摘要通过对世界上压扭性盆地的成盆机制、演化模式和油气地质特点分析，总结压扭性盆地具有6个方面的石油地质特征：压扭作用期间盆地的沉积速率较高，一般形成较厚的粗碎屑沉积，它们常构成很好的油气储集层：盆地的烃源岩往住来自于前压扭期砂成的富含有机质的岩石，但在强烈的压扭作用期间，在冲断带的前缘深坳陷（前渊）中有可能发育深水半深水相的烃源岩；压扭（张扭）作用期间形成的雁行式褶皱（包括背斜和断鼻等）往住是很好的油气圈闭；压扭作用易于成藏；压扭作用可以促进有机质的成熟生烃作用；压扭性盆地的周边冲断带是油气赋存的有利部位。 - Sponsored by costind space debris research devoted fund item - “ small space debris evolutionary mode study ( kjsp2001 - 0202 / 02 ) ” and 863 project item - “ space debris environment modeling and analytical applied technology ( 2002aa732152 ) ” , this paper simply introduces sdem ( space debris evolution model ) which was built up formerly ; then some overseas models which have been used before are compared with evolve4 . 0 breakup model . finally , some mitigation strategies are analyzed in the view of cost and technology . the main research contents of the dissertation are as follows : first , evolutionary mechanism study is the base of space debris environment evolutionary mode modeling
