Heavy oil steam huff and puff injection-production integrated device

Abstract

The invention discloses a thickened oil steam huff and puff injection-production integrated device comprising a driving device, a gas injection-oil production integrated well, an oil pipe, a sucker rod, a double-metal screw rod pump and a cam anchor, wherein the driving device comprises a base, a box body, a motor and a motor base; an oil well jacket is arranged on the gas injection-oil production integrated well; the oil well jacket is sleeved outside the oil pipe; the stator of the double-metal screw rod pump is connected with the bottom of the oil pipe; the cam anchor is arranged at the lower end of the stator; the sucker rod is arranged inside the oil pipe; the lower end of the sucker rod is connected with the rotor of the double-metal screw rod pump, and the upper end of the sucker rod is connected with a polish rod; the polish rod and the motor are in transmission connection; a sealer is arranged inside the base; the lower end of the base is connected with the gas injection-oil production integrated well; a first thermal insulation cushion is arranged between the base and the gas injection-oil production integrated well; the upper end of the base is connected with the box body; a second thermal insulation cushion is arranged between the base and the chassis body; and the box body is hinged with the motor base. The thickened oil steam huff and puff injection-production integrated device provided by the invention integrates a gas injection device with an oil production device, so that the production aging of a thickened oil well can be improved.

Description

technical field [0001] The invention relates to a heavy oil oil field exploitation device, in particular to an integrated heavy oil steam huff-puff injection-production device. Background technique [0002] Steam stimulation is also called periodic steam injection, steam immersion, and steam stimulation. As the main measure of thermal recovery of heavy oil, it has been widely used in the development of heavy oil; the so-called steam stimulation is to inject a certain amount of high-temperature steam into the oil well with high pressure, shut down the well for a period of time, and wait for the thermal energy of the steam to diffuse to the oil layer. A method of increasing production of heavy oil by restarting well production. The process of steam stimulation operation can be divided into three stages, namely steam injection, brine and recovery. Therefore, this process requires two different sets of devices for steam injection and oil production; during steam injection, it ...
