Description

Oil pumper well head assembled valve

The utility model relates to oil-field oil pumper well head assembled valve.

Along with Oilfield developing, strata pressure descends gradually, and in order to improve recovery ratio, the Oilfield using that has to the recovery scheme of underground flooding, is lifted oil raising recovery ratio to reach water while exploiting; Because the oil flow that contains wax in the oil and have is relatively poor, be located in the oil field of cold district, in order to guarantee the ordinary production of oil well, on well head, take multinomial measure, be furnished with the different process flow process on the production tree and could satisfy production requirement.Shown in accompanying drawing one, it is that hotwater tracing's well head process chart is mixed in the oil field that has at present.The accompanying drawing upper left side is a production tree, in the double dot dash line of right side be can realize fuel-displaced flow process, mix the hot water flow process, level pressure venting flow process, well-flushing flow process and profit be communicated with flow process.Each process-oriented layout disperses, and floor space is big, is awkward and manages, in the winter time also inconvenience insulation.

The purpose of this utility model is to avoid the weak point in the present technology, and a kind of various flow processs and low oil pumper well head assembled valve of compact in design cost realized is provided.

The purpose of this utility model can reach by the following technical programs; Produce sample valve, pressure gauge valve and the delivery valve that connection is housed on the pipeline in the technological process of well head production tree, pick out oil pipe on the delivery valve; On technological process well-flushing pipeline, be connected to the combination valve of connection, be shaped on flushing valve, flap valve, valve discharging gas under certain pressure on the combination valve and mix the hot water bypass valve, mix the hot water bypass valve and be communicated with formation one assembled valve with fuel-displaced pipe on the above-mentioned delivery valve with pipe.Wherein between flushing valve and the flap valve connected chamber is arranged, flap valve and mix between the hot water bypass valve connected chamber is arranged, mixing between hot water bypass valve and the level pressure stop valve has connected chamber; Between level pressure stop valve and the valve discharging gas under certain pressure connected chamber is arranged, be connected to blowoff valve with pipe on the flap valve.Above-mentioned each valve cooperates by pipe can realize the different process flow process of producing, since compact between each valve body, can realize the design's purpose.

The utility model is compared with above-mentioned prior art can have following effect: control valve is assembled into one on each flow process of oil pumper well head owing to make, for satisfying technological requirement, cavity or pipeline are arranged between each valve, the mouth of pipe that different purposes are arranged on the valve connects other pipeline on each technology at the scene, the convenient installation and operation, save raw material, also convenient management, floor space is little, also is convenient to insulation in the winter time.

Accompanying drawing 10 is that Fig. 3 is the plane flow graph that can realize mixing hot water bypass flow process and workover treatment.

Below in conjunction with accompanying drawing will the utility model is described in further detail:

By accompanying drawing 3 in conjunction with shown in Figure 4, the technological process of oil-field oil pumper well head production tree has the pipeline of production 15 well-flushing pipelines 22 and the not control valve of same-action (3-14) is arranged, the utility model is on production pipeline 15 sample valve 3 of connection, the valve 4 and the delivery valve 5 of controlled pressure table to be housed, make three valves (3-5) concentrate on to produce on the pipeline 15 and form combinaing valve body, wherein valve 5 is connected to fuel-displaced pipe 16; On well-flushing pipeline 22, be connected to the combinaing valve body 2 of connection, be shaped on flushing valve 6, flap valve 7, valve discharging gas under certain pressure 8, level pressure stop valve 9 on the combinaing valve body 2 and mix hot water bypass valve 10; Mix hot water bypass valve 10 usefulness pipes 20 and be communicated with formation one assembled valve with fuel-displaced pipe 16, volume is little in light weight, saves raw material.Wherein between the valve (6,7) connected chamber 21 is arranged, as shown in Figure 6; Valve has connected chamber 19 between (7,10), as shown in Figure 5; Valve has connected chamber 26 between (10,9), and valve has connected chamber 25 between (9,8), as shown in Figure 7; Valve 7 upper connecting tube 18 are equipped with blowdown relief valve 13, as shown in Figure 5 on the pipe 18.

Feedwater main valve 11 also is housed on the above-mentioned pipe 18, connects water service pipe 17 on the main valve 11.By shown in Figure 7, valve 8 usefulness pipes 24 are communicated with arbitrage pipeline 23.By shown in Figure 6, valve 6 is communicated with well-flushing pipeline 22, is communicated with arbitrage pipeline 23, wherein an end of pipeline 22 dress relief valve 14 again; On pipeline, adorn the valve 12 of controlled pressure table simultaneously.

The going into of above-mentioned each valve, discharge connection can be finished the different process flow process.Shown in accompanying drawing 8, can finish fuel-displaced flow process through valve 5 by fuel-displaced pipe 16 by producing pipeline 15; Go into valve 11 by water service pipe 17, go into valve 7, go into valve 10, converge to form by pipe 20 and fuel-displaced pipe 16 and mix hot water bypass flow process through cavity 19 through pipe 18; By cover header 23, through air inlet pipe 24, go into valve 3, go into valve 9 through cavity 25, converge through cavity 26, pipe 20 and fuel-displaced pipe 16, converge and form level pressure venting flow process.By shown in Figure 9, go into valve 11 by pipe 17, go into valve 7 through pipe 18, go into valve 6 through cavity 21, go into the arbitrage pipeline through the well-flushing pipeline and form the well-flushing flow process.By shown in Figure 10, go into valve 11 by pipe 17, go into valve 7 through pipe 18, go into valve 10 through pipe 19, by pipe 20 and fuel-displaced pipe 16 converge can form another approach mix hot water bypass flow process.Because above-mentioned flow process is not to carry out simultaneously, so but some valve and pipeline one after the other are used.
