X. House Broken Trapped Solitary - After - Eight Regional Cretaceous Reservoir Characterization And Hydrocarbon Prediction

This paper studied the reservoir inhomogeneity and oiliness by using the technology of reservoir description in the aspects of deposition system and microfacies characteristic , 3-dimensional distribution characteristic and configuration , etc. Based on electrofacies analysis, microfacies analysis, seismic facies analysis and 2D-3D seisemic fine structure interpretation, the research of reservoir description of main hydrocarbon reservoir in the region of interest was done, aming at the characteristic of quickly-Changing facies of main oil and gas reservoir and strong inhomogeneity, etc, in the researched area, taking petroleum geology, structural geology and sedimentology as theory instruction, applying to multi-disciplinary correlation information such as geology , physical prospecting, well logging , test and so on , using the advanced specially-handling of seismic information and explaining technology. Namely the reservoir description carried on contrast tracing the reservoir subzone , the reservoir fine structure interpretation, the microfacies, the comprehensive evaluation of reservoir by log, reservoir model building and the reservoir lateral forecast and the oil-gas forecast.The article creatively proposed the trinity method of log- seismic inversion - geologic interpretation, which was used for reservoir forecast. Firstly the log information was used to study geophysics response characteristic to sands , and define the relations among sands and its cap rock and the wave impedance value. Then the fine demarcation to the reservoir was got, using the technology of fine demarcation of reservoir, together with the existence data of the drilling well, log, geology, withdrawing the seismic cross-section wavelet passing thorough the wells and inversing the...
