This paper collects the latest data in different fields of geological researches on mid-Asian area such as regional geology, Bouguer gravity, aeromagnetic, satellite magnetic, DEM, seismic tomography, modern earthquake, isotope age, deposit occurrence. In this paper, GIS, gravity and magnetic data processing software, and advanced image processing software are employed for the first time to analyze and process large amount of complex data, from which much helpful information were obtained. Such information offered reliable basic data for doing assessment and interpretation, therefore make possible to put forward, from geophysical point of view, a set of new views and methods in studying of tectonic of mid-Asian area.

Using maximum flooding surface and local explosure erosion surface as the correlation framework surface in the 4-th hierarchical base-level cycles, sand-body in the 3-th hierarchical base-level cycles formed in the 4-th hierarchical base-level cycles may be correlated layer by layer. The law of the sand-body and the characters of reservoir heterogeneity formed in the 4-th hierarchical base-level cycles are discussed. The study shows:①During early period of the 4-th hierarchical base-level cycle rising, subaqueous distributary channel formed, continuously stacked vertically, and migrated in limit range laterally, and channel sand-body stretches farther longitudinally, and lacks interbeds of mud rock and siltsand in sand rock, reservoir heterogeneity is relatively weak.②During mid-period of the 4-th hierarchical base-level cycle rising, subsaqueous distributary channel migrated actively, channel divided and converged strongly to form netted sand-body and sand sheet mainly, but interbeds of mud rock and siltsand increases gradually in sand-body, reservoir heterogeneity increased.③During later period of the 4-th hierarchical base-level rising and early period of the 4-th hierarchical base-level falling, reservoir sand-body was poor, and only form thin sand-body of subsaqueous distributary channel, subsaqeuous creveas and distal mouth bar, sand-bodys are surrounded by mud and silt rock.

5Oil and gas were controlled by the structure formed by superposition of tectonic movement in the early and late Hercynian which resulted in palaeogeomorphology and degree of fracture growing. The latter decided the flowing direction of palaeocurrent and the degree of corrosion,which is the main factors of karstification.Especially,the superimposition of palaeostructure and Akekule uplift is the most favorable area for karst and fracture growing.The ubiquitous high angle fracture made all kinds of vugs into a large scale storage,so the fracture-vug system was divided into some blocks in the main oil zone on the plane.
