沙特HWY区块HWY-116井提速技术
PETROLEUM DRILLING TECHNIQUES（2020）
Abstract
为提高沙特HWY区块三开直井段钻进坚硬、强研磨性地层时的机械钻速,在HWY-116井三开井段进行了液动射流冲击器旋冲钻井技术试验.根据液动射流冲击器性能参数与岩石抗钻特性参数的关系,与HWY-116井钻井设计结合,优化了钻具组合,选择了与液动射流冲击器配合的PDC钻头,优化了旋冲钻井参数,形成了适用于HWY-116井的?228.6 mm液动射流冲击器旋冲钻井提速技术.应用该提速技术后,HWY-116井三开井段机械钻速为9.40 m/h,与邻井相同井段相比提高了45.5％.这表明,应用液动射流冲击器旋冲钻井技术可以提高沙特HWY区块坚硬、强研磨性地层的机械钻速.
