Abstract

The invention provides an oil and gas transmission device in a high gas-oil ratio area. The oil and gas transmission device comprises an oil collecting gathering pipe, a skid-mounted supercharging integrated device, an air cooler, an associated gas separator and a gas flowmeter. The outlet of the oil collecting and gathering pipe is connected with the inlet of the skid-mounted supercharging integrated device, the outlet of the skid-mounted supercharging integrated device is connected with the inlet of the air cooler, and the outlet of the air cooler is connected with the inlet of the associated gas separator. The associated gas separator is provided with two gas outlets, one gas outlet is connected with the inlet of the skid-mounted supercharging integrated device, and the other gas outletis connected with the gas flowmeter. The oil and gas transmission device and method in the high gas-oil ratio area achieve oil and gas totally-enclosed collecting and transmission in the high gas-oilratio area. The practical problems of pipeline plug flow in the high gas-oil ratio area, flameout of a heating furnace, damage of an oil transmission pump and the like are solved through oil and gasbuffering, secondary separation and oil and gas divided transmission, the oil and gas transmission efficiency is improved by 80%, and in-situ practical problems are solved. According to the oil and gas transmission device, by achieving the skid-mounted effect of partial equipment, the adaptability of a station yard is improved, the construction period is shortened, and the construction investmentis reduced.

Description

technical field [0001] The invention relates to the technical field of oil and gas gathering and transportation in low-permeability oil and gas fields, and is mainly applicable to a high gas-oil ratio block oil and gas transportation device and method. process method. Background technique [0002] With the large-scale development of oil and gas fields, the output of oil wells is accompanied by a large amount of oilfield associated gas. Due to the geological conditions of the reservoir and the constraints of the topography, the crude oil with high gas-oil ratio is prone to slug flow during the transportation process and is easy to run for a long time. The oil pump is damaged, and the amount of dissolved gas in crude oil is large. The separated associated gas is usually used as fuel for the heating furnace in the station. The high liquid content of the separated associated gas will easily cause the heating furnace to shut down, thereby affecting the transmission efficiency and...
