Genesis and spatial distribution of interlayer in tight gas reservoirs: a case study from the Lower Cretaceous sandstones, Songliao Basin, China Yu Xiaoyu1, Zhang Penghui2,a, Zhang Guoyi1, Ding Fang2, Meng Ningning3, Li Jingzhe2, Zhang Ming2 1Research Institute of Exploration and Development, Jilin Oilfield Company, China National Petroleum Corporation, Songyuan 138000, China 2College of Resources Science & Technology, Beijing Normal University, Beijing 100875, China 3College of Marine Geosciences, Ocean University of China, Qingdao 266100, China azph010@163.com Keywords: Interlayer; tight gas sandstone, genesis, distribution, Cretaceous, Songliao Basin Abstract.
Physical interlayer belongs to a class of strata because clay content formations and sediment grain size changes, resulting in the lateral deterioration of the porosity and permeability, including fine-grained sandstone, siltstone and fine conglomerates contain more fine-grained material and poor sorting of sandstone (Fig.1B).

Design and analysis about twist-roller transmission based on the precision aerostatic guide way DENG Mingmin1, a, LONG Wei1, b (1Faculty of Mechanical and Electrical Engineering Department, Kunming University of Science and Technology, Kunming Yunnan 650500,China) admm007308@163.com, bdaifor@163.com Keywords: precise aerostatic guide way; twist-roller transmission; motion simulation analysis Abstract: At present the twist-roller transmission cannot meet the needs of adjusting the positive pressure and the twist angle in the meanwhile.
The model of virtual prototype can't achieve dynamics simulation after import.So the material properties of component should be defined and added constraint.

In optimal case fiber mat reinforced materials are isotropic, because the fiber bundles are ideally randomly oriented.
Describing the fibrous reinforcing materials is not an already solved problem therefore there are a great number of theoretical approaches and experiments in this area [6-13] while computer aided modeling of these materials is also a frequented researching field [14].
