Embodiment 5:
Be described below in conjunction with concrete test.
Soviet Union and Eastern Europe's south gas field number at sunshine is 2700-3200 hours, and annual mean wind speed is 3.9m/s, this area's illumination and wind resource abundanter.Therefore, summer mainly utilizes solar energy, and winter makes full use of wind energy and solar energy, effectively can ensure the normal operation of intelligent injecting device.
Soviet Union and Eastern Europe South A well clump is containing 3 mouthfuls of cluster wells, and all went into operation in 2010, after downhole choke, well head oil pressure drop is to 1MPa.Current 3 mouthfuls of wells all have certain hydrops, and casing pressure fluctuation is large, and due to distance, Louis, individual well road sand, causes frother not annotate in time; After injecting frother to 3 mouthfuls of wells, because addition is comparatively large, and without supporting de-foaming process flow process simultaneously, a large amount of foam causes station inner separator gas-liquid separation effect poor, affects the operation of compressor.
Choose A well clump in June, 2013 to carry out the concentrated bubble row of many wells, concentrate froth breaking field trial, intelligent injecting device is arranged on the common monsoon upwind in well site, solid defoaming device is installed on 3 mouthfuls of well gas-collecting branch pipes.After installing solid defoaming rod additional to solid defoaming device, close 3,4# valve, open 1,2# valve.After filling it up with the frother configuring concentration to intelligent injecting device explosive box, observe liquid level sensor show value by main control panel, according to 3 implication well Production development, the working time section of corresponding injectant pump is set respectively.
When reaching first time period, automatic control column plug pump operates, and the electromagnetic valve corresponding to A1 well is opened, and frother is injected into A1 well oil jacket annular space by high pressure line, after setting-up time section terminates, and automatic control column plug pump shutdown, corresponding closed electromagnetic valve.When point being clipped to second and third time period, give A2, A3 well filling frother successively in turn.Meanwhile, by the monitoring of remote monitoring end liquid level, pressure, filling parameter and electromagnetic valve group state etc., and by sending GPRS signal, the start and stop box electromagnetic valve group switch of plunger displacement pump can be controlled, adjustment medicament filling system and parameter.When passing through solid defoaming device containing frothy natural gas, fully contacting with three groups of solid defoamings rods, realize effective froth breaking and press down bubble, preventing foam from regenerating.
(1) filling concentration
Frother filling reasonable concentration is 0.3%, and annotate after dilute with water, dilution ratio is frother: water=1:5.
(2) filling consumption
Initial stage consumption is designed to the pure frother of 10L and 40L water mixed solution, filling 500L, and the later stage adjusts according to gas well liquid loading situation; Froth breaking rod once fills it up with 3 groups, amounts to 9.
(3) effect assessment
By the tracking effect evaluation of 4 months by a definite date, result of the test shows: three mouthfuls of well day filling frother 140-150L, adding the frother cycle is 10-11 days, changing the solid defoaming rod cycle is 10-12 days, compare traditional medicine adding vehicle 4-5 days to annotate a frother, artificial successively to 3 mouthfuls of wells filling, effectively reduce staff labor intensity and shaft mouth operation risk.Meanwhile, continuous frother filling and continuous solid body froth breaking, effectively ensure that the steady production of weak spray water-producing gas well and the safety and steady of station equipment run.
Embodiment in the utility model all carries out implementation with San Koujing, but the utility model is not limited to San Koujing, can be individual well, also can many wells of right and wrong three mouthfuls.
More than exemplifying is only illustrate of the present utility model, does not form the restriction to protection domain of the present utility model, everyly all belongs within protection domain of the present utility model with the same or analogous design of the utility model.
