Description
Technical field
The utility model relates to petroleum tool, is specifically related to a kind of oil well draining residue deposition device.
Background technology
In oil extraction in oil field process, the liquid of collection is generally impure, can contain trickle sand grains and slag particle, can produce wearing and tearing to the plunger of oil well pump and lining, directly affects the service life of oil well pump, can shorten the pump detection period of oil well pump yet. If often there is holddown phenomenon, just need to, to pumpingh well overhaul, can waste a large amount of man power and materials. On oil field, the general slag prevention device for oil release that adopts separates with slag particle the sand grains gathering in liquid at present, although existing slag prevention device for oil release can play certain sand setting and sediment effect, but owing to only having very little storage slag space on antiresiduum device, can't resolve the problem of the interior a large amount of sand grains of well and slag particle far away.
Summary of the invention
The purpose of this utility model is to provide both effectively sand setting and sediments of one, can solve again the draining residue deposition device of a large amount of sand settings, sediment storage problem.
Technical solution of the present utility model is: it comprises top connection, outer tube, lower contact, slag-proofing cap, upper valve ball, upper valve ball seat, upper short circuit, central tube, lower short circuit, lower valve ball and lower valve ball seat, lower contact is provided with the draining hole that is positioned at lower valve ball seat below, the one end in draining hole is along the radial opening of lower contact in the outer wall of lower contact, the other end is axially upwards connected with the through hole of lower valve ball seat along lower contact, the bottom of lower contact is provided with the storage sand tube for being connected storage sand oil pipe not being connected with draining hole and connects internal thread hole, on lower contact sidewall between the position of lower contact outer wall and the lower short circuit of lower contact installation, be axially arranged with clearance hole, the upper end of clearance hole is opened on the upper surface of lower contact between outer tube and lower short circuit, lower end is connected internal thread hole upper surface with storage sand tube is connected.
Technique effect of the present utility model is: use it both can make effectively deposition and reduce oil well pump is caused to wearing and tearing and stuck of sand grains in the collection liquid in oil extraction in oil field process and slag particle, can solve again a large amount of sand settings, problem that sediment storage area is inadequate. The storage sand tube interface that the bottom of lower contact arranges can be according to how many external any oil pipes that go out the quantity of slag as storage slag bag, the sediment and the reservoir sand that can mass storage be separated, effectively solved that existing slag prevention device for oil release can only separate, the defect of storage area deficiency. And then reach the wearing and tearing that reduce oil pump plunger piston and lining, the service life of improving oil well pump, the object that extends the pump detection period of oil well pump. In the time of workover, the pollution that can also avoid the Residual oil in tubing string to cause ground.
