For the sake of complex analysis requirements of drilling fluid analysis system, this paper proposes a multidimensional data model and implement the solution of data mart due to the analyzing weaknesses of conventional information system. Since the database system is only applied to undertake the daily manipulating application of raw data, and supports simple works of search and statistic, however,...
Drilling fluids play a key role in the minimization of well bore problems when drilling oil or gas wells, usually the design of drilling fluids is depended on many experiments with experience. Rule-based and case-based reasoning drilling fluid system was designed with theory of expert system by some researchers. But it is very difficult to get to know and express precious relationship between drilling...
Mud pulse telemetry is a method used for measurement-while-drilling (MWD) in the oil industry. Information (tool-face orientation, temperature, pressure etc.) which is modulated by means of pulse positioning modulation (PPM) is sent from the bottom of the well to the surface by means of pressure waves in the drilling fluid (the drilling mud). Due to the influence of kinds of noise, the noise removal...
