Abstract
The utility model relates to a flow regulator which is used for regulating the flow of the aqueous solution of Newton pseudoplastic liquid PAM (polyacrylamide), under the condition of little quantity of degraded stickum. In the regulator, a pipe coil (8), a main pipe (2), sub pipes (9) are installed on a main body (7); opposite operating type ball valve (4) is arranged on a main pipe; a cutting sleeve ball valve (3) is installed on each of the sub pipes (9); simultaneously, a transition connector (5) is installed on each sub pipe (4). Different flow can be generated, with one device-the utility model, under the condition of the least viscosity reduction. Therefore, the requirement of manufacturing technique is satisfied. Thus, the flow regulator is an ideal device for flow regulation for an injection well in the tertiary oil recovery of an oilfield.
Description
The utility model relates to the improvement invention of Flow-rate adjustment or part flow arrangement, is that a kind of oilfield is used for non newtonian pseudoplastic behavior liquid---PAM(polyacrylamide) aqueous solution device that under the minimum condition of viscosity reduction, carries out Flow-rate adjustment or shunting.
In the prior art, single current amount coil pipe damper is had at Dagang Oilfield in Japanese MCY company.Because it can only satisfy a kind of flow, when needs change flow, must use an other dish coil pipe instead, a pipe dish has only a resistance, a kind of flow, can not regulate, and brings very big difficulty for production run and management.
In view of the problem that known technology exists, the purpose of this utility model is to provide a kind of and can reduces under the minimum condition in viscosity, regulates to produce different flows, different pressure, thereby satisfies the needs of production technology.
The utility model is that following mode is finished, and adopts long coil pipe to produce on-way resistance, fall thereby reduced viscosity, and on the body of adjuster, be provided with differential pressure indicator, pressure lead-in wire, female pipe and son pipe, on mother's pipe and each sub-pipe, all be provided with ball valve and concentric reducer.Because permutation and combination is carried out in the many places tap in the middle of long coil pipe, thereby has produced numerous different resistances, promptly produced numerous flows, reach the purpose of regulating flow.
In order to reduce the viscoelastic deformation of the PAM aqueous solution, be provided with the tangent line tap at the coil pipe import and export, pass in and out female pipe place at the child pipe and be equipped with concentric reducer, to reduce the shearing viscosity reduction of viscoelastic deformation, flow velocity control in concentric reducer and the coil pipe is all by different liquids, and the restriction of the shear rate of variable concentrations is determined.
The utility model is compared with known technology, has the following advantages, and the utility model can the many wells of a pump, the PAM water under high pressure solution that pumps carries out transferring to each water injection well after the Flow-rate adjustment, measuring pump replaces with plunger displacement pump, and the platform number of pump significantly reduces, and has overcome the flow process of boosting of a measuring pump of present every mouthful of water injection well, reduced investment, dwindled plant area, reduced construction costs, can also become fixed pump station with this product simultaneously and be movable pumping plant, be convenient to resettlement, improved the utilization rate of pumping plant.
The utility model has following accompanying drawing
Fig. 1 is a structure principle chart of the present utility model
Fig. 2 is an elevation of the present utility model
Fig. 3 is the A-A sectional view of Fig. 2
Fig. 4 is the B-B sectional view of Fig. 2
Fig. 5 is a concentric reducer structure chart of the present utility model
Accompanying drawing has been represented structural principle of the present utility model and embodiment, describes the relevant details of embodiment below more in conjunction with the accompanying drawings.On body of the present utility model (7), be provided with differential pressure indicator (1), coil pipe (8), female pipe (2) and son pipe (9), on mother's pipe (2), be provided with wafer type ball valve (4), on each strip pipe (9), be provided with cutting ferrule ball valve (3), and on each sub-pipe, be provided with concentric reducer (5), the solution adjuster that employing is produced with the utility model design motif, will bring positive result of use to petroleum chemical industry, now can illustrate.Annotate the PAM aqueous solution as the oil field, existing 25 mouthfuls of wells with every well one pump flow process, 25 measuring pumps, and other adds 9 of stand by pumps, and totally 34 pumps add miscellaneous equipment, and capital equipment takes more than 300 ten thousand yuan of needs, more than 12 ten thousand yuan of every well average costs.As adopt this product, and under equal conditions, only need 2 plunger displacement pumps, replaced 34 measuring pumps, add this product and other installation cost, only need more than 240 ten thousand yuan, every well investment is on average less than 100,000 yuan.Therefore the solution adjuster of each Oilfield using the utility model design motif will produce positive result of use and good economic benefit.
