【Abstract】 Based on the optimization problem of designing the trajectory of three dimensional horizontal well,we establish an optimal control model,in which the primary constraint conditions are nonlinear ordinary differential equations.Using the method of uniform design to choose initial points,we decompose the admitted region into finite subregions,among which we construct the improved Hooke-Jeeves optimal algorithm. Several practical results show the validity of the model , algorithm and software we finished.更多还原
