采用计量新技术提升采注适应力

Application of New Metering Technology to Strength Adaptability of Surface Injection and Production System

随着油田的不断开发,全油田综合含水持续上升,要维持一定的原油产量,势必造成油田产液量持续上升。由于油田开发常常存在"重油轻水"的现象,对注水工程调整改造的投资不足,多数油田注水系统设备及管网的腐蚀、老化等问题严重制约了油田的后期生产。通过对油田注水系统存在的主要问题进行分析,提出要维持油田的原油产量,必须维持一定的油田污水处理、污水回注的增长,使之与油田产液量的增长相适应的观点。从精准计量入手,加大注水井调整和作业力度,增加污水回注的注水井点,提高污水回注的应急能力,采用新式计量技术,降低计量误差,真正实现"注好水、注够水",最大限度地挖掘自身潜力,提高地面采注系统的适应能力,为油田可持续发展奠定基础。

With continuous development of Jianghan Oilfield,its comprehensive water content is rising continuously.To maintain the output of crude oil to a certain level will inevitably result in continuous rise of fluid production rate of the oil field.Because much attention has been usually paid to oil and less to water in oil field development and inadequate investment has been put into water injection system adjustment and reconstruction,corrosion and aging of the majority of equipment and pipelines in water injection system has seriously restricted later production of the oil field.Analyzed are main problems in oil field water injection system and it is point out that oil field waste water treatment volume and waste water reinjection volume shall be increased continuously so as to maintain the output of crude oil and make the output of crude oil compatible with continuous rise of fluid production rate of the oil field.
