Embodiment Construction

[0014] Below in conjunction with embodiment the present invention is described in further detail: referring to accompanying drawing, the method for extracting oil with linear motor is to use linear motor as the power drive equipment of oil well pump or double as oil well pump with linear motor to extract crude oil, that is to say, use linear motor That is, it is used as power-driven equipment and as an oil well pump. When the linear motor is used as the power drive equipment of the oil well pump, the linear motor is lowered into the well through the oil pipe and connected with the rod oil well pump. The connection method between the linear motor and the rod oil pump is to connect the motor mover 2 of the linear motor with the plunger of the rod oil pump through the connecting piece. The linear motor can be installed above the rod oil pump or installed on the rod pump. Below the oil pump. The linear motor oil well pump used in the above method includes the floating valve 3, th...

Abstract

The present invention discloses a method for oil production by using linear electric motor and its linear electric motor oil well pump. Said method is characterized by that the linear electric motor can be used as power drive equipment of oil well pump or the linear electric motor can be used as oil well pump for pumping crude oil. The linear electric motor oil well pump includes the following several portions: traveling valve of oil well pump, plunger and fixed valve, the traveling valve and plunger are mounted in the interior of linear electric motor, and the fixed valve is mounted in the oil pipe interior under the linear electric motor.

Description

technical field [0001] The invention relates to an oil production process and equipment in the petroleum industry, in particular to a method for oil production using a linear motor and a linear motor oil pump, which is applicable to various oil production wells. Background technique [0002] The electric energy consumption of oil field extraction is very huge, accounting for more than 30% of the production cost. Among them, the energy consumption of the rod pumping system accounts for a relatively large proportion. Taking the beam pumping unit system as an example, the maximum target value of the entire system efficiency is only 38.4%. Technology" "Petroleum Machinery" 2001 5th period. If the traditional oil pumping system device does not change, it is very difficult to increase the system efficiency by 1%. Simplifying the ground and underground driving equipment is the most effective way to improve the efficiency of the rod pumping system. In addition, the traditional oil...
