胜利1井钻井液技术难点在于钻井周期过长、泥浆老化严重、长裸眼段井壁稳定、高温井壁稳定及油气保护,通过不同地层使用不同钻井液体系、添加相应处理剂、改变钻井液密度、粘度、润滑等性能满足井下要求,确保井下安全。通过对钻井液性能、钻时记录评价胜利1井钻井液使用效果,为胜利区块后续钻井提供技术借鉴。
Victory 1 well drilling fluid technical difficulties lie in the drilling cycle is too long, serious mud aging, long borehole section of the well wall stability, high temperature borehole wall stability and oil and gas conservation, through different formation using different drilling fluid system, add the appropriate treatment agent to change the drilling fluid density , Viscosity, lubrication and other properties to meet the underground requirements to ensure safety underground. Through the drilling fluid performance, drilling time record evaluation Shengli 1 well drilling fluid use effect, provide technical reference for the follow-up drilling of Shengli block.
