An Analysis of Scale Formation in Gathering System of Weigang Oilfield and New Scale Cleaning Techniques

Scale formation in the gathering system of Weigang oilfield is serious and severely influences the normal production and economic benefits. The causes and components of scale formed in gathering pipeline, water-mixing system and heater are analyzed. The disadvantages of chemical cleaning methods currently in use are presented including polluting environment, high cost and poor effects. It is proposed to carry out research on high -pressure water jet flow scale -cleaning technique and put it into use as quickly as possible.
