Development of process simulation software for gathering and transportation pipeline network of intelligent oilfield

针对集输管网多相输送体系、不同拓扑结构及输送工艺在数字油田智能化建设中的仿真模拟需求,基于图论方法和管网对象设计了可表示复杂连接关系的通用管网数据结构,耦合流动单元水热力数学模型与节点平衡关系建立了普适性的管网非线性方程组,提出了鲁棒性高的求解方法。以油田集输工艺设计、运行及优化等场景中独立使用或在综合管理系统中集成应用为目标研制了计算软件,通过对比商业软件计算结果,验证了所开发软件的适应性和准确性,同时从工程实用方面探讨了其应用前景。

In terms of the requirements for simulating multi-phase transportation system,different topological structures and transportation technology of gathering and transportation pipeline networks in the intelligent construction of digital oilfields,a general data structure of pipeline network,capable of expressing the complex connection relationship,was designed on the base of the graph theory method and the target of pipeline network.A universal non-linear equation set of pipeline network was established by coupling the hydro-thermal mathematical model of a flow unit and the equilibrium relationship of nodes,and a solution method with high robustness was proposed.Computing software was developed for the independent use in the scenarios of design,operation and optimization of the gathering and transportation technologies of an oilfield or the integrated application in an integrated management system.By comparing the calculation results of commercial softwares,the adaptability and accuracy of the software were verified,and meanwhile,its application prospects were discussed from the aspect of engineering practice.
