Abstract: The theory and technology of wellbore trajectory control is the key and fundamental issue in petroleum drilling engineering. With the development of directional, cluster and horizontal wells, the degree of difficulty about wellbore trajectory control increases gradually. One important problem is how to undertake a further theoretical research and how to transfer the existing theoretical achievements to practical means of control in order to increase control accuracy and save drilling cost. This paper reviews the development of trajectory control theory and summarizes state-of-art of technology and existing problems. A new idea and conception about development on this topic are presented.
