| Abstract: | The construction of Jimusar Shale Oil horizontal well is facing technical problems such as low rock breaking efficiency of conventional PDC bit,instability of borehole wall,serious auger pressure,large torque and friction,etc.,which seriously affects the construction progress.To this end,special-shaped tooth PDC bit devel?opment,high-performance soil-free water-based drilling fluid technology,efficient high-power screw selection,hydraulic parameter design and other technical studies were conducted to form a horizontal well and fast drilling technology suitable for the well.The field application has significant speed-up effects.The single-pass screw drilling tool in the horizontal section of the well J10026_H has a length of 1756 m,an average machine speed of 11.3m/h,and a drilling period of 35.02 days.The efficient development of Jimusar shale oil provides technical support. |
