Oil production process device

Abstract

The invention discloses an oil production process device. The oil production process device comprises a sieve pipe, a righter, a check valve, a mixing cavity, a sucker rod, a stirring cavity, a guide pipe, an oil well pump, a reducer, an oil pipe, a reverse head, a sealing short section, a water pump, a control valve, a liquid tank, a heating cable, a distribution box and an inlet valve; and one end of the sucker rod is connected with the oil well pump, and the other end is connected with a rope suspender. The oil pipe and the guide pipe are mounted in a sleeve; an oil pipe valve and a well mouth injection preventing box are mounted at the upper part of the oil pipe; the oil well pump, the stirring cavity, the mixing cavity, the check valve, the righter, the sieve pipe and a plug are mounted and connected to the lower part of the oil pipe in sequence; the upper part of the guide pipe is connected with the reverse head and the sealing short section in sequence, the lower part is fixed by a fixed clamp mounted on the oil pipe, and the lower part is connected with the mixing cavity through the reducer; one end of a sleeve valve is connected with the sealing short section, and the other end is connected with a water nozzle sleeve provided with a water nozzle, the water pump, a flow meter, a control valve and the liquid tank in sequence; and the distribution box is connected with the liquid tank through the heating cable.

Description

technical field [0001] The invention relates to oil extraction equipment, in particular to an oil extraction technology device. Background technique [0002] Traditional oil recovery technology devices generally have the structure of downhole ordinary pipe strings plus ground conventional facilities. This structure of oil recovery technology devices has played a role in oil recovery, but it also has the following shortcomings or deficiencies: ① Some oil and gas wells When the downhole pressure is insufficient, the backwashing operation cannot be effectively implemented, which makes the wellbore not smooth enough and affects the production efficiency; ② some oil wells have insufficient energy in the oil layer, and when the wellhead is mixed with water to supplement energy, it is easy to suspend the wellbore on the upper part of the well fluid The "dead oil" in the pump is washed into the pump, causing the pump to stick to the pump; ③The production cannot be accurately mixed w...
