摘　　要：埕岛油田位于渤海湾浅海海域内,其馆陶组油藏系粉砂质细砂岩油藏。针对其油层特征,选用了以PAC141、K—PAM、SK—Ⅱ、MHP、JFF为主处理剂的海水钻井液体系。经现场试验证明,该海水钻井液具有较强的抑制性、较好的润滑性和造壁性,解决了聚合物钻井液配浆性与抑制性的矛盾;该钻井液体系固相含量低,滤失量低,pH值低,对油层损害小。满足了埕岛油田馆陶组油层钻井工程和油层保护的需要。Chengdao oil field is located in the neritic area of Bohai bay , with a sandstone reservoir of aleuritic texture . A completion fluid composition is presented to protect oil reservoir . This system has the advantage of good shale inhibition , lubricity , lower solids , and lower filtrate . It is shown that this fluid can satisfy the demand of oil reservoir protection .
