Abstract
There are 10 wells located in the Shun 9 well field in Silurian system of Shuntuoguole block, 7 of them were drilled wells. The statistics of complex drilling accidents indicated that tight pull, sticking of drill tools, pump blocked and mud loss were major types of drilling accidents in building section of horizontal wells. Specially. The high drill resistance of the formation caused low penetration rate and frequently bits replacing. As a consequence, the exploration rate in this area was severely restrained. We proposed the following three technical research directions: anti-collapse technology research, long-reach horizontal well drilling technology research and countermeasures of enhancing drilling speed segment by segment along the well.
