Application of Pressure Data Analysis in Tapping the Potential of Complex Fault Block Oilfield

Abstract

The B oilfield in Bohai Bay Basin is the fluvial facies sedimentary, reservoir thickness varies rapidly in lateral direction, and what is worse the fracture system is very developed, petroleum reserves are small within a single block. Due to the poor quality of seismic data, the sealing of fault and reservoir connectivity is unclear which directly affect the understanding of reserves and adjusting injection-production well pattern. This paper introduces the working principle of StethoScope, and use formation pressure testing by StethoScope analyzing the fluid system and reserve scale, which can indirectly judge the sealing of fault and reservoir connectivity. This method provides a reliable basis for well pattern deployment.
