,is erected on dental morphology of m2～m3 and a central lower incisor,which were collected from the early Middle Miocene Halamagai Formation of Tieersihabahe in the northern Junggar Basin of Xinjiang Uygur Autonomous Region,China.

Forming Mechanism of Hydrocarbon Reservoirs of Halahatang Formation in Yuqi Block in Akekule Arch,Tarim Basin;

The characteristics and influential factors of Halahatang Formation reservoir in Yuqi area,Akekule uplift are studied by means of core inspection,casting thin section,cathodology,SEM,porosity and permeability analysis,mercury intrusion method etc,hydrocarbon charge and accumulation law are studied with the technologies,such as fluorescence thin section and fluid inclusion.

Reservoir characteristic study of Karamay formation in Liu-dong district of Karamay Oil Field;

Point out that the Karamay formation is not the alluvial fan facies as the predecessor said,but fan delta sedimentary.

because of the poor recognition of the reservoir feature, inaccurate analysis of reservoir damage causality, the acid type and acid formula be not fit for the reservoir, The acidizing measure of Kelamayi oilfield kexia group T system sandstone reservoir is not effective, the productivity is enhanced in the near future.
