低渗透致密砂岩气层产能预测方法研究
Capacity Prediction Methods of Tight Gas Sandstone Reservoir with Low permeability
摘要
Abstract
T he gas reservoir property is poor and the percolation mechanism is complex in the eastern part of Upper Paleozoic in the Ordos Basin . It is difficult to determine the gas productivity index . And the relationship between gas abundance and porosity‐permeability is ambiguity . T herefore conventional productivity prediction method is not effective . Based on petrophysical experiments and wireline log data ,analyzed are the differences of different fluids in acoustic and elastic parameters .Then the sensitive parameters of the gas reservoir is optimized and gets the parameters with the Xu‐White model and Gassmann function .Lastly the prediction model is established on the basis of sensitive parameters . T he research concludes that bulk modulus is highly sensitive to the capacity of gas reservoir .And obtaining elastic parameters does not rely on the physical properties of gas reservoir .This method facilitates the capacity prediction of tight gas sandstone reservoir .关键词
