The invention relates to hydraulic driving oil extraction equipment, which comprises a sleeve pipe 5, a reversing valve 2, power liquid passages 3 and 4, a liquid generating oil pipe 6, a small oil pipe 7, a cylinder body 12, a power liquid pipe 10, a liquid generating pipe 11, an upper flange 8, a lower flange 13 and an oil pump tube 15, wherein the liquid generating oil pipe 6 is sheathed in the sleeve pipe 5, the small oil pipe 7 is sheathed in the liquid generating oil pipe 6 and extends out from the bottom of the liquid generating pipe 6, a piston is arranged inside the cylinder body 12,the power liquid pipe 10 and the liquid generating pipe 11 are in the arrangement parallel to the cylinder body 12, the piston 9 makes the up-down reciprocating movement along the axial line of the cylinder body 12 under the action of the power liquid, the upper flange 8 is positioned above the cylinder body 12 and connects the cylinder body 12 and the liquid generating oil pipe 6, the lower flange 13 is positioned under the cylinder body 12 and fixes the cylinder body 12 and an oil pipe 14, the bottom of the oil pump tube 15 is provided with a fixed valve 18, and the oil pump tube 15 is connected under the oil pipe 14. The hydraulic driving oil extraction equipment provided by the invention realizes the thick oil horizontal well oil extraction production through reasonable hydraulic transmission. The pump submerging depth is increased, the stroke loss is reduced, and at the same time, the pump efficiency is improved.
Description
technical field [0001] The invention relates to oil production equipment, more particularly, to a hydraulically driven oil production equipment suitable for heavy oil horizontal wells. Background technique [0002] For heavy oil horizontal wells, conventional rod oil production equipment has some shortcomings in production: the oil pump can only go down to a certain depth of the oil well, and requires high bottomhole flow pressure to carry out normal production, resulting in low pump efficiency and low oil well production ; The movement resistance of heavy oil to the sucker rod is relatively large, so that the surface suspension point and the downhole plunger cannot move synchronously, and the stroke loss is greater than that of conventional oil wells. For heavy oil horizontal wells, most oilfields currently use rod production equipment for production. Due to drilling errors in the early development of the oilfield and formation creep in the later production process, some oi...
