The invention provides a horizontal type shale gas metering system which at least comprises a first gas-liquid separating tank, a second gas-liquid separating tank, a gas-liquid separating buffering tank, a gas-liquid buffering tank, a gas flowmeter and a liquid flowmeter, wherein the first gas-liquid separating tank, the gas-liquid separating buffering tank, the second gas-liquid separating tank and the gas-liquid buffering tank are connected in sequence, and the gas-liquid separating buffering tank is flatly and horizontally arranged, but the first gas-liquid separating tank, the second gas-liquid separating tank and the gas-liquid buffering tank are vertically and uprightly arranged, so that shale gas can pass through the first gas-liquid separating tank, the gas-liquid separating buffering tank, the second gas-liquid separating tank and the gas-liquid buffering tank in sequence, and gas and liquid that are separated can be metered after the shale gas passes through the second gas-liquid separating tank. The horizontal type shale gas metering system realizes precise measurement of the shale gas during on-line and real-time detection and transmission, is high in repetitiveness, and cannot be affected by the flowing state, so that separated water can be metered independently, and the metering accuracy of liquid and water is improved.
Description
technical field [0001] The invention relates to the technical field of natural gas exploitation, and more specifically relates to a horizontal shale gas metering system. Background technique [0002] Shale gas is a natural gas resource that can be exploited in shale formations. China's shale gas recoverable reserves rank first in the world. The formation and enrichment of shale gas has its own unique characteristics, and it is often distributed in thick and widely distributed shale source rock formations in the basin. Compared with conventional natural gas, shale gas development has the advantages of long mining life and long production cycle. Most gas-producing shales are widely distributed, thick, and generally contain gas, which enables shale gas wells to maintain long-term stable growth rates. Gas production rate. [0003] In the project of extracting shale gas, it is necessary to measure the extracted gas to facilitate generation management. The existing metering met...
