Abstract
The utility model relates to a liquid collection drainage disc arranged on the top of a blowout preventer. A cylindrical inner protection guardrail is fixed on an inner ring of the disc bottom, a cylindrical outer protection guardrail is fixed on an outer ring of the disc bottom, four positioning screw rod holes are in uniform and symmetrical distribution on the disc bottom, the concrete positions of the positioning screw rod holes are determined according to the positions of a lifting ring screw rod of the blowout preventer, and a drainage pipe is vertically fixed on the bottom surface of the disc bottom. The liquid collection drainage disc has the effect that the liquid collection drainage disc is fixed above the plane of the blowout preventer, in a process of removing a liquid-containing oil pipe, liquid flows in a ring space of an oil sleeve or in an oil pipe are collected and gathered, pipelines are matched for discharging the liquid flows in a fixed position in time, the pollution and the potential safety hazard caused by uncontrolled free flowing of the liquid flows are eliminated, the construction speed is accelerated, and the operation environment of personnel is improved.
Description
Technical field
The utility model relates to the oilfield downhole operation rig tool, and particularly a kind of special-purpose aid that removes when being with the liquid oil pipe is the liquid collecting drainage dish at a kind of preventer top.
Background technology
At present, when the underground work scene removed oil pipe, often there were liquid stream in the oil jacket annular space of well head or oil pipe inside.By existing control method is earlier at well head periphery corral, digs overflow ditch and ground little liquid storage hole again, and the liquid that well head is flowed out is pooled to the liquid storage hole, and the back is extracted into filth storage can with electric pump, and final tank car reclaims.This method is simple and crude, weak effect, it is difficult to excavate winter, sleety weather pollutes transfer, and exist soak that the workover rig derrick basis causes that derrick tilts, the muddy place personnel that cause slidingly fall, winter gone into the hidden danger that water freezing lost efficacy from observation port by preventer.
The utility model content
The purpose of this utility model is: the liquid collecting drainage dish that a kind of preventer top is provided, when liquid stream is arranged in running into oil jacket annular space or oil pipe, more than the preventer body plane, receive and compile liquid stream, and cooperate pipeline, eliminate liquid stream and do not have pollution and the potential safety hazard that control causes in time with the discharging of liquid stream fixed point.
The technical solution adopted in the utility model is: the liquid collecting drainage dish at preventer top, mainly by try to get to the heart of a matter, interior guardrail, outer guardrail and drainage tube form, it is characterized in that: trying to get to the heart of a matter is the annular surface plate; The interior ring of trying to get to the heart of a matter is fixed with guardrail in the cylindrical shape, and interior guardrail internal diameter is slightly less than the external diameter of preventer flange, is enclosed within after strutting by the elasticity of material that the preventer flange is outer, height is a little less than the height of preventer flange; The outer shroud of trying to get to the heart of a matter is fixed with the outer guardrail of cylindrical shape, and outer guardrail external diameter slightly surpasses the position of preventer observation port inboard, the height of guardrail in highly being same as; Four positioning screw holes distribute on trying to get to the heart of a matter symmetrically, and the particular location in positioning screw hole is determined according to the position of preventer drop handle screw rod; Drainage tube is vertically fixed on the bottom surface of trying to get to the heart of a matter, on operator's opposite.
For eliminating the liquid stream leakage that positioning screw hole and drop handle screw clearance cause greatly, sealing mat is arranged respectively on the top in four the positioning screw holes of trying to get to the heart of a matter.The drop handle screw rod of preventer can compress sealing mat.
The use of the liquid collecting drainage dish at summary preventer top helps to understand the utility model.Liquid collecting drainage dish needs to be used with preventer drop handle screw rod, preventer backplate, liquid-collecting barrel, drainage hose.Unload four drop handle screw rods on the preventer housing earlier, liquid collecting drainage dish is enclosed within on the preventer flange circumference, drainage tube is on operator's opposite, and the positioning screw hole overlaps with drop handle screw rod box hole on the preventer body, and the drop handle screw rod of cover sealing mat is screwed into box and tightens.Cover the backplate on plane on the preventer flange again, it acts on the basis of protection steel ring slot, the double downward fluid course of flange screw of having stopped.Remove in the oil pipe process, oil jacket annular space or the oily intraluminal fluid preventer backplate of flowing through flows into the body of liquid collecting drainage dish, stopped by interior guardrail, outer guardrail after, can only flow into liquid-collecting barrel along drainage tube, realize the fixed point discharging through drainage hose again.
The beneficial effects of the utility model: the liquid collecting drainage dish at the utility model preventer top, be fixed on more than the preventer body plane, reception compiles oil jacket annular space or oily intraluminal fluid stream, and cooperate pipeline in time with the discharging of liquid stream fixed point, eliminate liquid stream and do not have random pollution and the potential safety hazard that causes of dropping down of control, improve speed of application, improved employee's operating environment.
Description of drawings
Fig. 1 is the liquid collecting drainage dish structural profile schematic diagram at the utility model preventer top.
Among the figure, 1-tries to get to the heart of a matter, guardrail in the 2-, the outer guardrail of 3-, 4-drainage tube, 5-positioning screw hole, 6-sealing mat.
The specific embodiment
Embodiment 1: the liquid collecting drainage dish at the SFZ18-21 type preventer top that produces with a suitable North China Oilfield Rong Sheng company is an example, and the utility model is described in further detail.
Consult Fig. 1.The liquid collecting drainage dish at the utility model preventer top selects for use polyurethane injection molded in mould.Mainly by try to get to the heart of a matter 1, interior guardrail 2, outer guardrail 3 and drainage tube 4 form.Try to get to the heart of a matter 1 for the annular surface plate.400 millimeters of internal diameters, 840 millimeters of external diameters, 20 millimeters of 1 wall thickness of trying to get to the heart of a matter.
1 the interior ring of trying to get to the heart of a matter is fixed with guardrail 2 in the cylindrical shape, the tapering of interior guardrail 21: 6,120 millimeters of height, 20 millimeters of wall thickness.1 the outer shroud of trying to get to the heart of a matter is fixed with the outer guardrail 3 of a cylindrical shape, the tapering of outer guardrail 31: 7.5,150 millimeters of height, 20 millimeters of wall thickness.
Four 10 millimeters positioning screw holes 5 distribute on 1 symmetrically trying to get to the heart of a matter, and the particular location in positioning screw hole 5 is determined according to the position of preventer drop handle screw rod; On the top in 1 four the positioning screw holes 5 of trying to get to the heart of a matter a sealing mat 6 is arranged respectively.Drainage tube 4 is vertically fixed on 1 bottom surface of trying to get to the heart of a matter, 100 millimeters of drainage tube 4 external diameters, 60 millimeters of internal diameters, high 150 millimeters, and perpendicular to 1 bottom surface of trying to get to the heart of a matter, 60 millimeters of outer guardrail 3 inner circumferential of center to center distance.
