Description
Technical field
The present invention relates to the measurement instrument in a kind of petroleum works.
Background technology
The pumping metering is the work that often will do in the petroleum works swabbing operation, and whether the pumping gage work improves the accurate admission that directly has influence on operational data.A kind of metering side jar is arranged in the prior art; Mainly comprise the tank body that is installed in the outlet of well head tapping line; Tank base is provided with discharging tube, and discharging tube is provided with exhaust-valve, and the down-hole is extracted liquid out and directly got in the tank body through pipeline; Convert yield through the height of liquid level in the tank body then, can be through the exhaust-valve of tank base with the tank body emptying.Its weak point is: because the tank body blow-by is extracted liquid out and spilt easy contaminated environment; Do not have deaerating mechanism, cause measuring inaccurate; Because labor cleaning side's jar workload is very big, and cleaning does not thoroughly influence the metering accuracy; Because Extract viscosity is big, condensation point is higher and emptying in time, causes Extract obstruction fluid pipeline or measuring tank to empty and stop work; In the existing technology, also do the pumping metering, be difficult to popularize but cost an arm and a leg with three phase separator.
Summary of the invention
The objective of the invention is for overcoming the above shortcoming of prior art; A kind of automatic emptying pumping measuring tank is provided, makes it can hydrops in tank body and the pipeline be avoided in the automatic emptying of liquid in tank body and the feed liquor pipeline; Simultaneously, also can reduce environment pollution, sand control, anti-solidifying.
For realizing above-mentioned purpose: automatic emptying pumping measuring tank provided by the invention, comprise the feed liquor pipeline that is connected with the well head tapping line, the feed liquor pipeline is connected tank inner chamber, and tank base is provided with discharging tube, and discharging tube is provided with exhaust-valve; Said feed liquor end of line is provided with the feed liquor sleeve pipe; The feed liquor valve is installed on the feed liquor sleeve pipe, and the tank body support cover plate that is fixed with suitable for reading, feed liquor sleeve pipe uprightly are fixed on and support on the cover plate; Be provided with the feed liquor core pipe that matches with the feed liquor sleeve pipe in the feed liquor sleeve pipe; Be provided with the emptying piston that matches with tank body in the tank body, the emptying piston be fixed on the driving mechanism that supports on the cover plate and be connected, feed liquor core pipe lower end is fixedly connected and connects tank inner chamber with the emptying piston; Also be provided with exhaust core pipe on the emptying piston, exhaust core pipe is provided with the spool piece that matches with exhaust core pipe outward, and said spool piece is uprightly fixing on the cover board, and spool piece is provided with outlet valve.
When the present invention works; Driving mechanism can drive the emptying piston and in tank body, slide up and down; Can drive simultaneously feed liquor core pipe and exhaust core pipe and in corresponding feed liquor sleeve pipe and spool piece, slide, when initial, the emptying piston is positioned at the tank body inner top; Feed liquor valve and outlet valve are in opening, and exhaust-valve is in closed condition; Down-hole liquid is gone into tank inner chamber through the feed tube linear flow under swabbing action, the gas in the flow is deviate from, and discharges through outlet valve.Originally take out time end and, open exhaust-valve after liquid meter, the sampling in the tank body, simultaneously with feed liquor valve and exhaust valve closure, through drive mechanism emptying descent of piston, the liquid in the compression tank body, liquid is discharged from discharging tube, accomplishes tank body and empties automatically; Then outlet valve and exhaust-valve are closed, open the feed liquor valve simultaneously, driving mechanism drives the emptying piston stroking upward once more; In tank body, form negative pressure; Liquid in the feed liquor pipeline is all sucked in the tank body, and the descending once more discharge liquid of emptying piston is realized the automatic air emptying function of feed liquor pipeline.So just accomplish one and take out the inferior work that liquid in pipe empties, the feed liquor pipeline liquid empties.The present invention can be with the automatic emptying of liquid in tank body and the feed liquor pipeline; Avoid hydrops in tank body and the pipeline; Simultaneously; Because tank body seals relatively, reduce down-hole liquid to the pollution of environment pollute, can sand control, prevent that the liquid that the well pumping is come out from solidifying in tank body and feed liquor pipeline, and influence is used and measure accurately.The present invention can be applicable in the petroleum works pumping metering operation.
For making thoroughly emptying of liquid in the tank body, said emptying piston soffit and tank body inner bottom part are the spherical that matches.Cooperation through sphere can make on the one hand that liquid compiles to the exhaust-valve import in the tank body, thoroughly the interior liquid of emptying tank body; Spherical structure has good supporting intensity on the other hand, can reduce the piston wall thickness, reduces cost, and can also improve the reliability of device.
For the liquid that makes the pumping from the down-hole can more fully outgas, said feed liquor core pipe lower end is provided with the liquid outlet that parallels with tank body circumference tangential.Flow can produce eddy flow in getting into tank body the time, and gas is deviate from more easily.
For making all emptyings of liquid in the feed liquor pipeline, said feed liquor pipeline comprises the initial pipeline section that is provided with the balance admission valve, and initial pipeline section is connected with the hydrops pipeline section, the upright pipeline section of the terminal connection of hydrops pipeline section, and upright pipeline section end links to each other with the feed liquor sleeve pipe.The effect of balance admission valve is under negative pressure, can connect atmosphere; During the emptying pistons work; Can be through the hydrops pipeline section with liquid emptying in the feed liquor pipeline, when initial pipeline section from the balance admission valve when the hydrops pipeline section is downward-sloping gradually, help liquid emptying in the feed liquor pipeline more; Said hydrops pipeline section can be the hydrops bend pipe, also can be the hydrops case.As on upright pipeline section, flow meter being set, can further facilitate the metering of flow.
Said driving mechanism can be following structure, promptly comprises uprightly being fixed on the oil cylinder that supports on the cover plate, is provided with the plunger that matches with oil cylinder in the oil cylinder, and plunger and emptying piston fix.This structure also can cylinder and air rammer substitute.
