潜油螺杆泵采油系统数值优化方法研究

大系统优化方法是指大规模的线性和非线性规划理论和算法，大系统优化是从系统的全局出发进行建模，在满足所要求的条件下，对各子系统进行协调，最终达到工程系统的全局优化。潜油螺杆泵采油系统与其他人工举升技术相比具有一系列不可比拟的优点。该技术适用于稠油井、高含砂井、高烃链油井的石油开采；潜油螺杆泵是一种新型的无杆采油设备。所以杆管偏磨所导致的断杆和管漏故障可以避免，抽油杆形变产生的能耗可以消除。本文简述大系统的概念、特征、大系统优化的特征以及大系统优化在螺杆泵采油系统中的应用。

Numeric optimization study on ESPCP

Optimization of large-scale system is that large-scale linear and nonlinear programming theory and algorithms. Optimizing the system is proceeding from the overall system for modeling. To meet the required conditions, the various subsystems should be coordinated to achieve the overall system optimization ultimately. The oil exploitation technology of the electrical submersible motor driven progressing cavity pump has much more advantages than other artificial lift methods. The technology especially adapts t...
