| Abstract: | Based on the difficulties in long open-hole of deep wells in Magu block of Liaohe oilfield, a drilling fluid technology is developed and applied successfully. In that block, the polymer organosilicon drilling fluid system and asphalt fluid loss agents are used to cooperate solid-liquid lubrication and hole cleaning technologies to prevent caving sticking and hard tripping. |
