随着陇东油田侏罗系油藏进入中高含水期,措施增产难度增大,陇东油区的措施挖潜方向逐渐由侏罗系延安组转向三叠系延长统。华池油田华152区是开发延长统的试验区块,研究华152区油层堵塞机理与解堵工艺方法,对陇东油田后期的有效开发具有重要的现实意义。 As the Jurassic reservoir of Longdong Oilfield enters middle-high water cut period, it is more difficult to increase production. The direction of tapping the potential of Longdong Oilfield is gradually turned from Yan’an Formation of Jurassic to Yanchang Formation of Triassic. Hua-152 area of ​​Huachi Oilfield is a pilot area for the extension of the extension system. It is of great practical significance to study the blockage mechanism and plugging process of the reservoir in the Huadu 152 area, which is of great significance to the effective development of the late Gansu oilfield.
