A Flaking Method of Observing the Rolling and Stereo Shapes of Pollen under Optical Microscope;

A 3D finite element model of a rolling redial tire has been built with MARC software according to the practical structure of 195/60R14 tire.

In Xuzhuang oilfield,the structure is complex,the seismic data is bad,and the progressive development is difficult.

It is featured by fractural faults,severe multiple and igneous rocks,thus the technology of fine structural interpretation plays key role in progressive development of little fault block oilfield.

However, in 2001, great progress in progressive development has been made in this block by using advanced software, new technology and the combining of many technologies.
