當前的測井分析工作仍像是一個遠離大陸的孤島,離地震解釋、地質建模和油藏描述這些“大陸”很遠,導致在測井與解釋之間經常發生數據延遲、缺失、缺乏連貫性和一致性等。測井部門與解釋部門之間缺乏充分的交流溝通。而哈里伯頓Landmark推出的DecisionSpace Petrophysics改變了這一局面。
哈里伯頓的團隊經過調研認為,測井解釋人員和地質綜合研究人員會花費30-40%的時間來搜集到所需要的正確的曲線,而哈里伯頓推出的端到端集成井下數據管理(BHDM)DataManagement(OpenWorks)一體化解決方案,可以大大提高用戶的測井解釋效率。

FEATURES
Rock Physics (Acoustic Waveform)
- Acoustic waveform processing and diagnostics window for easy data QC and pre-processing to identify and correct data issues.
- Acoustic waveform processing and diagnostics enables the user to process acoustic waveform data to determine compressional, shear, Stoneley, ?exural, and quadrupole wave slownesses as well as calculate cross-dipole anisotropy. The module uses semblance processing to generate correlograms which can then be displayed as variable-density log (VDL) and interactively picked to identify the various components of the waveform.
- Acoustic travel times then can be used in standard petrophysical analysis, e.g., porosity, multi-mineral solvers, as well as in Geomechanics, and Rock Physics modules to calculate elastic rock properties or synthetic seismograms.
- Geomechanics (Wellbore Stability, Pore Pressure, Sandpit3D – rock failure in sandstone reservoirs)
