Abstract

The utility model discloses a sand pumping device for a field oil well, which solves the insufficiency in the original technique. The sand pumping device is formed by connecting a dynamic oil pipe, an upper valvegroup, a circulation hole, a single flow valve, a transform buckle, a hexagonal piston rod, an inner hexagon nut, a hard piston, a sealing ring, a pump body, a transform buckle under the pump, a sand sediment pipe, and the sand shovel of a single flow valve; the advantage of adopting the sand pumping device is that: the pump body is connected with the piston rod by adopting the hexagon, and the sand pumping device not only can pump the sand but also can rotate; when the sand pumping has no footage, certain press can be applied and hydraulic pliers are used as the rotating dynamic force, the sand pumping device drills and then pumps, which is repeatedly operated, the sand pumping work can be completed. Compared with the original art, the sand pumping device saves the labor power, material resource, the financial resource, and cleans the environment.

Description

Rotary sand pump

One, technical field: the utility model relates to a kind of oilfield and takes out the sand device, especially rotary sand pump.

Two, background technique: take out in the sand work at oilfield, hard sand cake is formed at layer of sand top after the pressure break, and general sand pump can't carry out pulling out after the fragmentation to the sand cake.Have only and go up the brill dish again, with the powerful flushing of cementing truck, so both wastes of manpower, material resources, financial resources have been polluted oil reservoir again, also large-area pollution are caused on ground while boring.

Three, summary of the invention: the purpose of this utility model provides rotary sand pump, it has solved the deficiency in the original technology, the purpose of this utility model is to realize like this, it by power oil pipe, go up valve group, circulation port, one-way valve, change button, six side's piston rods, interior six square nuts, hard piston, seal ring, the pump housing, pump become down buckle, sand sediment pipe, one-way valve sand shovel be formed by connecting, power oil pipe is installed on the valve group; On the last valve group circulation port is arranged, one-way valve is installed in the valve group, and six side's piston rods are connected with last valve group by becoming button; Interior six square nuts are installed in the upper end of the pump housing; Hard piston upper end is connected with six side's piston-rod lower ends; Seal ring is positioned at hard piston groove; Hard piston is enclosed in the pump housing; Sand sediment pipe links the bottom that is connected on the pump housing by becoming under the pump; One-way valve sand shovel is connected the bottom of sand sediment pipe.

During work, rotary sand pump is lowered to by power oil pipe carries out work in the sleeve pipe, by well repairing machine up and down handling be power, when suction is motionless, drive piston rod with the hydraulic tongs rotation, drive drill bit sand shovel successively the sand cake is carried out fragmentation, realize the purpose of work smoothly.

Adopt the advantage of this device to be: adopt six sides to be connected between the pump housing and piston rod, can take out sand and can rotate again, can add certain pressure and do rotating power with hydraulic tongs when taking out sand and do not have drilling depth, subdrilling is taken out again, and repeatable operation can be finished and take out the sand operation; Compare with original technology, both saved human and material resources and financial resources, cleaned environment again.

Four, description of drawings: Fig. 1 is the structural representation of rotary sand pump, among the figure 1, power oil pipe 2, go up valve group 3, circulation port 4, one-way valve 5, become button 6, six side's piston rods 7, interior six square nuts 8, hard piston 9, seal ring 10, the pump housing 11, pump become down buckle 12, sand sediment pipe 13, one-way valve sand shovel

Five, embodiment: in Fig. 1, power oil pipe 1 is installed on the valve group 2; On the last valve group 2 circulation port 3 is arranged, one-way valve 4 is installed in the valve group 2, and six side's piston rods 6 are connected with last valve group 2 by becoming button 5; Interior six square nuts 7 are installed in the upper end of the pump housing 10; Hard piston 8 upper ends are connected with six side's piston rods, 6 lower ends; Seal ring 9 is positioned at hard piston 8 grooves; Hard piston 8 is enclosed in the pump housing 10; Sand sediment pipe 12 becomes the bottom that button 11 is connected the pump housing 10 down by pump; One-way valve sand shovel 13 is connected the bottom of sand sediment pipe 12.
