It is indicated from drilling that Chepaizi swell is characterized by multiple oil-bearing zones,multiple reservoir types and multiple oleaginous grades.

On the basis of study of the geologic structure,sedimentary microfacies and reservoir property,it can be concluded that the Mesozoic reservoir types in Zhidan oilfield include structural-lithological reservoir,structural-hydrodynamic reservoir and lithological reservoir.

The efficiency of sidetracking is closely related with reservoir type and sidetracking target.

Study on sedimentary characteristic and oil reservoir types of lower Ed in the eastern slope of Chengdao oilfield;

Classification of reservoir types of Budate group in clastic buried hills of Sudeerte structural zone,Hailaer Basin;

The oil/gas reservoir types in Wuerxun-Beier faulted-down depression and their exploration methods;

Furtherly,according to structural positions and related reservoir types,hydrocarbon accumulation models can be divided into five types,including the main uplift body,the uplift steep slope,the uplift gentle slope,the inter(intro)-sag highland and th.

The main reservoir types were anticlinal reservoir, fault reservoir, lithologic reservoir, heavy-oil sealing reservoir and composite reservoir in Wuerhe-Xiazijie Area, and heavy-oil sealing reservoir was a typical one.

Based on investigations of accumulation types and distribution regularities in the Dawanqi oilfield,it is pointed out that,this oilfield is controlled by various geo-factors and characterized by multiple trap and reservoir types.

The results indicate that there is noticeable otherness in the characteristics of source rock,reservoir rock and forming mechanism of oil pools,though reservoir types both of them are all lithologic or structural-lithologic.
