摘要
Abstract
In the large-scale hydraulic fracturing of shale gas production will be from a very high level of the early production quickly slipped to a low level and maintained for a long time,due to the production characteristics of shale gas and other oil and gas wells have obvious differences,therefore to predict the level of productivity evaluation and prediction of yield decreasing yield based on the great the difficulty. A prediction model of shale gas production optimization model is proposed in this paper,based on the model research of the Arps model,SEPD model and Duong model prediction,through the combination of SEPD model and Arps model,to abandon the two models with their respective defects,improve the prediction model of yield in different stages of the pro?duction of shale gas the accuracy of the. By using an example to calculate the surface,the optimized model can greatly improve the prediction accuracy of shale gas production,and the prediction error is only 4%.关键词
