Application of Screen Temporary Plugging Technology in the Adjustment Wells in Shuanghe Oilfield

Multiple pressure systems have formed in the targets of Shuanghe and Jianghe oilfields due to the long period of development. Complex situations such as well kick, over flow and sticking of tools occur frequently in drilling operation. Screen temporary plugging technology is applied to modify drilling fluid and completion fluid and positive pressure differential drilling technology is used in drilling operation. Field application shows that the operating process is simple, the success rate is high, drilling cost is low, and the oil and gas layers can be effectively protected.
