摘要：
With the deepening exploration of oil and gas in deepwater with high temperature and high pressure conditions, there are various reservoir systems, which are complex and interlaced. Downhole complications occur frequently in the drilling process, which seriously affects the drilling safety. In this paper, combined the drilling example of deepwater with high temperature and high pressure well X1, dC index method and rock strength method are used to monitor formation pressure while drilling. The results show that the rock strength method is more accurate for pressure monitoring of deepwater with high temperature and high pressure wells, and it can provide a reference for subsequent monitoring of formation pressure in deepwater with high temperature and high pressure wells. © 2019, Editorial Department of Earth Science.
