【摘要】：随着油田进入高含水开发阶段,联合站的运行能耗不断增加,运行效率不断降低。而联合站是一个由单体设备组成的有机整体,各个单体设备之间相互联系,相互制约,单个设备的运行最优并不能保证系统处在运行最优状态。所以分析和了解联合站整体和部分的用能情况,以在系统的角度对联合站运行参数进行优化分析是十分必要的。本文以纯梁首站为研究对象,在联合站工艺流程一定的条件下,对联合站进行了能耗分析和运行参数优化研究。首先对联合站的主要设备建立了能量平衡模型,进行了能量平衡分析,在主要设备能量分析的基础上建立了联合站整体能量平衡分析模型,对联合站整体进行了用能分析。然后在联合站运行参数仿真的基础上,计算了运行费用,并以运行费用最低为目标函数,分析和确定影响联合站运行费用的参数,确定运行参数的约束条件,建立优化数学模型,选择启发式算法遗传算法对优化模型进行了求解。经过优化,联合站的运行费用由优化前的2273.2万每年降到了2050.3万每年,单耗由优化前的16.35kgce/t降到了15.32kgce/t,表明不对工艺流程进行改造,通过对运行参数进行优化也能达到节能降耗的目的。最后使用C++builder编程工具编制了课题能耗分析和运行优化辅助计算软件。
[Abstract]:As the oilfield enters the stage of high water cut development, the operation energy consumption of the combined station is increasing and the operation efficiency is decreasing. The combined station is an organic whole composed of single equipment. Each unit equipment is interrelated and restricted each other. The optimal operation of single equipment can not guarantee the system to be in the optimal state of operation. So it is necessary to analyze and understand the whole and part of the energy use of the combined station and to optimize the operation parameters of the joint station from the system point of view. In this paper, the energy consumption analysis and operation parameter optimization of the combined station are studied under the certain technological process of the combined station, taking the first station of pure beam as the research object. Firstly, the energy balance model of the main equipment of the combined station is established and the energy balance analysis is carried out. On the basis of the energy analysis of the main equipment, the overall energy balance analysis model of the combined station is established, and the overall energy use analysis of the combined station is carried out. Then, on the basis of the simulation of the operation parameters of the combined station, the operating cost is calculated, and taking the lowest operation cost as the objective function, the parameters affecting the operation cost of the joint station are analyzed and determined, and the constraint conditions of the operation parameters are determined. The optimization model is established and the heuristic genetic algorithm is chosen to solve the optimization model. After optimization, the operating cost of the combined station was reduced from 22.732 million before optimization to 20.503 million per year, and the unit consumption was reduced from the 16.35kgce/t before optimization to 15.32 kgces / t, indicating that the technological process was not modified. The purpose of saving energy and reducing consumption can also be achieved by optimizing operation parameters. Finally, the software of energy consumption analysis and operation optimization is developed with C builder programming tool.
