北东块三元复合驱见效后,油井结垢将逐渐严重,在调研其它试验区块时,洗井过程中洗井参数对结垢的影响均未详细研究,没有可借鉴的成果。本文分析了结垢的外部影响因素,对洗井周期、洗井排量、洗井温度等洗井参数对洗井的影响方式和影响程度进行了分析论证,确定了洗井参数优化的方法。 After the North East Block ASP flooding has taken effect, the scale formation of the oil wells will gradually worsen. During the investigation of other test blocks, the effect of the well flushing parameters on scaling during the well flushing process has not been studied in detail and there is no available result for reference. This paper analyzes the external influencing factors of fouling, and analyzes and verifies the influencing modes and influence degree of well flushing parameters on well flushing, such as flushing cycle, well flushing displacement and well washing temperature, and determines the method of well flushing parameter optimization.
