Tu Chinh - Vung May basin area is the deep waters offshore, an area of approximately 150,000 km2. Search activities in oil exploration in the area in recent years has been more interest and seismic surveys and geological studies and evaluation of mineral potential, especially oil and gas potential. Characteristics of the geological structure of Tu Chinh - Vung May basin and surrounding is very complex, not yet shed light on the overall picture of the geology and mineral potential. Also sea water depth in the area varies from several tens of meters at the beach several hundred meters underground and deeper from 1,000 - 2,800 m also affect survey work and research. In this article the authors sum up and analyze geological structural features of the area Tu Chinh - Vung May is based on the results to the present time to address areas of potential oil prospects gas. Result interpretation 2D seismic data for the entire area Tu Chinh - Vung May basin maps shown through the establishment of new structures include: a map Pre-Tetiary Basement, Oligocene, Miocene lower, middle Miocene and Miocene on. The main fault systems include: Systems North East - South West, A system of longitude, A system of latitude and systems North West - South East. Based on research, meta-analysis of geological structures, the authors separated the areas of Tu Chinh - Vung May into 6 main structural units: Zone of Nam Con Son basin northeast
Zone of Spreading bottom of the East Sea
High zone of Tu Chinh - Phuc Nguyen - Phuc Tan
Vung May basin
High zone of Da Lat - Da Tay and High zone of Vung May - An Bang and regional oil and gas potential high northeast Nam Con Son basin and Vung May basin.
