Description
Technical field
The invention belongs to the desanding technical field of gathering system extraction liquid in the oilfield exploitation, relate in particular to a kind of pipe type sand remover that in than removal extraction liquid under the low differential pressure, contains sand.
Background technique
In the oil extraction process, because all factors such as geological condition often contain a large amount of silt particles in the extraction liquid.The content of these silt particles is between 0.01～1.0%, and these long-pending sand often are deposited in dehydration plant, settling tank and pipeline even the oven, the wearing and tearing of the stoppage in transit of Zhao's forming apparatus, pump and valve.
The sand removing process using that adopts mainly contains three kinds at present, and a kind of is big jar of sand setting technology, makes liquid to do long stop in oil tank, makes the sand natural subsidence in jar, and this subsidence style is the most ancient, and the sand that avales needs regularly artificial the removing; Second kind is sand removing process using vortex flow, utilizes gathering system pressure, makes liquid to pass through hydrocyclone, utilize the different of liquid and sand density difference, produce different centrifugal force, sand slips into the long-pending sand hopper of hydrocyclone bottom along wall, and liquid flows out from the hydrocyclone flow-off.The advantage that hydrocyclone is removed sand is the efficient height, and equipment is little, and shortcoming is that required pressure reduction is bigger, and fitness for purpose is at 0.2-0.5MPa, and system often can not provide high like this pressure.The third is a pressure type pipe sedimentation sand remover, utilize the multipole combined packing in the current piping, reduce liquid reynolds' number sand setting, sand setting enters interior discharge of sand removing device of duct bottom, but because the poor mobile performance of sand setting, be easy to stop up sand removing device, sand setting can't be discharged, influence desanding effect.
A kind of pressure piping formula sand remover that the Chinese patent ZL 00243719.8 of on February 13rd, 2002 bulletin discloses, constitute by segregation section, sand collecting hopper, liquid level control method, material level control switch, sand flash valve, safety valve, base for supporting, it is characterized in that main body is made up of in two of its underpart sled seats that become conical vessel or a plurality of conical vessel and bottom one section tubular container, a screw type drag reduction head is installed in the segregation section inducer, multistage wing plate filler is installed in horizontal tubular container.Though this sand remover has the higher sand coarse aggregate ratio of removing, operation does not have the pressure reduction influence yet, and the sediment outflow weak effect has in the husky bucket of collection under the situation of a large amount of long-pending sand and can stop up sand flash valve, normally sediment outflow.
The model utility content
The purpose of this utility model provides a kind of simple in structure, and desanding and sediment outflow are effective, can remove sand grains and the pressure difference Δ P≤0.02MPa of particle diameter d 〉=50 μ m.
The technical solution adopted in the utility model is as follows:
A kind of pressure piping sand remover with a plurality of sediment outflow buckets, the tank body container that comprises the horizontal positioned that can be connected in the pipeline, the two ends of tank body container are respectively equipped with liquid inlet and liquid outlet, the bottom of tank body container is provided with the sediment outflow bucket, it is characterized in that being equipped with in the sediment outflow bucket sediment outflow pipe and swirl flowing device, the sediment outflow pipe is L shaped bend pipe, the one end is a sand jet outlet, the other end is a sand inlet, sand inlet is the funnel shaped of wide-mouth, sand inlet of desanding pipe extends vertically up to the bottom of sediment outflow bucket, and sand jet outlet is positioned at the outside of the husky bucket of row; Swirl flowing device is made up of flushing intake pipe and cyclone separator, cyclone separator is sleeved on the upper end of sand inlet of desanding pipe, the cyclone separator outlet is near sand inlet of desanding pipe, the flushing intake pipe is communicated with the cyclone separator upper end along the tangent direction of cyclone separator, its the other end stretches out the sediment outflow headwall, and the internal diameter of cyclone separator outlet is greater than the external diameter of sediment outflow pipe.
Described sediment outflow bucket is the cylindrical shape that taper or bottom are sphere.
The number of described sediment outflow bucket is two or more.
Described cyclone separator outlet is positioned at the neck of sediment outflow pipe funnel shape sand inlet.
Place in the described tank body container man type with angle or upsiloid multi-layer plate-type combined packing are housed.
The top of described tank body container is provided with relief valve port.
This pressure piping sand remover can directly insert in the oilfield transportation system, oil field mining liquid is flowed into by the liquid inlet of the tank body container of horizontal positioned, under the effect of gravity sedimentation takes place after the sand body process filler rectification in the extraction liquid, sand body sinks to interior deposition of a plurality of sediment outflow buckets of tank body container bottom setting.Flushing water intake injection pressure sparge water in the sediment outflow bucket by swirl flowing device, sparge water enters along the tangent direction of cyclone separator, and be the rotation attitude by cyclone separator outlet and flow out, make the long-pending sand flowization at sand jet outlet place, thereby long-pending sand and current mixture are sucked from funnel shaped sand inlet of desanding pipe, and the sediment outflow pipe sand jet outlet outside the sediment outflow bucket is discharged.The sediment outflow bucket can be cylindrical shape or taper, and its shape is to the not influence of sediment outflow effect.
The beneficial effect of this model utility is that this pressure piping sand remover with a plurality of sediment outflow buckets is simple in structure, can effectively prevent from and eliminate to be deposited on the obstruction that the long-pending sand in the sediment outflow bucket causes, and makes long-pending sand have mobile performance, discharges smoothly.
