Abstract: A mechanical wireless inclinometer to measure hole's deviation was designed.The systematic composition,main technical parameters and key techniques of the inclinometer are described.The structure,principle and interrelation of devices including the deviation-measurement device,control device and mud pulse generator are introduced.The calculation methods in design of devices are given on the basis of kinematics analysis.In addition,the techniques related to lubrication and seal ability of apparatus,such as the function,design performance,features,choice of lubricating oil and sealing element,are discussed.Field application shows that this inclinometer has good adaptability and high anti-temperature capacity and can satisfy the requirement of measuring deviation while drilling in vertical well.It is also suitable for measuring deviation in deep well and high-temperature well.

Key words: mechanical inclinometer, vertical well, measurement while drilling, design scheme, key techniques
