Embodiment Construction
[0036] combined with Figure 1-8 , the present invention is further described: a kind of utilization deep seismic reflection data, confirms the preparation method of underground geological map of buried hill oil and gas field, and specific implementation scheme comprises the following steps ( figure 1 ):
[0037] (1) Use conventional seismic interpretation software such as Discover, Landmark, and Geoframe to draw the corresponding unconformity surface T at the top of the buried hill through seismic section interpretation 0 Or depth structure map, the base map for compiling the subsurface geological map of buried hill oil and gas fields.
[0038] (2) According to the deep seismic reflection data, analyze the complexity of structural changes in the inner buried hill and the occurrence changes of different strata, and determine the relatively stable area and the obvious change area of the stratum interface. When the mapping area is large and covered by a large When the baseme...
