Sedimentarfades Division And Distribution

Tarnum SAG, north-south partition characteristics, from west to east into western slopebelt, buried fault zone, central Western au, AU, central fracture of buried Hill belt, AU,eastern fault nose structural belt in the east, development on a major fault zone in Anticlinetraps, broken nose, broken blocks; North-South partition is characterized by each of thethree-level structure with further refinement into a four-level structure.Tarnum SAG is a wide slow Super half-Graben fault depression of breaking from east to west, this paperaims at describing the Tongbomiao group reservoir oil-gas enrichment regularity and reservoir formingmodel. According to the regional geological features of the basin, incorporated rock fabric, sedimentarystructures, seismic faces indicators and sedimentary tectonic background material, the main controllingfactors were investigated with the formation and distribution of reservoir. Then sedimentary faces andsedimentary micro-faces model was established.Tarnum SAG is a wide slow Super half-Graben fault depression of breaking from East toWest, Paper to the copper Bowl Temple reservoir oil-gas enrichment regularity and reservoirforming model for target, Integrated use of Petrology of sedimentary rocks, PetroleumGeology, geochemistry, geophysics, and other disciplines of knowledge, In collecting andcollating a lot on the basis of the first exploration of practical information, Starting from basingeological feature of the region, Discussion on the main control factors of reservoir formingand distribution. Control of hydrocarbon accumulation in sedimentary environment of thereservoir quality and, Oil and gas distribution and sedimentary environment of reservoir isclosely related to quality, different depositional system, the reservoir of the same quality,resulting in oil and gas reserves are not the same. Observation-based study on sedimentaryfacies of the core is the basis for research and interpretation of seismic data in sequence, thesingle interface indicates the variation of the strata of sedimentary facies and sequence andseismic interpretation provided an adequate basis and constraints. Fan Delta facies sand-bodyfront Asia development site is within oil and gas-rich region. And on this basis identify twogood and two in the direction of favorable exploration areas for exploration.
