Abstract
The utility model provides a control device for automatic oil gauging of an oil well tipping bucket. The device is characterized in that a three-way valve is connected onto an oil outlet pipeline of the lower part of an original tipping bucket separator, one path of the three-way valve is connected with a pressure gage, the other path of the three-way valve is connected with a differential pressure transmitter, the differential pressure transmitter is connected with a control module, the control module is connected with a time relay, the time relay is connected with a frequency converter, the frequency converter controls a motor to drive a pump, and the pump is connected with an oil tank. The control device has the advantages that the stable, efficient and accurate oil gauging process is realized, and the problem that the separator cannot normally gauge oil as the tipping bucket is submerged is thoroughly solved.
Description
Technical field
The utility model relates to a kind of device of tipping bucket gauging of oil well use, particularly relevant for affect the automaton of the tipping bucket gauging of gauging because of tipping bucket oil spilling.
Background technology
At oil well production field, low accompanying gas or without associated gas oil well, in tipping bucket gauging process, tipping bucket is often flooded, causes normally gauging of eliminator, make this data disappearance of the important parameter in oil well management aspect " well yield ", for oil well management brings difficulty.
Summary of the invention
For solving the problem of aforementioned existence, the utility model provides the control device of the automatic gauging of a kind of oil well dump; This device is on the fuel-displaced pipeline in original tipping bucket eliminator bottom, connecting tee valve, three way cock one road Bonding pressure table, another road connects differential pressure transmitter, differential pressure transmitter is connected with control module, and control module is connected with frequency converter with the time relay, and the time relay is connected with frequency converter, Frequency Converter Control driven by motor pump, pump is connected with oil tank.
The timing time of the described time relay, oil to the required time of certain liquid level of extracting in oil filling according to pump is set, when control module is controlled frequency converter work, when pump extracts the interior oil of oil filling, the time device that continues starts timing, until the oil liquid level in filling with is while reaching desired location value, the contact KA of the time relay disconnects, and pump stops oil pumping.
The utility model has the advantages that, realize steadily, efficiently, gauging process accurately, thoroughly solve and flooded the normally problem of gauging of the eliminator that causes because of tipping bucket.
Accompanying drawing explanation
Accompanying drawing 1 is differential pressure transmitter of the present utility model installation site schematic diagram;
Accompanying drawing 3 is variable-frequency motor and time relay circuit figure;
Number in the figure explanation:
1-oil tank; 2-glass tube oil gauge; 3-three way cock; 4-pressure meter; 5-differential pressure transmitter; 6-connecting pipe; 7-stop valve; 8-one way valve; 9-single-screw (single screw) pump; 10-enters eliminator; 11-trunk line.
The specific embodiment
This device is on the fuel-displaced pipeline in original tipping bucket eliminator bottom, connecting tee valve 3, three way cock 3 one road Bonding pressure tables 4, another road connects differential pressure transmitter 5, differential pressure transmitter 5 is connected with control module, and control module is connected with frequency converter with the time relay, and the time relay is also connected with frequency converter, Frequency Converter Control driven by motor pump 9, pump 9 is connected with oil tank 1.
The timing time of the described time relay, oil to the required time of certain liquid level of extracting in oil filling 1 according to pump is set, when control module is controlled frequency converter work, when pump extracts oil filling 1 interior oil, the time device that continues starts timing, until the oil liquid level in filling with reaches while setting value, the contact KA of the time relay disconnects, and pump stops oil pumping.
The measured result of differential pressure transmitter is pressure differential, i.e. △ P=ρ g △ h.And because oil tank is cylindrical, the area S of its cross section circle is constant, so, weight G=△ PS=ρ g △ hS, S is constant, and h and △ P are proportional.As long as detect exactly differential pressure △ P value, just can draw actual liquid level.The larger liquid level of differential pressure is just higher; Coordinate intelligent secondary meter to calculate the actual differential pressure of oil tank, and establish up/down limit and report to the police, for the signal of starting and stopping pump, when differential pressure reaches setting value, priming pump extracts the oil in oil tank, reduces oil tank level.
In the fuel-displaced pipeline upper shed in original tipping bucket eliminator tipping bucket bottom, install three way cock additional, one tunnel is for setting pressure table, one tunnel is for differential pressure transmitter high-tension measurement point (oil, gas hybrid hydrostatic), at middle part, utilize original glass tube oil gauge to get hydraulic fluid port and install three way cock additional, get differential pressure transmitter low pressure measurement point (air pressure), when differential pressure is too high, automatically start single-screw (single screw) pump, single-screw (single screw) pump is by Frequency Converter Control, can adjust according to actual needs pump speed; In order to prevent oil tank, find time, cause the screw pump idle running damage pump housing, operation bypass increases the time relay for timing operation, be on duty to push back and fall normal value or time relay timing finishes, oil transfer pump quits work, pipeline returns to from stream mode: control model is divided automatically and manual two kinds, utilizes differential pressure value to open, stop oil pump under automatic mode; Under manual mode, hand push button opens, stops.
