葡南油田注采系统压力节点分析与对策

Analysis and countermeasure of pressure nodes of injecstion-production system in the southern Putaohua Oilfield

结合葡南油田的油藏特性和开发动态,在研究地层流出动态、环空测试模拟计算方法的基础上,以系统效率为目标函数,运用油水井供排协调理论,确定各个部分的能量损耗,并提出了相应的对策;对地面管网系统能耗进行分析,建立了注采系统地面管网能耗分析的数学模型,分析了能耗的影响因素及应采取的措施。

Combining with the reservoir characteristics and development dynamics of the southern Putaohua Oilfield and basing on the study on the formation outflow performance and annulus logging calculation method,this paper takes system efficiency as the object function and uses the theory of harmonious supply- drainage of oil and water wells to determine the energy consumption of each part, and proposes some corresponding resolvement.It analyzes the energy consumption of the surface pipeline network, constructs a mathematical model for the analysis on this energy consumption of injection- production system, and analyzes the effect factors of the consumption and some resolvement.
