摘要：
At present, coalbed methane (CBM) development in the Qinshui Basin has been transformed into multi-well cluster deployment mode from the earlier single-well deployment mode. In order to optimize the CBM gathering and transportation system in the Qinshui Basin further and deal with the "three highs" problem (high energy consumption, high investment and high idling rate of equipment) existing in the current CBM gathering and transportation system, with the demands of two stages (i.e., system development and operation) taken into consideration comprehensively, this paper established the corresponding economic benefit calculation model and optimization model. Then, combined with the economic and technological analysis and software numerical simulation, a new design concept of "pipeline network with interconnected trunk lines" was put forward. That is to build and lay connecting pipelines between different blocks to make the equipment spare to each other, so that the idling rate of equipment can be reduced effectively. And the following research results were obtained. First, the adoption of the design concept of pipeline network with interconnected trunk lines can realize the interconnection of gas production systems and increase the flexibility of the pipeline network, so as to effectively increase the average station load rate, equipment utilization rate and operation efficiency, reduce energy consumption, and improve economic benefit. Second, the application effect of this concept to the productivity construction of 4×108 m3/a in a certain block of the Qinshui Basin shows that the investment in the system is reduced by 20%, the average station load rate increased by 30%, the operation efficiency increased by 10%, the operation energy consumption reduced by 20%, and the benefit increased by over CNY 20 million. In conclusion, this design concept is of an important guiding significance to the development and construction of new blocks in CBM fields in the future. © 2019, Natural Gas Industry Journal Agency.
