3D Modeling of Fracture-Cave Reservoir from a Strike-Slip Fault-Controlled Carbonate Oilfield in Northwestern China

A giant strike-slip fault-controlled Fuman Oilfield has been found in the Ordovician fractured carbonates of Tarim Basin. However, conventional seismic methods are hardly able to distinguish reservoir and its connectivity ultra-depth (>7000 m) carbonate fault zones. We propose thin-likelihood tensor-thickness process describe fracture network large cave reservoir, respectively. Together with two for 3D visualization fracture-cave reservoirs, we had an application ultra-deep well deployment Oilfield. The results show that can be 3D-imaged more clearly than methods. distinct segmentation by assemblage Furthermore, modeling is favorable description along There three models: core-, damage zone- overlap zone-controlling reservoirs This revealed variable related maturity segmentation. method widely used subsequent optimization, suggesting a economic oil exploitation reservoirs. case study not only useful complicated but also helpful employment provide support target evaluation optimization
