Description
Summary:With the deepening of deep water with HTHP oil and gas exploration, there are various reservoir systems, which are complex pressure systems and high and low pressure interfacing in the strata drilled at present. Downhole complications occur frequently in the drilling process, which seriously affects the safety of drilling operations. In this paper, we combine with the drilling example of deep water HTHP X1 well, 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 deep water HTHP wells, and it can provide a reference for subsequent monitoring of formation pressure of deep water HTHP wells.
