| Abstract: | The TH302 Well is a three-dimensional extended-reach horizontal well, and it is very difficult to control its trajectory. Drillstring broken happened when drilling to 3851. 92m, thus, this well was compelled to complete drilling in advance. This paper outlines its well program, details well trajectory controlling techniques and main drilling techniques for hole sections, analyzes reasons for drillstring broken and summarizes the successful experiences for employing steering drilling system. |
