| 页岩气集输系统组合增压是目前最适用的增压方式.为了优化页岩气集输管网的增压位置,基于现有页岩
气田增压模式,建立了混合整数非线性规划模型(MINLP),模型以压缩机总成本最小为目标函数,约束条件包括管
道压力和流量约束、压缩机约束、节流约束、压力平衡约束、气井增压和平台增压唯一性约束以及气井流量约束.
以某页岩气区块为例,利用通用代数模型系统(GAMS)对优化模型进行求解,得到对应的组合增压方案.结论认为:
①该优化模型可以根据页岩气区块实际生产情况,通过编程求解,在现有增压方式中优选出合适的组合增压方案;
②气井增压和平台增压同时考虑时,优化得出的增压位置更集中、压缩机数量更少,体现了组合增压方式在页岩气
集输系统增压中的优势;③各种组合增压方式下压缩机总运行功率大致相同,且站点处运行功率总是大于其他增
压位置;④当压缩机进出口压差和处理量越大时,配置的压缩机额定功率也越大、购安成本越高、机组总成本也越

| 英文摘要 |
| Combination pressurization of shale gas gathering systems is currently the most popular pressurization
method. To optimize the pressurization position of shale gas gathering pipeline network, a mixed integer nonlinear pro
gramming model (MINLP) is developed based on the existing shale gas field pressurization model with the minimum total
cost of compressor as the objective function and constraints including pipeline pressure and flow constraints, compressor
constraints, throttling constraints, pressure balance constraints, gas well pressurization and platform pressurization unique
ness constraints, and gas well flow constraint. Taking a shale gas block as an example, the general algebraic modeling
system (GAMS) is used to solve the optimization model to obtain the corresponding combined pressurization scheme. And
the following conclusions were reached. Firstly, the optimization model can be programmed to solve for a preferred com
bination of pressurization schemes among existing pressurization methods based on the actual production of the shale gas
blocks. Secondly, when gas well pressurization and platform pressurization are considered simultaneously, the optimized
pressurization location is more concentrated and the number of compressors is smaller, reflecting the advantages of the
combination pressurization method in the shale gas gathering systems pressurization. Thirdly, different combinations of
pressurization methods have approximately the same total compressor operating power, and the operating power at the site
is always greater than other pressurization positions. Fourth, when the compressor inlet and outlet pressure difference is
bigger and the processing capacity is larger, the rated power of the configured compressor also increases, the purchase cost
is higher and the total cost of the unit is also higher. |
