The basic principle of using gas chromatographic fingerprint technique in reservoir development was that the changes of full hydrocarbon gas chromatographic "fingerprint" were concrete representations of heterogeneity of oil,it was mainly used for studying the reservoir communication and stratified productivity of wells.

Evaluation of reservoir wettability by means of conventional logging data;

An Identification Method of Conventional Log for Low-Resistivity Reservoirs in Jiyang Depression;

The mud logging properties of the non-sandstone reservoirs between salt beds in Qianjiang Depressed Area;

Transmission characteristic of low frequency hydrodynamic oscillation in oil layers;

The analysis of influence factor about low resistor oil layer in Z oil-field;

In view of the recognition difficult of the petroleum in in E31、E32、N22 reservoirs in the Qigequan Field, Chaidamu Basin, based on a great quantity of production information, according to the different lithology ,confirmed the recognition criteria of oil layer in different reservoirs by using the convergence between ILd and AC .

Determination of thermal parameters for oil reservoir using well testing data;

Calculating oil reservoir saturation by using Logistic cycle;

The driving pilot test of surface active agent is implemented at the layers V2-5 in the area B125 of Gucheng Oilfields, in which the purposes of injecting tracers are to understand the connection states between injection- production wells, the direction and speed of plane water flowing, and the states of heterogeneity in oil reservoir.

Reservoir displaying features and genesis for low resistivity oil zones of Dongpu sag;

The low levels in cutting show, abnormal showing value of gas logging and oil zone resistivity in Honggang area of Songliao Basin have brought considerable difficulties for distinguishing and evaluating oil and gas zones by using traditional mud logging means.
