Research Of Detailed Structural Interpretation In The West Of Liulu Area Of Raoyang Sag

Raoyang sag is located in the middle of the Jizhong depression, the exploration area of about 6300 K m2, depression is the most enrichment of oil and gas exploration in Jizhong depression, has experienced more than 40 years, the remaining amount of resources is still larger. In recent years, along with the exploration of Raoyang depression degree unceasingly thorough, show that the structure of exploration and development is more and more important.Application papers 3D high resolution seismic data, combined with drilling and logging data interpretation constructed of fine, western Liulu region structure constructed with characteristic analysis.Based on the high resolution of 3D seismic data interpretation applications, profile using seismic data interpretation, coherent data volume interpretation, 3D visualization interpretation, horizon and fault interpretation and variable velocity mapping technology, the fine interpretation and structural stay western Liulu region of the 3D seismic data mapping, the implementation of the low amplitude structure, fault and the key blocks of a lot of small fault block and fault nose structure. According to the main faults and stratigraphic features of tectonic belts; and analyzed with a Neogene fracture plane and profile development characteristics of Liuxi structure belt, and the characteristics of the fault zone in different tectonic; summarizes the basic structural styles, the tectonic evolution of studied area features, reservoir types and hydrocarbon accumulation conditions. Finally, the fault block reservoir accumulation analysis combined with borehole data, the prediction of favorable area.
