Wangfu Area Denglouku Group Seismic Interpretation And Reservoir Prediction

This article through to Wangfu area Denglouku group of seismic, logging data analysis,the application software of landmark to the seismic data interpretation work; The Dengloukugroup of Wangfu area and the analysis of the sedimentary and reservoir characteristics,application of landmark and Jason software has carried on the research of reservoir prediction.Through the seismic synthetic record, well properly, according to the characters ofseismic reflection Denglouku group Wangfu area can be divided into three groups. Trackingformation on seismic work area, contrast explain four stratigraphy including Denglouku topand bottom, the third of Denglouku group and the second of Denglouku goup,interpretationaccuracy of4*4closed wave group characteristics of analysis of the paragraphs. To explainof Denglouku group of fault, fault emission characteristics were summarized. By means ofsingle well facies, the well profile facies, seismic facies analysis, summarizes the Dengloukugroup paragraphs deposition distribution characteristics.Through the analysis of core, logging data, reservoir sedimentary facies in this area is themain influence factors, thus the sedimentary facies control method is applied on the reservoirprediction, the application of post-stack high resolution seismic data, on the basis of fineseismic interpretation, extract root-mean-square amplitude and energy half-life seismicattributes, and the seismic attribute optimization and analysis of energy half-life attributes andwell matching rate is better. Therefore, uses the energy half-life seismic attribute, combiningwith the sedimentary microfacies map, sedimentary facies control of reservoir prediction, it isconcluded that the interval braided river channel, underwater distributary channel anddebouch bar microfacies distribution area is the development of reservoir sand body. Wangfuarea in Denglouku group sand body development a article belt in provenance direction; Givepriority to with thin layer sandstone, a greater difference between different facies belt. Interms of seismic inversion sand body prediction, the application of sparse pulse waveimpedance inversion and geostatistical inversion method, and finally selected geostatisticalinversion method to Wangfu area in Denglouku reservoir prediction. On the whole, the sandbody thick in the north thin in the south, thin in the west thick in the east, northernsandstone is continuous, southern sandstone form for small flake, sand body thicknessthinning, sandstone thickness distribution direction in conformity with the deposit.
