摘要
GK1H开发水平井属塔河南2号三叠系孔隙型砂岩油藏构造。该井完钻井深为4639m,水平段长260.93m。结合地质地层条件,该井采用聚磺混油防塌钻井液,通过对水平井钻井液的携岩洗井、井壁稳定、减阻防卡、保护油气层等关键技术进行强化,使润滑性、造壁性和抑制性达到协调统一,加强严封堵强抑制,使用适当的钻井液密度以及合理的高效保护油气层技术措施,使钻井施工中钻井液性能优良,取得了良好的施工效果。
The reservoir of the well GK1H(horizontal well)is located in Triassic formations and was a porous sand reservoir.This well was drilled to a measured depth of 4,693 m,with the length of the horizontal section being 260.93 m.Using polymer sulfonate mud mixed with oil,combined with good hole cleaning,wellbore stabilization,friction reducing and reservoir protection designs,the well was successfully completed and satisfactory results were obtained.
