DETECTION OF HYDROCARBON POTENTIALS IN SHENGBEI AREA OF TUHA BASIN
|
Abstract:
The detection of hydrocarbon potentials is to recognize the fluid type of reservoir directly by using the different seismic response of oil & gas strata from water layers or dry layers.Detection work can be carried out in two steps: recognition and tracking.Concrete techniques for hydrocarbon detection include seismic attributes and geological analysis,data decomposition,multiple attributes optimization and prediction by integrating various seismic attributes.There are 10 wells,including Shsh3,Shb3 and so on,within Shengbei area,thereinto two oil & gas layers,J_3k and K_1l,have been found.J_2q is another important hydrocarbon stratum in the area and high yield layers have been found at the stratum in many wells in nearby areas.Hydrocarbon potential detection technique by integrating multiple attributes has been used at these two strata to determine their oil-gas distribution respectively.Oil & gas reservoirs have been found in the newly drilled well Shb16 in detected favorable region,proving the accuracy of the detection result.
