摘　　要：运用自行研制的新型动态结垢试验仪对新疆宝浪油田地层结垢问题进行了动态试验研究 ,发现该油田注水过程中结垢受 CO2 分压、注入水 p H值以及注入水和地层水混配比等多种因素的影响。地层结垢量随 CO2 分压的增大而减少 ,随 p H值增大而增大 ,随混配水中地层水比例增加而增大 。A dynamically experimental study on scaling in Baolang oilfield in Xinjiang is carried out with a newly self developed scale testing instrument It is found that the scaling during water injection process in the oilfield is affected by various factors such as CO 2 partial pressure, pH of injected water and the ratio of injected water to formation water The scaling rate of injected water decreases with the increase of CO 2 partial pressure, and increases with the increase of pH,formation water in the mixed water and formation temperature
