Quality Improvement and Practice of Hot Washing in Oil Wells
In one oil field,conventional hot washing is the main method and high pressure hot washing is the auxiliary method.In or-der to achieve high efficiency and energy saving hot washing effect and reduce the number of wax stuck wells,the hot washing cycle has been optimized in recent years through the innovative application of the"chart method"to achieve accurate hot washing of me-chanical wells.The exploration and implementation of"large displacement hot washing method"and"accelerated hot washing meth-od"can effectively improve the effect of wax removal and the level of hot washing.In order to improve the efficiency of hot washing in small pump wells,hot washing auxiliary tools such as double acting hot washing valve and hot washing guide are studied and applied.Through application and practice,the effect of hot washing is further improved.
