Aim To give scientific supports to the production by studying the features of strata and reservoir in middle base-level cycles of Chang 6 reservoir set in Panguliang Oilfield.

Methods Taking the Chang 6 reservoir in Pan′guliang,Jing′an Oilfield as an example,to fit the lithologic characteristic and the electronic data according to the analysis of the cores and evaluate the data in the well log curve of the interlayer of the underwater distributary channel.

Analysis of high-resolution sequence stratiggraphy of Chang-6 Oil Reservoir Set;

Through building an exact geological model which can show the geological character of Panguliang Chang-6 Reservoir,analysing and studying the strata frame,sedimentary microfacies,framework sand,quality parameter and reservoir heterogeneity,the assured precise 3D geological model was built with the software of GMSS.

Study on the law of water cut increasing in Panguliang area of Jing an oilfield;
