Abstract

Abstract

The explosive fracturing technique is often adopted to produce and expand fractures due to its great shock waves, thus improving the low permeability of oil reservoirs. Based on the distribution characteristics of the explosive fracturing network and applying the Laplace transform and the Stehfest numerical inversion, this paper presents a new analytic mathematical production model for the complex-flow to an explosive fracturing well and obtains the formulas for the oil output under the constant pressure in different boundary conditions. On the basis of the model validation, this paper investigates the influence of the fracture network parameters on the output and the optimal design of the explosive fracturing. It is shown that the permeability of the fracture network exerts a great influence on the production. In addition, this paper offers an optimal design for explosive fracturing. The results from this study are expected to be significantly helpful for the optimal design of explosive fracturing and provide a rational design about the explosive quantity in low permeable reservoirs.
