Optimization method of fracturing treatment parameters driven by surrogate optimization algorithm in tight oil
摘要
Abstract
The optimization based on fracture propagation usually maximizes the stimulated reservoir volume,but can-not evaluate the economic benefits.The optimization based on numerical reservoir simulation typically assumes that the fracture is bi-wing planar shape,which is difficult to achieve in on-site construction.Therefore,this paper takes the maxi-mum economic benefit as the goal and establishes a mathematical model for the optimization of tight oil fracturing treatment parameters.Based on the multi-mechanism numerical simulator of tight oil integrated fracturing and production,the char-acteristics of the optimization problem are clarified.The solution plane has many peaks and high roughness.The numerical simulator is computationally expensive.Then the optimization algorithms are compared using the fracturing optimization problem and the test function that fit this characteristic.The surrogate optimization algorithm is recommended.In this way,a fracturing treatment parameter optimization method is proposed.Then field application is conducted.Results show that compared with genetic algorithm,stochastic simple approximate gradient algorithm and artificial protozoa optimizer,the surrogate optimization algorithm is faster and more accurate in finding the optimal value.With limited simulation runs,in comparison with simultaneous optimization,the hierarchical optimization strategy can not only achieve higher economic benefit,but also achieve higher oil production.Therefore,it is recommended to adopt a hierarchical optimization strategy to carry out the optimization of actual reservoirs.This method provides an efficient tool for optimizing fracturing treatment parameters.关键词
