Embodiment 1

[0024] Taking the hot steam heat source as an example, the crude oil incoming liquid enters the integrated equipment of the present invention from the left end of the crude oil incoming liquid inlet 4, and first undergoes the coalescence and separation treatment of the coalescing sloping plate bundle 8, and the inclination angle of the sloping plate bundle is formed along the axial direction of the pipeline. Set at 40 degrees, the material of the plate bundle is made of stainless steel material with good elasticity and good absorption of oil droplets, the plate bundles are set in parallel, and the plate spacing is set at 10mm according to the characteristics of the incoming crude oil. First, the hot steam enters the heat source inlet 2 in the middle of each inclined plate through the heat source inlet header 3. The hot steam flows inside the inclined plate and exchanges heat with the crude oil and liquid between the inclined plates. Finally, the steam-water mixture after heat ex...

Embodiment 2

[0026] Taking the heat source of heat conduction oil as an example, the crude oil incoming liquid enters the integrated equipment of the present invention from the crude oil incoming liquid inlet 4, and first undergoes coalescence and separation treatment of the coalescing sloping plate bundle 8, and the inclination angle of the sloping plate bundle is 50° The plate bundle is made of stainless steel material with good elasticity and good absorption of oil droplets. The plate bundles are arranged in parallel, and the plate spacing is set at 10mm according to the characteristics of the incoming crude oil. First, the heat transfer oil enters the heat source inlet 2 in the middle of each swash plate through the heat source inlet header 3, the heat transfer oil flows inside the slant plate and exchanges heat with the crude oil and liquid between the slant plates, and finally the heat transfer oil exits the heat source after heat exchange 7 and the heat source outlet header 9 are dis...

Embodiment 3

[0028] Taking the hot water heat source as an example, the crude oil incoming liquid enters the integrated equipment of the present invention from the left end of the crude oil incoming liquid inlet 4, and first undergoes coalescence and separation treatment of the coalescing inclined plate bundle 8. Set at 45 degrees, the material of the plate bundle is made of stainless steel material with good elasticity and good absorption of oil droplets, the plate bundles are arranged in parallel, and the plate spacing is set at 10mm according to the characteristics of the incoming crude oil. First, the hot water enters the heat source inlet 2 in the middle of each swash plate through the heat source inlet header 3, and the hot water flows inside the slant plate and exchanges heat with the crude oil and liquid between the slant plates, and finally the gas-water mixture after the heat exchange flows from The heat source outlet 7 and the heat source outlet header 9 are discharged.

Abstract

The invention relates to petroleum pipeline scale-prevention and demulsification heating equipment and an oil gas-water separation method. A plurality of layers of coalescence inclined plate bundles are arranged in a shell of the equipment; a heat source inlet header and a heat source outlet header are arranged at the two ends of the coalescence inclined plate bundles correspondingly; a heat source inlet is formed in the heat source inlet header; a heat source outlet is formed in the heat source outlet header; the coalescence inclined plate bundles are fixed and tightly connected with the shell through one end of each vibration transmission rod; the other end of each vibration transmission rod is connected with an ultrasonic transducer; a gas collecting pipe communicates with the shell through a plurality of gas collecting branch pipes; and one end of the shell is provided with a crude oil incoming liquid opening, and the other end of the shell is provided with a crude oil incoming liquid outlet. The continuous heating and oil gas-water separation effects of an oilfield produced liquid can be kept efficiently for a long time, the petroleum pipeline scale-prevention and demulsification heating equipment is high in heating effect and descaling capability, the service life is long, the oil gas-water separation efficiency is high, and engineering cost is reduced.

Description

technical field [0001] The invention relates to the technical field of petroleum exploitation, in particular to an oil pipeline anti-scaling and demulsification heating equipment and a method for separating oil, gas and water. Background technique [0002] Oilfield heating furnace is an important equipment in the oil-water separation system for crude oil production. Scaling often occurs during operation. In mild cases, heat exchange pipes are blocked to increase pressure and power consumption. In severe cases, the heating furnace is directly scrapped. At present, heat exchange tubes with larger diameters are used in the design of oil field heating furnaces to prolong the time of scale blockage, which increases the volume of the heating furnace, which not only wastes steel, but also increases transportation and installation costs, even if there is no scaling. However, due to the large diameter of the heat exchange tube and the long distance between the intermediate fluid and ...
