Problems solved by technology

[0004] Therefore, in the same gas field cooperation area, there are generally two or more investors conducting development. Since the geological conditions are basically the same, the process plans and technical routes of the natural gas processing and exporting systems constructed by each are basically the same, resulting in processing, exporting and other facilities. Repeated construction, or small construction scale, high investment, long construction period, and many management points are not conducive to maximizing the benefits of investors and affecting the economics of the project

Abstract

The invention relates to a natural gas distribution system, in particular to a natural gas and gas condensate metering and distribution method. The natural gas and gas condensate metering and distribution method is characterized in that: the output end of a block gas collection unit communicates with the input end of a block preseparator, the output end of the block preseparator respectively communicates with the input end of a block raw natural gas metering and component analysis unit and the input end of a gas condensate stabilization unit, the output end of the block raw natural gas metering and component analysis unit communicates with the input end of a natural gas purification unit, the output end of the natural gas purification unit communicates with the input end of a marketable natural gas metering and component analysis unit, the output end of the marketable natural gas metering and component analysis unit communicates with a marketable natural gas conveying pipeline, and the output end of the gas condensate stabilization unit communicates with the input end of a stabilized gas condensate metering unit. The natural gas and gas condensate metering and distribution method effectively solves the problem on how to meter and distribute marketable natural gas and gas condensate as byproduct, expands the scale, reduces the cost, and increases the benefit.

Description

technical field [0001] The invention relates to a natural gas distribution device, in particular to a method for metering and distribution of natural gas and condensate. Background technique [0002] With the development of society and economy, the demand for natural gas as a clean energy is increasing, and the development of natural gas has also entered a period of rapid development. With the injection of domestic and international funds, there are more and more domestic and international cooperation development projects for natural gas. [0003] The mode of natural gas cooperative development is generally to divide several areas with development value in the same gas field, and invest and develop them by different investors. Each investor independently builds various facilities required for natural gas extraction, processing and transportation, so that the extracted natural gas can be sold to downstream users under the condition that the national commercial gas index is me...
