Problems solved by technology
[0003] Most of the low-yield cluster well groups in existing oilfields use wellhead single-draw tanks, which have no metering function and no control. Tank trucks are transported to the processing station, gas and liquid cannot be collected and transported
The production method of low-yield cluster wells not only wastes associated natural gas resources, but also pollutes the atmospheric environment and poses serious fire hazards

The invention belongs to the technical field of separators, and in particular relates to a multi-well gas-collecting liquid-collecting metering separator and a gas-liquid separation method. A multi-well gas-collecting liquid-collecting metering separator, comprising a separator tank body, a sewage discharge outlet and a liquid main outlet are arranged at the bottom of the separator tank, a sewage discharge solenoid valve is provided at the sewage discharge outlet, and a liquid discharge electromagnetic valve is provided at the liquid main outlet. Valve, the separator tank body is divided into several metering bins by a number of metering bin baffles, and the bottom of the metering bin baffles is provided with a metering bin communication hole so that the liquid phase between each metering bin is connected. The separator tank where the metering bin is located is provided with a gas-liquid inlet pipe assembly, a pressure gauge assembly, a temperature sensor assembly, a safety valve assembly and a natural gas outlet. The gas-liquid inlet pipe assembly of each metering bin is connected to a single well output Gas-liquid pipe. The separator can realize the measurement of associated natural gas gathering and transportation, and the liquid can be collected and transported as well as hauled, and the natural gas can be fully recycled to ensure the safety, environmental protection and sustainable development of the oil field.
Description
technical field [0001] The invention belongs to the technical field of separators, in particular to a multi-well gas-collecting liquid-collecting metering separator. Background technique [0002] Oil well production measurement refers to the determination of the oil and gas produced by a single well, which is the key data for oil well management and mastering oil layer dynamics. Outbound metering is the measurement of oil and natural gas delivery flow, and it is the basic basis for oil and gas handover management between exporters and receivers. [0003] Most of the low-yield cluster well groups in existing oilfields use wellhead single-draw tanks, which have no metering function and no control. Tank trucks are transported to the processing station, and gas and liquid cannot be collected and transported. The production mode of low-yield cluster wells not only wastes associated natural gas resources, but also pollutes the atmospheric environment and poses serious fire hazar...
