苏里格气田单井产量低、建井数量多,因此确定最优集气半径是集输系统优化的关键问题。通过计算苏里格气田某区块不同建产规模和集气半径的采气管道长度,采用建井密度和等效面积等方法计算类比其他区块不同集气半径的采气管道长度及投资,结合相应集气半径的集气站及集气支线投资,最终确定其最优集气半径。
Sulige gas field has a low production per well and a large number of wells. Therefore, determining the optimal gas collection radius is a key issue in the optimization of the gathering and transportation system. By calculating the length of gas production pipelines with different production scale and gas collection radius of a block in the Sulige Gasfield, the gas pipeline length and investment analogous to the gas collection radius of other blocks are calculated by using well density and equivalent area, Combined with the corresponding gas collection radius gas gathering stations and gas gathering branch investment, and ultimately determine the optimal collection radius.
