Carbonate Reservoirs In The Loess Plateau Of3D Seismic Exploration Technology Research In Su203

Different areas in the Ordos Basin were found in the reservoir or natural gas reservoirs,major Changqing gas field discovery well Shancan1well is the following PaleozoicOrdovician carbonate reservoirs, the Lower Paleozoic carbonaterock salt reservoir explorationdirection gradually south and east loess plateau area extends the newly discovered high-yieldnatural gas reservoir in Ordovician carbonate reservoir, have embarked on a large scale for thecarbonate reservoirs of the loess Plateau3D seismic exploration technology research. Formeda complex loess plateau area of high-precision, the wide azimuth three-dimensionalobservation system design technology, the concept of change of the complex obstacles andfine loess lithology and aqueous investigative techniques; detector selection and safety andenvironmental protection emulsion explosives testing; research basedexplosion safe distance,reducing the shot point blank point and the effect of a single shot acquisition; the loessPlateau GeoEast static correction techniques in combination, through pre-stack multi-domainnoise pressure well control processing, prestack time migration technology applications, andachievedexploration, to further promote the loess Plateau carbonate reservoirs in the processof three-dimensional seismic.
