Abstract
The invention relates to a multi-functional controller for increasing yield of oil. The said controller includes software package of expert system, liquid stream comparator, rotation position sensor, frequency converter or composite intelligent module, and CPU control module. Based on signal of oil output situtation dynamically detcted by the liquic stream comparator, the expert system analyzes and calculates oil output situation of oil pumping unit, so as to find out the static and dynamic operating points of maximum oil output. Thus, the oil pumping unit, stroke ratio etc. are adjusted to their optimal running point, making yield of oil reach maximum.
Description
The present invention relates to a kind of multifunctional oil increasing controller, the intelligence that is mainly used in the oil-field oil pumper motor increases oil control, is that the actual perfection that combines with the high and new technology technology of field produces embodies, and has realized that the oil field had not only increased oily but also energy-conservation oil recovery purpose.
The conventional type oil pumper that now adopt in the oil field generally uses traditional control method, because the particularity of pump load operation, cause several big shortcoming in the use: 1. starting load is too high, impacts greatly, causes ancillary facility type selectings such as distribution transformer capacity and motor excessive.2. because the down-hole build-up of fluid phase constantly changes, need to adjust jig frequency and stroke than improving output, traditional way is to adjust the balance of well pumping unit piece and change drive, need to stop production and adjust for a long time, and the artificial accuracy of adjusting is very poor, and time and effort consuming causes the not only underproduction but also increases expense.
The objective of the invention is to overcome above drawback, and provide a kind of multifunctional oil increasing controller, this product has remedied that the conventional pumping unit speed adjustable range was narrow in the past, mechanical wear is big, the life-span is short, high deficiency consumes energy, the whole process that makes the adjustment of oil production equipment and control and oil extraction operation is a revolution of oil field oil exploitation by manually changing automatic control into.
The objective of the invention is to realize by following two aspects:
First aspect (software), the built-in expert system software bag of this controller, during work, expert system is mainly according to the fuel-displaced situation signal of liquid flowing ratio than the device detection of dynamic, the fuel-displaced situation of analytical calculation oil pumper, that approaches gradually finds the maximum fuel-displaced operating point of sound attitude, and automatically oil pumper is adjusted to the operation of best point, to be implemented under the condition that does not stop production jig frequency number (jig frequency number, be the reciprocating number of times of oil pumper per minute), stroke is than (stroke ratio, be oil pumper when motion, the ratio of upstroke and the running time of down stroke; Stroke, i.e. a stroke moving up or down of sucker rod) adjust to best point (being that maximum goes out oil drop) automatically, oil pumper is realized that self adaptation regulates and control automatically, significantly improved pumping efficiency, make the oil production of oil pumper reach maximum automatically.Simultaneously, system also can realize all functions according to artificial intervention, promptly sets according to artificial parameter, and the expert system software bag regulates jig frequency automatically, adjust stroke compares etc., thereby reaches the maximum oil pump capacity that experience is recovered the oil.
Expert system software when operation, at first carry out system initialization (the determining etc. of setting, balance weight position signalling that comprises various sampling time intervals), then detect whether the oil pumper enabling signal is arranged, if the oil pumper enabling signal is arranged, just start oil pumper; Under the normal condition, oil pumper is pumped with time interval T1 operation by historical data; When system satisfies examination stripping spare, mode is taken out in examination with definite time interval of network analysis, at first count in the scope and continuously change the jig frequency number with time interval T2 in actual jig frequency, the oil pump capacity that compares each jig frequency number, find the jig frequency number of maximum oil pump capacity, and by this state operation, this moment, the stroke ratio was 1: 1; Then under the jig frequency number of maximum oil pump capacity, continuously change stroke with time interval T3 at stroke that reality allows in than scope and compare τ, with the oil pump capacity of each stroke ratio with do not change stroke and compare than the size of preceding maximum oil pump capacity, if fuel-displaced quantitative change is big, just the stroke ratio by maximum oil pump capacity keeps a record and the actual stroke ratio that changes, and by this state operation, if each change stroke than after oil pump capacity and do not change stroke and compare than preceding maximum oil pump capacity size and all not have to become big, just move by the jig frequency number of maximum oil pump capacity and 1: 1 stroke ratio; Under the normal condition, oil pumper is pumped with time interval T1 operation by historical data, when system satisfies examination stripping spare, continuously change the process of jig frequency number and stroke ratio more than the repetition, the variation of the oil pumper operating mode that causes to adapt to liquid level change under the oil well makes the oil pumping amount of oil pumper remain maximum.
Second aspect (hardware), the present invention includes relatively sensor (liquid flowing ratio is than device) of the oil mass that the places ground size that has that it's too late, oil pumper moves to each characteristic point sensor (rotational position sensor), the brake unit and the braking resistor of high-performance transducer (or composite intelligent module) and brake usefulness, subenvironment thermostat and temperature pick up and heating tube, heavy-current control module, low-voltage DC source module, operating mode shows and acousto-optic warning device, master cpu module, from control CPU module etc.Liquid flowing ratio is used to detect the size of oil pumper oil yield and oil pump capacity than device, and its electrical signal links to each other with the input of single-chip microcomputer through amplifier and analog-digital converter, fuel-displaced signal is inputed to single-chip microcomputer carry out the data processing; Rotational position sensor is used for the collection of getting of oil pumper run location information, and its output links to each other with the input of single-chip microcomputer through buffer amplifier array and reverse driven or Schmidt trigger array, and the oil pumper position signalling of gathering is handled by single-chip microcomputer; High-performance transducer (or composite intelligent module), it is input as power frequency power electricity, is output as the continuously adjustable dynamic predictable power supply of frequency and supplies with pumping-unit motor, and the control end of high-performance transducer (or composite intelligent module) is through linking to each other with CPU from the control module; Main control module is the core component of entire controller, its peripheral operating mode demonstration, acousto-optic warning and memory of connecting.This controller also is provided with temperature control module and coupled temperature pick up and heating tube, is used for the control of selection of temperature signal and heating.
The invention has the advantages that: this controller integrates modern high technology technology such as information technology, control technology, computer technology, variable-frequency control technique (or composite intelligent building block technique), sensor technology, is the perfect adaptation of field produces reality and modern high technology technology.Find a kind of practicable pumping production amount that makes for the oil field and reached maximum method, improved the effective rate of utilization of oil production equipment, reduced and waste, saved the energy.
