Controlling Technology and Practice of Borehole Azimuth

Zhang Donghai(Drilling Company No. 2, Zhongyuan Petroleum Exploration Bureau )  
The wellhole azimuth is one of the important parameters of borehole quality on whichthe influence factors are very complicated. This paper discusses some parameters (wellhole geometricalparameters, drilling operation parameters,the bottom-hole assembly,etc. ) and formation characteristics.Through discussing optimization of location, well angle and direction are defined, this paper summarizeshow to adjust wellhole direction.
