High-quality Reservoir&Range Of Profitability Pre-determination On Phoenix Area,Chad

Along with the more and more careful exploratory development, the exploration activity is turn to low amplitude structural reservoir, stratigraphic reservoir and lithologic hydrocarbon reservoir. Common prospect can not to meet the needs.WA&WF&HD Seismic technology is a new technology in recent years, what is means wide azimuth, wide frequency and high density Seismic. The WA&WF&HD Seismic data consist of Frequency and azimuth information what is lack of traditional seismic data, and can be used for a variety of technical computing. With the continuous deepening of exploration and development of oil and gas, the key exploration targets have been from the early simple structural oil and gas reservoirs to go looking for a relatively complex structure of oil and gas reservoir and subtle stratigraphic and lithologic oil and gas reservoirs and some residual oil and gas reservoir, the complex oil and gas reservoir formation and occurrence of concealment and complexity mainly lies in the type of complex and diverse, structural shapes, also widely distributed, but the reservoir is generally thin, poor, reservoir heterogeneity is strong continuity. Therefore, we need more accurate seismic data to of these reservoirs are more accurate description and requirements collected seismic data as far as possible the sampling range wider, bands contain more low frequency and high frequency information of the sampling point density higher. Resulting in the formation of WA&WF&HD seismic data can be more fine seismic interpretation, to facilitate the use of anisotropic, prestack AVO effect, azimuthal velocity spectrum analysis, OVT interpretation technique is more accurate and more intuitive method to better for fracture prediction and hydrocarbon detection.The burial hill on Phoenix survey is almost Granite burial hill, with the reservoir of hole and fractured reservoir. Through the research we can found effective technical to predict of such reservoirs, at the same time, we can evaluate the effect of the WA&WF&HD seismic data at burial hill reservoirs.Through the research on the characteristics of oil and gas reservoir and the distribution of reservoir in burial hiss of this area, the effective research methods are formed, and the other similar projects can provide reference for other projects.Study on this issue, use WA&WF&HD seismic data in the bedrock buried hill reservoirs with high quality and favorable area prediction of supporting methods, forming a set of effective use of WA&WF&HD seismic data to conduct a series of buried hill reservoirs with high quality and favorable area prediction technology has been explored.
