[0002] Oilfield oil production mainly adopts mechanical oil production equipment. After more than 100 years of development, two series of rod oil production equipment and rodless oil production equipment have gradually formed. According to statistics, there are about 1 million oil production wells in the world, of which more than 90% Rod oil production equipment is used in oil wells. Rod oil production equipment mainly includes oil pumps, sucker rods, pumping units, tubing string wellhead devices, etc. The main disadvantage is that the ground driving devices such as pumping units are relatively large, and the overall rod oil production system The steel consumption is large, and the energy utilization rate

Embodiment Construction

[0016] refer to figure 1 , including driving wheel 5, continuous oil-absorbing belt 3, weighted bearing 13 and housing 2, driving wheel 5 and squeezing wheel 7 are set in housing 2, squeezing wheel 7 is tangent to driving wheel 5, continuous oil-absorbing belt 3 is tight Set on the driving wheel 5 and the weighted bearing 13 inside the casing 1 placed below the liquid level of the crude oil 12, the casing 2 is sealed and connected with the casing 1, and the continuous oil absorption belt 3 is tightly placed on the driving wheel before the crude oil is extracted and lifted. On the wheel 5 and the weighted bearing 13, the weighted bearing 13 drives the continuous oil-absorbing belt 3 to gently lower into the casing 1 until it is immersed in the crude oil 12. The continuous oil absorption zone 3 in the crude oil 12 fully absorbs the crude oil 12 . Driven by the power, the drive wheel 5 rotates counterclockwise, driving the continuous oil-absorbing belt 3 to rotate counterclockwi...

Abstract

The invention relates to the technical field of oil field production and discloses an oil suction device. The device includes a driving wheel, an oil continuous suction band, a weighed bearing and a casing, wherein the casing is internally provided with the driving wheel and a squeeze wheel, the squeeze wheel is tangent to the driving wheel, the oil continuous suction band is sleeved on the driving wheel and on the weighed bearing arranged in a sleeve below the oil level, the casing is in sealing connection with the sleeve, the oil continuous suction band is driven by the driving wheel to achieve cyclic rotation to drive crude oil in the sleeve to the ground, and the crude oil is squeezed and collected. The device is advantaged in that the crude oil is lifted, the oil suction device is simple and reliable, the occupation land area is small, the device is easy for mounting and maintenance, energy saving is substantially achieved, and oil production cost is substantially reduced.

Description

technical field [0001] The invention relates to the technical field of oil recovery in oil fields, in particular to an oil absorbing device. Background technique [0002] Oilfield oil production mainly adopts mechanical oil production equipment. After more than 100 years of development, two series of rod oil production equipment and rodless oil production equipment have gradually formed. According to statistics, there are about 1 million oil production wells in the world, of which more than 90% Rod oil production equipment is used in oil wells. Rod oil production equipment mainly includes oil pumps, sucker rods, pumping units, tubing string wellhead devices, etc. The main disadvantage is that the ground driving devices such as pumping units are relatively large, and the overall rod oil production system The consumption of steel is large and the energy efficiency is high. Contents of the invention [0003] In order to overcome the defects of the prior art, the present inve...
