The Hairlar - tamuChage Basin is superpositioned on the volcanic rock construction above the Inner Mongolia - DaXing' anling on the Paleozoic collision Orogen in the Meso-Cenozoic terrestrial rocks and volcanic rocks with construction of the petroliferous basins.Its internal for two three -long au pattern of the Tectonic Framework,Bei'er depression locates in the central depression of the structural belt, is a super-East West broken off a single-faulted half graben rift.Bei'er depression in the evolutionary process experienced a Rifting period,Fault-depressed Diversionary period,Depression period,and several other processes.During the period it received each direction the stress action,formed the extension,the extrusion in the Bei'er depression interior,to strike-slides,the inversion and so on many other kinds of structural styles.Because the period of tectonic movement led to the interruption of these structural pattern in the distribution of Bei'er depression formed within a certain characteristics.This paper through the Bei'er depression internal northern,central and southern measured three main in-lines of research on these structural style into a systematic and summary。Study the structural characteristics and tectonic evolution of history and combine the sequence characteristics of tectonic movement of the sedimentation of the reservoir and the impact of the distribution control the different structural location and forecast the favorable exploration area of the future exploration on Bei'er depression,and will analysize the Bei'er depression petroleum combination the characteristics of the Source Rock in the sedimentary period and its horizontal distribution.Use of drilling,well logging,and other data with the seismic section summarizes the reservoir type in the Bei'er depression.
