Abstract

For increasing unloading speed to reach the objective of continuously flowing back and decrease damage to formation, a new method for unloading to require production is developed which is unloading tech with hydraulic pump. This method has the features of big flowing back intensity, high efficiency, easy operation, deep swabbing depth (over 3500 m) and big unloading per day. By field applications in 5 wells, some fruit has been gained and a new way of unloading in deep well in Changqing oilfield is provided.
