Fault Control on Hydrocarbon Accumulation in South Beier Sag

Abstract:

In order to research the relationship between the fracture and reservoir in the south beier sag, using the method of integrating theory with practice, Through research fracture development and system partition and anatomy of the reservoir shows that the fracture on the formation of the reservoirs mainly the following two aspects, First,the fracture provides migration conditions for oil and gas namely 1 early extend fracture make 1st member of Nantun group surcerock and the south 2nd member of Nantun group reservoir side joint, which is beneficial to oil lateral migration; 2 the long-term development fracture for secondary reservoir formation provides favorable conducting channel; Second, Fracture provides shield condition for oil and gas accumulation, namely 1 reverse fault "back on" low uplift area native reservoir accumulation are controlled; 2 reverse fault - fan control assembled parts of the secondary hydrocarbon reservoirs.
