Interpretation And Structural Characteristics Of Seismic Data Of Suning Dawangzhuang Buried Hill Belt

Buried hill is an important exploration area in Jizhong depression. With the continuous exploration, large size, shallow burial, simple type, easy to find oil and gas reservoirs of the buried hill have been found out. At present, buried hill exploration has entered the subtle and meticulous exploration stage. Buried hill reservoir is most found in Raoyang Sag of Huabei Oilfield, and the scale of buried hill reservoir is the largest. Suning- Dawangzhuang buried hill belt is located in the middle of Raoyang Sag, between two transverse structure belts of Balizhuang and Dawangzhuang, which are located in Hejian Wobei Source trough range. It is a compound oil and gas accumulating zone of the central uplift of Raoyang sag. It is rich in oil and gas resources, and the potential of exploration. is high. The target recognition of this area has guiding significance of buried hill deepening exploration in Raoyang sag. With transverse basement strata changes rapidly, the buried hill trap implementation, oil source and oil supply window conditions are extremely complex. This paper mainly based on new treatment 3D prestac K depth migration of seismic data of Suning Dawangzhuang buried hill belt. To develop the study of seismic data interpretation in this area, fine horizon calibration technology, structural oriented filtering technology and coherence cube technology of fine 3D seismic data interpretation techniques are used. The seismic reflection characteristics of buried hill formations are clarified. The distribution and rules of buried hill formations are found out. The study on structure and fracture system of buried hill are completed. The structure and tectonic evolution history of buried hill are analyzed. The different stages of tectonic movement can effect buried hill formations and traps. The geological comprehensive evaluation of the newly discovered traps were done, and a batch of buried hill traps were implemented, which lay a foundation of further exploration research.
