The blockage of pipeline deposits in the gas gathering and transportation system equipment will easily lead to increased localized corrosion and overpressure, which will reduce the efficiency of pipeline transportation and affect safe and stable production. To this end, Puguang Branch of Zhongyuan Oil Field Company has developed a new cleaning process centering on “chemical cleaning agent + cleaning processâ€. In the case that gas wells are not shut down, the container sand washing operation is carried out. The photo shows the Puguang 107 gas gathering station took the lead in implementing the sand production operation for the first time and accumulated experience for the next sand washing operation.
