Description
Relate to the field
The utility model relates to a kind of equipment that matches with the blending equipment of fracturing truck group in the on-the-spot pressing crack construction process in oil field, specifically, is the continuous sand delivering car of oil field compression fracture.
Background technology
At present domestic in fracturing process, a whole set of unit is made up of measuring truck, pump truck, blending equipment, sanding vehicle, tank car.Blending equipment need continuously be supplied with its liquid, sand and other additive in the fracturing process, reach certain viscosity number by being mixed after, by pump truck the mixing material that these reach certain viscosity is squeezed in the well with very high pressure, the stratum is pressed off.After the sand that contains liquid was pressed in the well in the crack of stone, the sand of crude oil from the seam of lithostratigraphy flowed into (sand proppant effect in the rock seam at this moment) in the well, to increase crude oil yield.Reach above effect, the best way is that liquid, additive and sand add blending equipment continuously with certain proportion, is pressed into the down-hole by after being mixed.But in the pressure break site operation process, sand is to be added in the mulling bucket of people's blending equipment by 8 side's sanding vehicles at present.As in the fracturing process as need 30 side's sands, just need 4 defeated cars to transport.After first is input to the mulling bucket with sand, wait this car to withdraw from after the fork-like farm tool used in ancient China, second car is poured into again, after so circulation is mixed sand by blending equipment, is squeezed into by pump truck and to carry out pressure break in the oil well.With regard to producing a problem, add in the sand process to blending equipment exactly in this process, it is discontinuous to occur adding sand, and generation a period of time does not have sand adding blending equipment and liquid is mixed.So just can not reach best fracturing effect.Owing to add the discountinuity of sand, site operation can't carry out according to the preferred parameter of optimal design, average sand ratio is about 30～40%, there is big gap with external advanced level, because average sand is lower, causes the pressure break subject word shorter, producing energy is employed insufficient, thereby have influence on the pressing crack construction effect, increased the risk of sand plug simultaneously.External HALLIBURTON and DOWEL company develop the massive hydraulic fracturing sand conveyor installation respectively, but its finished product costliness, and scale is big, the practical application that incompatibility is domestic, and at present, domestic still do not have a this pressure break sand conveyor installation with actual application value
Technology contents
The purpose of this utility model is to provide a kind of oil field that can effectively solve can not reach in pressing crack construction process and add sand continuously, causes the problem of the desirable incremental oil production output of fracturing effect out of reach and realizes adding continuously the continuous sand delivering car of purpose oil field compression fracture that sand, control and metering add sand.
The utility model is achieved in that and comprises delivery headstock 2, semi-trailer 3, diesel engine 4, hydraulic power source 5, horizontal belt machine 6, door control 7, tight flask 8, sandbox 9 hoists, sediment transport pipe 10, inclination belt feeder 11, metering unit 12, hydraulic actuating cylinder 13, tilt stand 14, delivery headstock 2 is connected with semi-trailer 3, diesel engine places on the semi-trailer 3, hydraulic power source 5 connects with diesel engine 4, on semi-trailer 3, be provided with horizontal belt machine 6, tight flask 8, hoisting has sediment transport pipe 10 on the sandbox 9, afterbody at this device is equipped with inclination belt feeder 11, metering unit 12 is arranged on the inclination belt feeder 11, tilt stand 14 is installed on the semi-trailer 3, and hydraulic actuating cylinder 13 places on the tilt stand 14.
The utility model also adopts following technical scheme:
The sand delivering car rear portion has been equipped with two and has received the arm oil cylinder.
The inclination belt feeder 11 that stretches out can be 18 °～90 ° rotations.
Advantage of the present utility model is: this device is adopted the form of loading with car, conveniently moving, can effectively solve the oil field and in pressing crack construction process, can not reach and add sand continuously, cause the problem of the desirable incremental oil production output of fracturing effect out of reach, realize adding continuously sand, control and metering and added sand.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the birds-eye view of the utility model part-structure.
Concrete enforcement
As shown in the figure, continuous sanding device adopts and partly pulls, all-hydraulic form, engine drive hydraulic power source 5 on the platform, and hydraulic power source 5 drives horizontal belt machine 6,11 motions of inclination belt feeder through retarder.The sand delivering car rear portion has been equipped with two and has received the arm oil cylinder, is used to shrink belt.Inclination belt feeder 11 parts of stretching out can be 18 °～90 ° rotations.Can be according to the diverse location automatic compensation of blending equipment mulling bucket.After hours, hydraulic actuating cylinder 13 is retracted to the upright position automatically with inclination belt feeder 11.
When sand delivering car is started working, at first import sediment transport speed and sediment transport amount by keyboard by operating personal.When sand is fallen on the belt feeder 6,11, belt claims to pass and has just produced weight signal and speed signal.These two kinds of signals are delivered to secondary instrument, and by signal conditioning, computing draws sand flow and accumulating weight.Export an electric current that is proportional to flow simultaneously, the flow of modulated pressure valve, the rotating speed of change HM Hydraulic Motor finally reaches control sediment transport amount.
In fracturing process, must guarantee the material level certain height of blending equipment mulling bucket, making has enough mulling ratios in the fracturing fluid.In the mulling bucket, level sensor is installed, the material level signal is passed in the control system, and control system becomes relevant signal into current output signal through conversion and comes the control ratio valve, changes the folding degree of gate by oil cylinder, reach the flow of control sand, to guarantee the material level in the mulling bucket.
After hydraulic power source 5 starting, 6 entrys into service of horizontal belt machine, inclination belt feeder 11 is transferred to from the horizontal by about 18 degree by vertical angle.Door control 7 is given out a distance according to designing requirement.After treating that all working all finishes, sand delivering car is filled sand storehouse along sediment transport pipe 10 with frac sand with frac sand.
At this moment whole system entry into service, sand is fallen on the horizontal belt machine 6 from the sand door, and horizontal belt machine 6 is transported to sand on the inclination belt feeder 11.Inclination belt feeder 11 is sent to sand in the mulling bucket of blending equipment.
