Device, more particularly to a kind of big reserves low-power consumption skid sand conveying device.
Background technology
Current hydraulic fracturing job is domestic and international oil, natural gas, the conventional well stimulation of shale gas equal energy source exploitation, and
The mixed glue solution of quartz sand and thickener is the essential working media of fracturing work, and FRACTURING DESIGN is to quartz sand and thickener
The adding proportion of glue is distinctly claimed.Traditional quartz sand addition (referred to as plus sand) is typically assisted using silo car and fracturing blender truck
Complete.After silo car arrives at pressure break scene, silo forms heeling condition in the presence of the elevating ram of chassis, when worker opens
After putting sand valve, quartz sand is flowed into fracturing blender truck receiving hopper under Gravitative Loads in tank, is entered by fracturing blender truck screw elevator
Mixed in agitator tank with thickener glue, be then pumped into fracturing pump entrance point.This mode sand feeding amount regulation is completely by worker
Hand-guided, detection and effectively control can not be carried out, and sand feeding amount numerical value is the rotating speed conversion with screw elevator in constructing
Obtain, therefore larger error between scaled value and actual value be present.In addition, at present silo car silo reserves 7-15 cubic meters it
Between, in order to meet the continuous sand supplying requirement of pressure break, more silo car alternating sand supplying modes are usually taken, are characterized in that silo car is switched
During upper sand amount few period be present.With the maximization of pressure break scale, the sand feeding amount of domestic individual well individual layer has reached 100
Cubic meter, it is more prominent the problem of the discontinuity and inaccuracy of traditional sand injection manner, easily trigger " sand plug " accident, cause
Fracturing work fails.
So far, domestic and international technical staff is to ensureing that continuous sediment transport is explored.A kind of mode is conveyed using high pressure gas
Quartz sand.Gases at high pressure are produced by air compressor machine, promote quartz sand to be transported to along sealing pressure duct from silo car one big
In capacity sand tank body, then it is put into by spiral or belt feeder in fracturing blender truck receiving hopper.This continuous sediment transport mode convey away from
From it is remote, can be to multiple position sediment transports, but transfer pipeline serious wear, system complex, and without solving sediment transport measurement problem.It is another
Kind mode is to be used cooperatively using belt-conveying car with trailer-type silo.Belt-conveying car is trailer-type silo stop-off, trailer-type
Silo capacity reaches 60 cubic metres, and tank bottom belt feeder can be delivered to quartz sand in tank in fracturing blender truck receiving hopper.This mode is stored up
Sand amount is big, equipment attrition is small, but still suffers from the problem of can not measuring sand feeding amount, and needs two equipment to be used cooperatively, therefore accounts for
Ground area is big, buying and maintenance cost are high.
The content of the invention
The purpose of this utility model is to provide a kind of big reserves low-power consumption skid sand conveying device.
The purpose of this utility model is achieved through the following technical solutions：
Big reserves low-power consumption skid sand conveying device of the present utility model, including skid body support system, the skid body base system
