With drilling industry facing increasing challenges,intelligent and auto-matic drilling technologies is continuously developed and has changed the way of drilling dramatically.One key component of intelligent and automatic drilling system is the drilling design & analysis software.Traditional drilling software usually store its data in relational databases,which has indexed rows and nice conditional query speed,but when facing large amount of sequential discrete data records such as real-time logging data,store them as relational tables will cause a disaster in query speed.In real-time decision-making scenario where simulation code is running every millisecond,these drawbacks is never affordable.This paper introduces a brand-new design methodology of database to store and persistent the data produced by drilling analysis software,which will increase the maintainability of data-schema and data corn-speed.Numerical experiments are carried out to prove the performance bring the new technology.
