Structural Characteristics And Reservoir Prediction Of The Pre-Jurassic In The Flame Mountain Area Of ??the Tuha Basin

With the deepening of oil and gas exploration,the complex mountain field has gradually become the hot spot of oil and gas exploration.Huoyan Mountains is a typical case in TuHa Basin facing with the complex geological conditions on surface area and underground Mountain,The exploration work based on fine structure and reservoir prediton will be focous of the future exploration in Huoyan Mountains.drilling in Huoyan Mountain TuHa Basin has gotten breakthrough in Permian,booming off the oil and gas exploration of this area again..Using the ideas of structural geology and sequence stratigraphy and reservoir geology the basis of high quality of seismic data,guided by the overall study and understanding,carrying out the region's structural geology and fracture characteristics:the pre-Jurassic mainlywent through four orogeny which behave as nose structure in west and residual from east to west and three locks from north to south.With the support of the structural interpretation technique,implementing the regularities of distribution of formation accurately and depict the regional tectonic and fracture characteristics.Using seismic attribute analysis,seismic inversion and reservoir prediton technique such as well logging processing get the implement reservoir distribution in Pre-Jurassic:Permian reservoir performance is a set of alluvial fan to lacustrine facies sedimentary system.Triassic reservoir performance is a set of braided river delta to coastal shallow-lake facies sedimentary system.The main source of sedimentary is from south east and south west.it can be said that the reservoirs are mainly distributed in YuBei tectonic belt.The fracture is the key to Pre-Jurassic reservoir,including distribution of favorable sand and ancient tectonic from configurarion of the relationship.Resarch have great significance to the deep exploration in TuHa Basin.
