Description

A kind of collector-shoe gear
Technical field
The utility model relates to displacement of reservoir oil field, oil field, relates in particular to a kind of collector-shoe gear.
Background technology
At present, oil extraction in oil field generally adopts the Injection Well oil production method that matches with producing well.During Injection Well recovers the oil, generally injected water need to be injected in oil reservoir, by injected water in oil reservoir to oily driving effect, oil is able in producing well extraction.
Viscosity is a kind of physical attribute of fluid, in order to weigh the viscosity of fluid.If have relative motion between object and fluid, between object and fluid, because fluid viscosity effect will produce frictional force, described frictional force is used for stoping the relative motion between object and fluid.
Because injected water oneself viscosity is low, and then it is little that injected water arrives the frictional force producing after oil reservoir, and described frictional force generally cannot stop the relative motion between injected water and oil reservoir.Like this, injected water is easy to just be lost in the hole of oil reservoir, finally causes injected water to drive poor effect to the oil in oil reservoir, affects field output.For improving the viscosity of injected water, generally adopt now injected water to arrive the before middle mixed polymer solution of Injection Well to improve viscosity of injected water, the mixed liquor of injected water and polymer solution, because viscosity is relatively high, is difficult for running off in oil reservoir like this.Described polymer solution generally adopts the high molecular weight water soluble polymer of polyacrylamide (PAM) class, and the characteristic of this type of source of polymer on molecular structure, by mixing the viscosity that can improve injected water with injected water.But described polymer is easily degraded in flow process as while being subject to the active forces such as shearing, and oneself viscosity can reduce.At present, in field produces, before injected water arrives Injection Well, normal use collector-shoe gear forms mixed liquor during polymer solution is blended into injected water, more described mixed liquor is drained in Injection Well pipeline.
Fig. 1 is conventional at present a kind of threeway collector-shoe gear.As shown in Figure 1, described threeway collector-shoe gear comprises injected water input pipe 100, polymer input pipe 200, efferent duct 300.Described injected water input pipe 100 is for inputting injected water, and injected water input pipe 100 bottoms connect efferent duct 300 one end and polymer input pipe 200 one end.Injected water input pipe 100, polymer input pipe 200, efferent duct 300 are connected to each other formation " T " character form structure.Injected water input pipe 100 is positioned in same pipeline axis with efferent duct 300.Efferent duct 300 other ends connect mixed liquor export pipeline 400, for mixed liquor being drained into mixed liquor export pipeline 400.Described polymer input pipe 200 is for inputting polymer solution, and the pipeline axis of the pipeline axis of polymer input pipe 200 and injected water input pipe 100 is orthogonal, and injected water input pipe 100 forms right angle vertical relation with polymer input pipe 200 intersections.Injected water input pipe 100 one end and polymer input pipe 200 one end are connected to form liquid intersection, and the mixed liquor forming in intersection is drained into the mixed liquor export pipeline 400 being attached thereto by efferent duct 300.
In above-mentioned prior art, because injected water input pipe 100 is right angle vertical relation with polymer input pipe 200 intersections, this just causes between polymer solution and injected water is vertical remittance.And then injected water forms one along the downward shear force of injected water input pipe 100 axis to polymer solution when by intersection, described shear force can cause the viscosity of polymer solution to incur loss in injected water and polymer solution mixed process.
