kind of mode that drives a well can satisfy the needs that drive a well basically, but have high velocity air and the impurity that carries to the erosion of high pressure throttling with bend part, throttle effect forms hydrate and stops up, and can only take automatic control valve to drive a well.
The utility model content
The utility model addresses the above problem the abnormal pressure gas well system that drives a well that provides; Through hydraulic test pump a further refinement of the mode that drives a well to high pressure flow process fluid injection body; Not only cost is lower than first kind of mode that drives a well; And solved high velocity air and the impurity that carries to erosion problem and the hydrate blockage problem of high pressure throttling with bend part, improved the efficient that drives a well greatly simultaneously, reduced operating personnel and high-tension apparatus risk.
The utility model technical scheme is following:
The abnormal pressure gas well system that drives a well; It is characterized in that: comprise christmas tree with the supporting high pressure gas production manifold platform that is connected of christmas tree; High pressure gas production manifold platform comprises thermometric pressure measurement cover, valve cover, valve and medicament dispenser pump; Christmas tree directly is connected with thermometric pressure measurement cover, and thermometric pressure measurement cover is connected with valve with the valve cover that cover connects, and valve cover and the valve that cover connects is connected the thermometric pressure measurement cover of N serial connection, valve cover and the valve that cover connects again; The valve cover that last cover connects is connected a thermometric pressure measurement cover again with the rear end of valve, and last thermometric pressure measurement cover back connects the flap type that surges; Said first thermometric pressure measurement puts and connects the medicament dispenser pump;
Said first thermometric pressure measurement puts and connects the medicament dispenser pump.
Said medicament dispenser pump is the dispenser pump of water and ethylene glycol mixture.
The principle of the utility model is:
Utilize the weak compressibility and the antifreeze characteristic of ethylene glycol of water and ethylene glycol; Employing medicament dispenser pump is filled with water and the ethylene glycol mixture that mixes by a certain percentage and is forced near the well head oil pressure between flap type and christmas tree flutter valve to surging; Open the christmas tree valve then, treat directly to open the Long-distance Control hydraulic operated valve after the pressure stability, reach the purpose that drives a well through long-range pilot operated valve device front level Four throttling open flow; If carry mud secretly in the natural gas in the well; Can continue filled with water and ethylene glycol mixtures in the high pressure flow process through the medicament dispenser pump,, directly annotate clear water and get final product to inlet if flow process temperature water under high pressure compound generates temperature.
The effect of the utility model is following:
The utility model has overcome that the manual work of high pressure operating mode lower valve is difficult to open and throttle effect forms the hydrate blocking problem easily; Reduce moment high velocity air and the impurity that the carries erosion effect that can produce throttling position and bend part, reach the safe and efficient purpose that drives a well.
Attaches key diagram
Fig. 1 is the structural representation of the utility model
Wherein, Reference numeral is: 1 christmas tree, 2 high pressure gas production manifold platforms, 3 thermometric pressure measurement covers, valve cover and valve that 4 covers connect, 5 medicament dispenser pumps, 6 flap types that surge.
The specific embodiment
As shown in Figure 1; The abnormal pressure gas well system that drives a well; Comprise christmas tree 1 with the christmas tree 1 supporting high pressure gas production manifold platform 2 that is connected, high pressure gas production manifold platform 2 comprises thermometric pressure measurement cover 3, valve cover, valve and medicament dispenser pump 5, christmas tree 1 directly overlaps 3 with the thermometric pressure measurement and is connected; Thermometric pressure measurement cover 3 is connected with valve 4 with the valve cover that cover connects; Valve cover and the valve 4 that cover connects is connected the thermometric pressure measurement cover 3 of N serial connection, valve cover and the valve 4 that cover connects again, and the valve cover and the rear end of valve 4 that last cover connects is connected a thermometric pressure measurement cover 3 again, and last thermometric pressure measurement cover 3 back connects the flap type 6 that surges;
Connect medicament dispenser pump 5 on said first thermometric pressure measurement cover 3.
Said medicament dispenser pump 5 is the dispenser pump of water and ethylene glycol mixture.
Native system utilizes the weak compressibility and the antifreeze characteristic of ethylene glycol of water and ethylene glycol; Adopt medicament dispenser pump 5 to fill with water and the ethylene glycol mixture that mixes by a certain percentage to surging between flap type 6 and christmas tree 1 flutter valve and be forced near the well head oil pressure; Open christmas tree 1 valve then, treat directly to open the Long-distance Control hydraulic operated valve after the pressure stability, reach the purpose that drives a well through long-range pilot operated valve device front level Four throttling open flow; If carry mud secretly in the natural gas in the well; Can continue filled with water and ethylene glycol mixtures in the high pressure flow process through medicament dispenser pump 5,, directly annotate clear water and get final product to inlet if flow process temperature water under high pressure compound generates temperature.
Adopt native system that the abnormal pressure gas well has been carried out the inferior The field of 8 wells; Abnormal conditions such as throttling element, elbow thorn is bad, hydrate obstruction all not taking place, satisfied the requirement that safety drives a well, has shortened the operating time that drives a well simultaneously; Reduced cost of production, effect of field application is better.
