The steam pipeline extends into the ground from the ground to heat crude oil in the oil extraction well and nearby outside, the viscosity of the crude oil is reduced, the operation condition of the oil extraction pump is improved, the steam comes from a water body entering the steam generator, after the steam is produced, the steam booster pump is used for boosting and injecting the steam into the underground, the steam is used for providing the same effect of supplementing oil pressure, the oil pressure of crude oil is prevented from being reduced too much and cannot flow into an oil well, the jet pipe is used for mixing the steam and the oil gas separated from the crude oil, the jet pipe forms a negative pressure region at a local part when high-pressure steam airflow from the steam booster pump flows through the jet pipe by utilizing the Bernoulli principle or venturi tube principle, and after the oil gas is connected to the region, the steam can wrap the oil gas and flow out from an outlet of the jet pipe, and then the oil gas is injected into the underground;
because steam is injected into the oil layer for reducing the viscosity, original crude oil pumped by the oil extraction pump is mixed with some fine sand grains, oil gas and also liquid or gaseous water, and the original crude oil is preferably separated once during the extraction, so that the steam can be recycled (the steam injected into the underground but not lifted up is not circulated), the subsequent treatment steps of the crude oil are reduced, the proportion of the oil gas in the crude oil is reduced, and a transport tool only transports the liquid crude oil, thereby improving the transport efficiency. Separation is performed via a separator into: crude oil, oil-water-steam mixed gas and liquid water, fine sand is deposited in the liquid water, the liquid water flows to a steam generator, and the steam generator regularly cleans fine sand grains.
The separator can be separated by centrifugal separation, standing separation and the like, as long as the separation purpose can be achieved, four interfaces are arranged outwards from the separator, and the four interfaces are used for separating three types of output materials: the crude oil is output from a crude oil outlet, oil gas and water vapor are output from a gas outlet, liquid water and fine sand particles are output from a water outlet, the crude oil outlet is externally connected with an oil storage vehicle or an oil delivery pipeline, the water outlet is connected with a steam generator, the gas outlet is connected with an injection pipe, a separator and each pipeline are closed and isolated from the external atmosphere, therefore, the pressure of the crude oil output from an oil extraction pump cannot be lost, the crude oil outlet needs a certain pressure for conveying the crude oil externally, the steam is injected back to the ground and needs the pressure, and the steam booster pump pumps the steam with the certain pressure and directly pressurizes and conveys the steam with only atmospheric pressure, so that a large amount of electric energy can be saved.

There must be some means to ensure that the crude oil only flows out of the crude oil outlet, only gaseous substances are discharged from the gas outlet, only liquid water and fine sand particles are left in the water outlet, and the first and second cut-off assemblies of the present invention play this role.
The first stopping assembly is arranged at the water outlet, the whole density formed by the floating ball, the connecting rod and the valve pad is between water and crude oil, the floating ball approximately represents the gravity center position of the floating ball, the connecting rod and the valve pad, the floating ball can be suspended on an oil-water interface, when the liquid water flow entering the separator is reduced due to more crude oil in the separator, the oil-water interface in the separator is reduced, the floating ball, the connecting rod and the valve pad are then reduced until the valve pad is attached to the water outlet to block the water outlet, and the crude oil cannot be discharged from the water outlet. The second cut-off assembly at the gas outlet operates on the same principle as the first cut-off assembly and also identifies the interface between the gaseous mixture and the crude oil by means of the float, except that the density of the float is different from that of the float on the first cut-off assembly, namely the density between the water vapor and the crude oil.

The second cut-off assembly 216 at the outlet 213 operates on the same principle as the first cut-off assembly 215, and also identifies the interface between the gaseous mixture and the crude oil by means of the float, except that the density of the float is different from that of the float 2151 on the first cut-off assembly 215, and is between that of the water vapor and the crude oil. When the gas-oil interface floats to a certain degree, the gas outlet 213 is blocked, so that the crude oil cannot be discharged from the gas outlet 213.
As shown in fig. 1, the underground assembly 1 further comprises a harmonic vibrator 14, the harmonic vibrator 14 is arranged on the outer surface of the oil production pump 12 or on the inner wall of the oil production well 11, the harmonic vibrator 14 is positioned in the crude oil layer, and the ground assembly 2 further comprises a vibrator power supply 25, wherein the vibrator power supply 25 is electrically connected with the harmonic vibrator 14. The harmonic vibrator 14 can emit vibration waves of a specific frequency to crush surrounding crude oil and further reduce the viscosity, and the vibrator power supply 25 on the ground supplies power to the harmonic vibrator 14 and controls the vibration frequency.
As shown in fig. 1, the steam line 13 includes a steam spray head 131 disposed at an end of the line. The steam nozzle 131 finely atomizes the steam injected into the crude oil layer, which helps to heat the crude oil and reduce the viscosity.
The oil extraction pump 12 is a vertical screw pump. The requirement on the suction condition of the screw pump is reduced, the operation is stable, the reliability is higher than that of other types of oil extraction pumps, and the adaptability to the viscosity of crude oil is better.
The oil extraction pump 12 has a motor at the lower part and an outlet at the upper part. The motor is arranged below the base, so that the motor is fully contacted with flowing crude oil, the heat of the motor is taken away, and the heat dissipation effect is achieved.
The inner wall of the oil production well 11 is provided with a coupling frame, and the oil production pump 12 is installed in a coupling mode. The coupling installation has a large number of applications on the sewage pump in the sewage well, but the oil extraction pump 12 of the invention can play a role of convenient disassembly and assembly by adopting the coupling installation, and the oil extraction pump 12 only needs to sink to a specified depth along the coupling frame without arranging other fixed structures.
The using process of the invention is as follows: high-temperature steam is injected into a crude oil layer through a steam booster pump 23 on the ground to reduce the viscosity degree of crude oil near an oil extraction pump 12, the crude oil flowing into an oil extraction well 11 from the crude oil layer is lifted upwards by the oil extraction pump 12, the mixture contains crude oil, liquid water, oil gas, steam and fine sand grains, pressure maintaining separation is carried out in a separator 21, the liquid water and the fine sand grains flow into a steam generator 22, the water is evaporated again and pressurized by the steam booster pump 23, the gas mixture discharged from a gas outlet 213 is wrapped up and injected into the crude oil layer again to maintain the crude oil layer pressure, and the separated crude oil is conveyed or stored from a crude oil outlet 212 discharge device in the next step.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
