The utility model has the advantages of reasonable design, advanced technique, high transmission and collection precision for water injection pressure and flow, stable control, safety and reliability, realizing 24h steady flow or steady pressure control automatically, higher stability and anti-interference capability, in addition the utility model has manual control means besides automatic remote distance control function.
Description
Technical field
The utility model relates to a kind of oil-field flooding control device, particularly relates to a kind of skid-mounted type oil field intelligence current stabilization water distribution valve group.
Background technology
Oil field flood pattern generally is made up of water flooding pump station, water injection valve pond, distributing room for water injection, water injection well and surface line.Distributing room for water injection and water injection well directly link, and are the key links that realizes stable yields control water.Domestic water injection technology mainly adopts the Artificial Control mode at present, and mostly the high-pressure control valve that the oil field distributing room for water injection uses is the gate valve of manual adjustment, regulates effort, consuming time, and regulating pondage is difficult to grasp; Valve seat is easily stifled, Yi Ka or be not closed completely, and application life is very short.From the mode of occupation at scene, the water meter existing problems are also more, and error in dipping is big, and material consumption is serious.When power network fluctuation or dry-pressing fluctuation, influence water injection rate.Night particularly, because pressure oscillation, the workman can not in time find and regulate, and causes water filling out of control, when dry-pressing is low in addition appearance " pour in down a chimney " phenomenon, cause and shake out, have a strong impact on the stable exploitation in oil field, increase workover cost.At present, every mouthful of water injection well on the oil field all is equipped with equipment such as high pressure valve, pressure meter and flow meter.These equipment exist many unreasonable and unsafe factors in actual production, mainly show the following aspects: (1) is because the high pressure valve of control water filling mostly is gate valve or stop valve, valve causes wearing and tearing because of open and close, particularly under the big situation of pressure reduction, easily cause seal failure, seepage takes place, even the accident that screw mandrel flies out and hurts sb.'s feelings or damage equipment occurs.Therefore the valve replacement cycle only is 1 year, even shorter; (2) all more than 15Mpa, part oil-field flooding pressure surpasses 40Mpa to most of oil-field flooding pressure, and manual adjustment is absolutely unsafe; (3) because power network fluctuation or water flooding pump station occur unusually, can cause the fluctuation of water injection well pressure, cause that sometimes waterflood-transmission line breaks, if operating personnel can not in time find, then can damage production equipment, influence normally carrying out of water filling work; (4) since manually operated time lag effect, can not in time handle the abnormal conditions that water filling occurs, especially at night, because pressure oscillation, the workman can not in time find and make corresponding processing, then can cause the out of control or water injection well of water injection well " to pour in down a chimney ", the water injection well that causes that has shakes out, and this phenomenon has a strong impact on the stable exploitation and the safety in production in oil field; (5) water injection well injection flow manual adjustment, program is cumbersome, because geology dynamically allotment is frequent, fractional water flooding station output and actual water injection rate do not match, it is big that pumping plant is returned flow, causes energy dissipation, and pressure reduction is big before and after the return valve, cause return valve short application life, thereby increased the operating cost of pumping plant.
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, but the skid-mounted type oil field intelligence current stabilization water distribution valve group of a kind of reasonable in design, advanced technology automatic control flow and security of operation is provided.
The technical solution of the utility model is: a kind of skid-mounted type oil field intelligence current stabilization water distribution valve group, comprise water filling house steward 1 who is connected with water pump and the distribution pipe 2 that is connected with water filling house steward 1, pressure meter 3 is installed on the water filling house steward 1, it is characterized in that: total gate valve 6 and strainer 5 are installed between water filling house steward 1 and distribution pipe 2; Be positioned at and be connected with an arm that is connected with water injection well 7 on the distribution pipe 2 at least, arm gate valve 8 and high pressure flow auto-controller 9 are installed on the arm 7.
The utility model compared with prior art has the following advantages: the utility model is reasonable in design, and advanced technology has computer 485 interfaces, can realize remote control, carries out data acquisition, analyzes water injection pressure; Flow becomes and to send the acquisition precision height, and control steadily, and is safe and reliable, realizes 24 hours current stabilizations or voltage stabilizing control automatically; The valve group has advantages of higher stability and antijamming capability, except that having automatic control function, also possesses manual control mode; The field shows, can effectively reduce the workload of manual adjustment valve, makes the water injection rate held stationary; At oil pressure during less than the water injection well starting pressure, system can realize that also valve closes automatically, avoids oil reservoir to return and tells, and guarantees the safety in production of water injection well.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises water filling house steward 1 who is connected with water pump and the distribution pipe 2 that is connected with water filling house steward 1, and pressure meter 3 is installed on the water filling house steward 1, and total gate valve 6 and strainer 5 are installed between water filling house steward 1 and distribution pipe 2; Be positioned at and be connected with an arm that is connected with water injection well 7 on the distribution pipe 2 at least, arm gate valve 8 and high pressure flow auto-controller 9 are installed on the arm 7.
Be positioned on the arm of high pressure flow auto-controller 9 water outlets one side pressure meter 3 is installed.
The flow meter of high pressure flow auto-controller of the present utility model partly adopts impeller, axle and the bearing through specially treated to constitute.The on-the-spot sewage in oil field is had very strong good antiscale property function, and described impeller bracket assembly is easy to take out in watchcase, brings great convenience for the periodic verification work of flow meter.Flow-control has alternating current generator to drive and manual two kinds of patterns.When having a power failure, but flow meter because internal cell power supply operate as normal is arranged, but this moment the manual adjustments valve because the effect handwheel of deceleration device is very light, the resolution ratio of adjusting is very high.
