燃气轮机直接拖动注水泵技术方案对比论证

Reasoning of Technical Scheme Using Gas Turbine to Drive Water Injection Pump Directly

油田在开采过程中产生的大量天然气,一般采用放空燃烧处理,既浪费能源,又污染环境,而油田注水系统多数采用电动机拖动注水泵,电量消耗大,用燃气轮机直接拖动注水泵可有效利用放空的天然气,具有节能、环保作用。文章论述了用燃气轮机直接拖动注水泵的必要性和可行性,从技术和经济方面对两种燃气轮机的主要性能参数进行了对比。

Large amounts of natural gas produced in oilfield exploration and production are generally exhausted by burning, which wastes energy source and pollutes environment. But most oilfield water injection systems use electromotors to drive water inject pumps with large amount electric power consumption. Therefore, applying gas turbine to drive water injection pump directly can effectively utilize the exhaust natural gas, which has the functions of energy-saving and environmental protection. This paper discusses the necessity and feasibility of applying gas turbine to drive water injection pump directly and makes technical and economic contrasts on main functions and parameters between two kinds of gas turbines.
