Description
One, technical field
The present invention relates to a kind of sand washing control device of petroleum industry underground work scouring equipment technical field, be specifically related to the anti-overflow blowout hookup of a kind of sand washing.
Two, background technology
The most of well of petroleum industry Downhole Construction all relates to the sand washing operation, Downhole Construction is more and more higher to the requirement of environmental protection and well control now, especially to overflow requirement in the well, taked many kinds of measures, but in the sand washing construction, Adopts measure is few now, and former Adopts measure is the dress ball-and-seat, after the formal dress ball-and-seat, can only recoil during sand washing, unsnatch singlely after the termination of pumping, can't stop overflow in the well, the anti-ball-and-seat that fills, can only square impact, can't recoil, can't change at any time the sand washing mode according to the situation of well, no matter fill the ball-and-seat sand washing, all can't change when dismantling with water tap single, single overflow at well head, the well head overflow has caused the pollution of sewage sump oil, the cleaning difficulty, the cleaning construction that is unfavorable for advocating in the oil field, the profit of well head causes wellhead ground wet and slippery simultaneously, affects well head operating personnel's safety, has stayed larger potential safety hazard.Now comparatively commonly used is to connect ball-and-seat at the single lower of connected with water faucet, but can't stop equally the overflow problem of the interior liquid of well.
When the high pressure oil reservoir is washed in sand washing open, blowout occurs suddenly, if positive sand washing can be closed sleeve gate or be controlled open flow with gate, but the sand washing hose links to each other with cementing truck, can't pound turn on the tap single, the control blowout, pressure is low can also arrive by force single, if pressure is high, just there is very large danger.During recoil sand, export as hose links to each other, now construction generally is that outlet is fixed on hose on the large tank, the uncontrollable outlet discharge capacity of blowout occurs suddenly, even gate is loaded onto in outlet, when blowout occurs, also there is larger potential safety hazard in water tap and go out between the port strobe to be flexible pipe.Load onto cock under the water tap now, can only cut-out tap, the water tap that can't in time fall down is closed well head, and generally to be difficult to the band water tap single for present sand washing mode thus, can not control preferably blowout.
Three, summary of the invention
Purpose of the present invention is exactly the defective that exists for prior art, provide a kind of and can finish smoothly the sand washing operation, while is controlling water kick preferably, play the effect of blowout prevention, make the sand washing operation reach the requirement that environmental protection is produced, better control the generation of blowout well, ensure the anti-overflow blowout hookup of sand washing of construction operation safety.
