Abstract
The invention relates to a method for remotely automatically adjusting oil well random-load balance. The method includes the steps that an automatic adjusting control center, a torque detection unit, a power detection unit, a pumping unit stroke detection unit, a controllable balance weight positioning unit, a site manual unit, a controllable balance weight unit and an RTU remote control unit form an automatic system; the automatic adjusting control center receives input signals of the torque detection unit, the power detection unit, the pumping stroke detection unit, the controllable balance weight positioning unit and the site manual unit, conducts high-speed computing and then drives the controllable balance weight unit to move, the optimal position of a controllable balance weight is achieved when the upper stroke torque and the lower stroke torque of a pumping motor are most stable, and the automatic adjusting control center controls the controllable balance weight unit to achieve the optimal position; the automatic adjusting control center is in two-way communication with the RTU remote control unit. By the implementation of the method, oil well random-load balance can be remotely automatically adjusted under the condition that an original operating mode of a pumping unit is unchanged, and the goals of reducing loads and energy consumption of the pumping unit are achieved when the loads of a well mouth change.
Description
Technical field
The present invention relates to a kind of remote auto and regulate oil well with carrying balance method, be applicable to the pumping well of all models, belong to oil drilling and extracting equipment field.
Background technique
Along with deepening continuously of oil field energy saving work, there are in recent years many New Power Saving Pumping Units, as: the energy-saving beam pumping units such as two horse heads, fork, down eccentric barbell formula
Two Horse Beam Pumping Units are strengthened counterbalance effect by changing the Changing Pattern of net torque factor, reach energy-conservation object.It is to take conventional machine as basic model, its fourbar linkage has been carried out to critical technological change, adopted between walking beam postbrachium, walking beam and the crossbeam of particular curve type and adopted flexible connecting structure, the special fourbar linkage changing with the variation of crank angle to obtain rocking bar (walking beam postbrachium) length, length of connecting rod, i.e. " variable element fourbar linkage ", has formed a kind of pumping unit main structure that can adapt to the new type power transmission of oil recovery actual conditions.During the work of this machine, rely on the regular variation of its walking beam postbrachium effective length realize load when large trimming moment large, the working state that load hour trimming moment is little, thus strengthen the counterbalance effect of pumping unit, realize energy-conservation intention;
Swing link beam-pumping unit is to adopt crank--the new structure pumping unit that fork drives slotted link mechanism to do reciprocating linear motion, and fork is adjusted moment voluntarily for the variation of suspension point up-down stroke magnitude of load, reaches the effect energy-conservation compared with beam-pumping unit;
Down eccentric barbell series energy-saving pumping unit is on the basis of beam pumping unit, utilizes down eccentric barbell to carry out balance and cuts down pumping unit Peak torque, can be according to position and the weight of hole condition Proper Match down eccentric barbell;
Although these pumping units have all been obtained certain energy-saving effect, all do not have remote auto to regulate oil well with carrying an equilibrium function, make oil well very not steady with carrying balance, reduce the working life of pumping unit equipment and caused the waste of a large amount of electric energy.
Summary of the invention
The object of the present invention is to provide a kind of remote auto to regulate oil well with carrying balance method, utilize it in the situation that the original method of operation of pumping unit is constant, to regulate oil well with carrying balance by remote auto.
