Development Sequence Optimization of Fault-Block Oilfields Based on the Back Propagation Neural Network Model Improved by Imperial Competition Algorithm
A well-defined development sequence of each fault block in a fault-block oilfield is the prerequisite for field development plan design. Where there are very few fault-block oilfields, the method of numerical ...
