M Blocks Of Kazakhstan Caspian Basin Oil And Gas Prediction Research

Seismic detection of oil and gas processing is based on 3 d seismic data,the application of Biot two-phase medium model of oil and gas detection technology.Biot two-phase medium model refers to the solid skeleton(solid phase)with pore and pore fluid filling in(flow)of medium.Biot theory is that the local shock wave through the two phase medium,produce relative displacMent between solid phase and the flow phase and interact,resulting in a second longitudinal wave.The second longitudinal wave and the wave reverse polarity and the speed is lower than the first,the second wave and the first after superposition,the original dynamic characteristics change.Oil and gas reservoir is a typical dual phase medium,theoretical research and a lot of actual application shows that on behalf of the oil and gas layers with low frequency energy of seismic records,the geophysical characteristics of the high frequency energy attenuation,this is the Biot theory and practice basis of oil and gas detection technology.According to the results analysis of drilling and logging interpretation of the G1,G6 and G2 wells in the region,the G1 wells in the sandstone in the T2+3 section of salt,the electrical measurement interpretation shows the oil layer;The interpretation results of 6 low potential and high resistance suspected reservoirs were found in the T2+3 layer of G6 wells in salt.The G2 wells are interpreted as oil layers in sandstone in the 922m~950m section of the salt tectonic layer.Therefore,sandstone reservoirs in salt,especially Triassic,Permian,and even Jurassic are non-negligible oil-bearing strata,and also the potential target layer of EM oilfield exploration.Based on the results of oil and gas detection,combined with the study area geology,drilling,construction and other research has carried on the comprehensive evaluation on the four reservoir,under carboniferous KT1,KT2 layer,salt(upper Permian and Triassic four horizon,district 15 favorable oil and gas prediction was proposed.According to the results of oil and gas prediction and reservoir evaluation,and advances some Suggestions on the 5 well placMent.
