Abstract
|
Fractured reservoirs occupy considerable proportion in China, the oil and gas production of fractured reservoirs accounted for more than half of the entire production, and it will account for more than two-thirds of the oil and gas reserves in the future, so it makes the research of fractured reservoirs more practical significance.With the widely use of reservoir stochastic modeling technology and the rapid development of computer technology in the1990s, fractured reservoir research was gradually being quantified.The discrete fracture network model and the composite model of gradually development in recent years are becoming the representative of the classic.The natural fracture occurrence in the reservoir can be well described through the DFN, as well as the relationship between matrix and fracture, however, there are still many problems in practical application, Such as the strong randomicity of the fractures whose development are controlled by many factors, the difference of the data in different position is big, so it is very important that how to control the space where fractures developed.The fractured reservoir modeling is based on the general DFN technology with structure prediction as constraint condition, taking An Sai oilfield as an example, and both the geometry shape and the flow behavior of fracture system are effectively described.The reliability of model is high and also the fracture data can be used as an important basis for the reservoir numerical simulation, according to the validation by dynamic data.
