摘要
Abstract Horizontal drilling and hydraulic fracturing can effectively increase the contact area between fractures and reservoir, which are important method to realize the economic and efficient development of unconventional reservoirs. In the traditional fracturing scheme design, “sweet spots” guide the fracturing construction. However, due to lack of the interaction process of using engineering data to validate and correct the original data until the final convergence with reality, it cannot be dynamically optimized and matched in time. To overcome above shortcomings, this paper proposes a new network fracturing scheme design workflow based on the integrated geological-engineering integration (GEI) method. The tight carbonate reservoir X layer of oil field A in the Middle East is set as a case. A comprehensive sweet spot evaluation method is established using the partial correlation coefficient analysis method, considering the physical properties and fracturing performance of reservoir. The comprehensive sweet spot model is calibrated and optimized using experimental data, stimulation parameters, well tests, and production data. Based on the comprehensive sweet spot model, the quadrant chart is plotted and varied single well fracturing scheme designs are implemented for different quadrant areas. The numerical simulation results show that it can improve the development efficiency of unconventional reservoirs.
