The Application Status and Challenges of Managed Pressure Drilling Technology for Ultra Deep Well: Taking Shunbei Block as an Example

Abstract

Managed Pressure Drilling (MPD) is a kind of new drilling technology that has been effectively applied to pressure-sensitive formations of narrow safety density windows, multiple pressure systems. This paper summarizes the basic principles and various application scenarios of MPD technology. Taking Well A, Well B and Well C in Shunbei block as examples, the advantages of MPD technology in dealing with complex situations such as drilling, overflow and leakage in narrow density window formations are analyzed, and the key equipment, supporting technology and common abnormal treatment methods of MPD are proposed. The conclusions are as follows: MPD technology, . The application of MPD has provided a guaratee for the efficient development of the oil fields in Shunbei block and improves the drilling quality and efficiency of the block. The research results can effectively guide the managed pressure drilling operation, ensure the safety of well control, and enrich the theory of ultra-deep well drilling technology.
