Chengdao Eastern Slopes With Reservoir Prediction And Comprehensive Evaluation Of The Ancient Into The System

Recently years, using final structure interpretation and reservoirs inversion forecasted and appraised reservoirs of Chengdao oilfield. Getting the breakthrough of cognition of geography. Nowadays, we get the the industrial oil-gas at Dongying formation and Sha-hejie formation..According to the analysis of the present comprehensive data, Dongying formation and Shayi section are the major objects in the process of the next exploration, especially low part sandstone which developed in the channel under the structure ordovician condensate field. It has a bright future in the exploration.But the reflection of the fluvial channel sandstone on the seismic profile is so not obviously that it is so difficualt to trace,which brings the great trouble to the exploration.Adopted the seismic interpretive techniques of reservoir prediction for lithological oil/gas reservoir, including the seismic facies analysis based on waveform classification and sedimentary faices interpretation, the wave impedance constraint sparse impulse inversion, the seismic multi-attributes reservoir prediction and oil-gas detection, demarcating structure situation. After final structure interpretation of 377.55 km2, using drilling date demarcated synthesize document, established the accurate model of velocity of this area.The research start with well datum. description on the structure and traps get f ine detail, and by log data processing, stratigraphic correlation, final structure in terpretation, impedance inversion and 32D visualizat ion in terpretation,Well constrained seismic character inversion is a comprehensive techniques of seismic reservoir inversion.This techniques can integrate geologic and make-hole and seismic information etc,the inversion result include high frequency information of well and intermediate frequency information of seismic data.The result may forecast reservoir effectively.The basic idea of this techniques is pick-up seismic character ,and integrate geologic model.Via make use of main component analysis technique.On the basis of the reservoir evaluation and reservoir description, a very important exploration target reserve calculation and analyse the thereunder.RM(reservoir Modeling) is most popular and comprehensive oilfield description software package in China. It can be used to undertake prediction and disc Lipton space state of reservoir, physics character parameter and topographic and identify the reservoir distribution of vertical and horizontal and it's physical property change by seismic?logging?testing?chemical analysis data. It can evaluation the reservoir and can provide evidence for the reserve evaluation and parameter selection.The distribution rule and hydrocarbon potential features were carried out, and will directly be the next drilling target in this area.
