在快速沉降的新生代盆地，由于泥岩快速生油而又难以排放，形成局部异常高压带。
Local abnormal high pressure zones are formed in swift burial Cenozoic basins because mudstone generates oil quickly and releases with difficulty.
快速沉降相的存在使我们可以更精确的确定生油的时限。如果考虑异常地幔的固化效应，则开始生油的时间要比岩石圈简单冷却情况下的生油时间早2-3倍。
If the effect of the anomalous mantle solidification is taken into account, the starting point of oil generation is 2-3 times earlier than in the case of simple lithosphere cooling.
认为沉降器汽提段穿孔部位均发生在汽提蒸汽附近，汽提蒸汽流化异常状态是造成穿孔的根本原因。
It is concluded from the analysis that the culprit of cracking is the mal-fluidization of stripping steam as all the crackings of stripping section have devel - oped near the steam.
