Research and application of reservoir structure in thick oil layers of fluvial facies in Gudao Oilfield;

Study and utilization of interbeds in K_2t_1~2 thick oil layer in Chenbao oilfield;

Multidisciplinary study and potentiality analysis on thick oil layers in Lamadian Oilfield;

Classification of intercalation and the longitudinal remaining oil distribution pattern in reverse rhythm thick reservoir-taking 8-15 sand bodies of Es_2 in Shengtuo oilfield as examples.;

Study on the influence of intercalation on remaining oil distribution in thick reservoirs

An inter-layer 3D static model is established for thick reservoirs.

Positive analysis of the effect of drilling investment and crude oil price on economical reservoir thickness;

By comparison and calculation of the factors affecting the productivity,such as drainage area,reservoir thickness,horizontal well length,the anisotropy ratio of reservoir permeability,it indicates that the changing trend of productivity with every influence factor from Chen s formula is accordant with Joshi s.

Based on the oil layer thickness in monitoring well, a method is adopted to est.

It also analyzes the influence of plugging agent type,oil layer quantity,oil layer thickness and construction technology on the profile control effect.

The results showed that the thickness distribution of ink film is in accordance with normal distribution and its standard deviation which represents the uniformity of ink film thickness becomes smaller along with the increase of the smoothness, or the decrease of the roughness of the printing paper.
