Abstract：To ascertain the structural details，reservoir geometry，regular hydrocarbon distribution in T2 X 1 region by not only using the drilling and log data but also doing reasonable development seismic exploration is an important matter which we must achieve in rolling exploration in the region. Horizontal reservoir prediction in this region has been finished in following steps..Preliminary work was conducted，which included the construction of 3-D velocity field，the comparison between log curve and synthetic seismogram(or seismic traces)，and log-restricted inversion..The migrated data volumes of high and low frequency seismic data were produced by taking different processing methods，and they were used in detailed structure interpretation.·Accurate structural map was drawn after time-depth conversion using varying velocity.·Hydrocarbon prediction ;teas done by introducing 8 kinds of seismic charac teristic parameters which are sensitive to hydrocarbon existence.·T}e:}elopment boreholes were designed by overall considerations of some factors in strorture，reservoir，hydrocarbon prediction and so on.·Prediction result was checked by three boreholes，which found maximum error of llm and minimum error of 3m.
