Abstract:Cretaceous reservoirs in Yaerxia, Jiuquan Basin are the most important oil formations in this area. However the favorable reservoir distribution and sedimentary facies are unclear. Using multi-attribute analysis and structural interpretation tools provided by GeoEast interpretation sub-system, we predict favorable reservoirs and interpret structures. Based on our research, K1g13 channel sand bodies are the favorable reservoirs in this area. Lots of minor faults connect hydrocarbon migration pathway and improve physical property of reservior. GeoEast interpretation sub-system has many advantages in multi-attribute analysis, structural interpretation and structural diagram cartography. It can solve some complex geological problems in the hydrocarbon exploration.
