Description
technical field:
The utility model relates to a kind of blanking plug, is specifically related to a kind of sand control blanking plug.
background technology:
At present, in oil extraction in oil field completion industry, need to carry out well workover and play oil pipe, when the sand control treatment of part neighbor distance compared with long oil interval drawn by pin, generally need to use blanking plug the packer at adjacent monolayer gravel filling sand prevention tubing string top and support formula to be produced to sentence and convert sand control bridging plug to every device temporarily.In the similar sand control treatment of tradition packer upper strata carried out to the operations such as pressure testing, perforation, well-flushing when not using blanking plug, the leakage of pin Liu shaft bottom or deficit comparatively people's exceptional well section, may cause and cannot reclaim after Long-Time Service tradition blanking plug, greater risk is brought, a kind of new technical scheme of special proposition to operation.
utility model content:
The purpose of this utility model is the weak point existed to overcome above-mentioned prior art, and provides a kind of sand control blanking plug, and it is easy to use, simple to operate, be easy to large-scale promotion application.
The technical solution adopted in the utility model is: a kind of sand control blanking plug, comprise body, go out sandpipe, valve, valve positioner and well body, well body is the cylinder of hollow, well body inwall contacts with fixed head, fixed head is connected with hydraulic stem one end, the hydraulic stem other end is connected with hydraulic press, hydraulic press is positioned at hydraulic fluid tank inside, hydraulic press is connected by wire with controller, controller is connected by wire with pump machine, described well body inside is provided with body, body inside is provided with hydraulic fluid tank, body bottom is provided with sand room, sand room is connected with sand-feeding tube one end, the sand-feeding tube other end is connected with suction sand table, sand-feeding tube is provided with pump machine, top, sand room with go out sandpipe and be connected, go out sandpipe and be provided with valve, valve is connected by wire with valve positioner, conical head is provided with bottom body.
The beneficial effects of the utility model are: in use, body is put into down-hole, when body arrives assigned address, hydraulic press hydraulic control bar, hydraulic stem controls fixed head, is attached to by fixed head on well body inwall, utilizes the pump housing that sandstone is drawn into sand chamber interior from sand-feeding tube simultaneously, avoid sandstone to the damage of machine, bring a lot of convenience to user.
accompanying drawing illustrates:
Fig. 1 is the utility model structural representation.
detailed description of the invention:
With reference to accompanying drawing, a kind of sand control blanking plug, comprise body 1, go out sandpipe 2, valve 3, valve positioner 4 and well body 5, well body 5 is the cylinder of hollow, well body 5 inwall contacts with fixed head 7, fixed head 7 is connected with hydraulic stem 6 one end, hydraulic stem 6 other end is connected with hydraulic press 15, it is inner that hydraulic press 15 is positioned at hydraulic fluid tank 14, hydraulic press 15 is connected by wire with controller 13, controller 13 is connected by wire with pump machine 12, described well body 5 inside is provided with body 1, body 1 inside is provided with hydraulic fluid tank 14, body 1 bottom is provided with sand room 11, sand room 11 is connected with sand-feeding tube 8 one end, sand-feeding tube 8 other end is connected with suction sand table 9, sand-feeding tube 8 is provided with pump machine 12, top, sand room 11 with go out sandpipe 2 and be connected, go out sandpipe 2 and be provided with valve 3, valve 3 is connected by wire with valve positioner 4, conical head 10 is provided with bottom body 1.In use, body 1 is put into down-hole, when body 1 arrives assigned address, hydraulic press 15 hydraulic control bar 6, hydraulic stem 6 controls fixed head 7, is attached to by fixed head 7 on well body 5 inwall, utilizes the pump housing 12 that sandstone is drawn into sand room 11 from sand-feeding tube 8 inner simultaneously, avoid sandstone to the damage of machine, bring a lot of convenience to user.
