[0002] During the oil extraction process, the mixed fluid of oil and gas in the oil reservoir is transported to the ground through the oil production device. When the pressure decreases, part of the gas in the mixed fluid gradually evaporates from the crude oil to form associated gas, and gradually expands. If the associated gas is not recovered or discharged in time, the dynamic liquid level of the oil well will drop, affecting the pump efficiency and making the oil pump unable to work normally. Therefore, a mobile oil and associated gas recovery and utilization device is needed.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 and Figure 4 The utility model provides an embodiment: a mobile oil and associated gas recovery and utilization device, including a base 1, a universal wheel 2 is arranged on the lower surface of the base 1, a push rod 3 is fixedly connected to the upper surface of the base 1, a processing tank 4 is fixedly connected to the upper surface of the base 1, an oil outlet pipe 8 is fixedly connected to the outer wall of the processing tank 4, a first gate valve 9 is fixedly connected to the upper surface of the oil outlet pipe 8, an exhaust pipe 5 is fixedly connected to one side of the outer wall of the processing tank 4, a feed pipe 6 is fixedly connected to the other side of the outer wall of the processing tank 4, a filter assembly 7 is arranged on the lower surface of the feed pipe 6, and the filter assembly 7 includes a valve body 27 and a filter screen 25, the outer wall of the valve body 27 is fixedly connected to the lower surface of the feed pipe 6, the outer wall of the filter screen 25 is arranged on the inner wall of the feed pipe 6, the outer wall of the filter screen 25 is fixedly connected to the inner wall of the valve body 27, and a plug 26 is fixedly connected to the bottom of the valve body 27.

[0025] Specifically, by pushing the push rod 3 to make the universal wheel 2 roll on the ground and moving the entire device to the working position, the feeding pipeline with the oil-gas mixed fluid can be connected to the feed pipe 6, so that the oil-gas fluid flows into the feed pipe 6, and the solid matter in the fluid is blocked by the filter screen 25, so that the liquid phase and gas in the fluid flow to the feed port 23 and enter the treatment tank 4; the filter screen 25 is a high-strength pressure-resistant structure, which can block larger solids in the fluid, and smaller solids flow into the valve body 27, and the solids remaining in the valve body 27 can be cleaned by pulling out the plug 26; the separated oil can flow out of the oil outlet pipe 8 by unscrewing the first gate valve 9, and it can be stored by adding a special collection box.

[0026] Reference Figure 3 A drying plate 19 is fixedly connected to the inner wall of the processing tank 4, a first umbrella plate separator 20 and a second umbrella plate separator 21 are fixedly connected to the inner wall of the processing tank 4 in sequence, a baffle 22 is fixedly connected to the inner wall of the processing tank 4, a feed inlet 23 is opened inside the processing tank 4, and an air outlet 24 is opened inside the processing tank 4.

[0027] Specifically, when the liquid phase and gas in the fluid enter the processing tank 4, they are blocked by the baffle 22, causing the fluid to flow downward. Since the liquid phase in the fluid has weight and settles downward, the gas moves upward through the first umbrella plate separator 20, separating the oil droplets entrained in the gas from it, and causing the oil droplets to adhere to the first umbrella plate separator 20 and flow downward. The rising gas passes through the drying plate 19 to absorb the mixed water therein, thereby achieving gas drying, and then is discharged from the exhaust pipe 5 through the air outlet 24 for recovery; at the same time, the sinking liquid phase passes through the second umbrella plate separator 21, which breaks up and disperses the liquid phase, so that the gas dissolved in the liquid phase can overflow, thereby improving the purity of the liquid phase recovery, and flows to the bottom of the processing tank 4 for accumulation.

[0028] Reference Figure 1 and Figure 2 The outer wall of the processing tank 4 is fixedly connected with a first oil inlet pipe 10 and a second oil inlet pipe 11 in sequence, the upper surface of the first oil inlet pipe 10 is fixedly connected with a third gate valve 13, the upper surface of the second oil inlet pipe 11 is fixedly connected with a second gate valve 12, the outer wall of the first oil inlet pipe 10 is fixedly connected with an oil injection pipe 14, the outer wall of the oil injection pipe 14 is fixedly connected to one end of the second oil inlet pipe 11, the bottom of the oil injection pipe 14 is fixedly connected to the upper surface of the base 1, the outer wall of the oil injection pipe 14 is provided with a visual window 15, the outer wall of the oil injection pipe 14 is fixedly connected with a scale plate 16, the upper surface of the oil injection pipe 14 is fixedly connected with an air outlet pipe 18, and the outer wall of the air outlet pipe 18 is fixedly connected with a pressure relief valve 17.

[0029] Specifically, by unscrewing the third gate valve 13 and the second gate valve 12 on the first oil inlet pipe 10 and the second oil inlet pipe 11, the liquid phase is allowed to flow into the oil filling pipe 14, and the liquid level rise can be checked by observing the visual window 15. When the liquid column rises to the critical position of the scale plate 16, the first gate valve 9 is unscrewed to allow the liquid phase to flow out of the oil outlet pipe 8 for recovery, thereby improving the practicality of the device; by unscrewing the pressure relief valve 17, the residual gas in the oil filling pipe 14 is discharged from the gas outlet pipe 18, and the oil filling pipe 14 is depressurized to prevent the accumulation of residual gas in the oil filling pipe 14, which affects the liquid level change and thus affects the observation effect, thereby improving the safety of the device.

[0030] Working principle: When it is necessary to recover oil and associated gas, first connect the feed pipeline with oil-gas mixed fluid to the feed pipe 6, so that the oil-gas fluid flows into the feed pipe 6, and the solid matter in the fluid is blocked by the filter screen 25, so that the liquid phase and gas in the fluid flow to the feed port 23, enter the processing tank 4, and are blocked by the baffle 22, so that the fluid flows downward. Since the liquid phase in the fluid has weight and settles downward, the gas moves upward through the first umbrella plate separator 20, and the oil droplets entrained in the gas are separated from it, and the oil droplets are attached to the first umbrella plate separator 20 and flow downward. The rising gas passes through the drying plate 19 to absorb the mixed water, so as to achieve gas The oil is dried and then discharged from the exhaust pipe 5 through the air outlet 24 for recovery; at the same time, the sinking liquid phase flows to the bottom of the processing tank 4 through the second umbrella plate separator 21, and then the third gate valve 13 and the second gate valve 12 on the first oil inlet pipe 10 and the second oil inlet pipe 11 are respectively unscrewed to make the liquid phase flow into the oil injection pipe 14. The liquid level rise can be checked by observing the visual window 15. When the liquid column rises to the critical position of the scale plate 16, the first gate valve 9 is unscrewed to make the liquid phase flow out from the oil outlet pipe 8 for recovery; at the same time, the pressure relief valve 17 is unscrewed to make the residual gas in the oil injection pipe 14 be discharged from the air outlet pipe 18, and the oil injection pipe 14 is depressurized, thereby realizing the recovery of oil and associated gas.
