Abstract: Zhao66-ping21 well is the first difficulty wavy horizontal well of Daqing oilfield,it has those problems,such as measurement-while-drilling information delay,geology circumstance complex,predicted reservoir depth inaccuracy,place tool and high precision control difficulty of track in wavy well section,and also it has difficulties of easy sticking of tool for larger friction and torque,difficulty to certain build-up rate of dynamic drilling rig and smaller direction drilling proportion.MPR system while-drilling bellows to multiphase measurement electric resistivity equipment,it has 32 original resistivity curves and 8 compensate curves,promoted measurement accuracy.Established predict method of well figures,angle of bedding,and wellbore data of drilling bit by MPR system,successfully finished this well,and realized drilling 567 m horizontal well with vertical drop 5m,angle of inclination 86°to 92.86° in reservoir of 0.6 m thickness,advanced drilling technology in thin reservoir of Daqing oil field.
