FRACTURE SIMULATION AND PARAMETER OPTIMIZATION OF HYDRAULIC FRACTURING ON GUANDONG SHALE OIL IN DAGANG OILFIELD

ABSTRACT
The Dagang Oilfield has developed a multi-layered 3-D technology for terrestrial shale oil, but challenges such as multiple faults, vertical bedding, superim­posed oil-bearing layers, and limited vertical modification lead to inconsistent effectiveness. To address this, this study establishes a 3-D geological model of the Guandong shale oil (GY) block, integrating fracture parameter inversion from construction pressure and logging data, calibrated through historical matching. It examines fracture morphology, well spacing, horizontal section length, and fracture parameters, optimizing well patterns and fracturing parameters using an or­thogonal experimental method. Additionally, an evaluation system combining the analytic hierarchy process and fuzzy comprehensive evaluation provides guidance for efficient shale oil reservoir development.
