With development of completion technology of horizontal well,selective completion is becoming a proven technique.However,theoretical study of optimization of open intervals of selectively completed horizontal well is very poor and there is no theoretical basis to implement the partial completion in the oil field production.The theoretical foundation of optimal selective completion in oilfield is not formed.In view of this situation,we discuss the effect on the productivity of selectively completed horizontal well,including segment number,dimensionless reservoir thickness,and open degree of well.The results indicate that the dimensionless productivity index increases with segment number.The open degree of the well has bigger effect on dimensionless productivity index.If the open degree of the well is a constant,the larger number of segments will give a higher dimensionless productivity index.Because of operating technique and operation cost,the number of segments is subject to optimization.The larger the open degree of the well will give a higher productivity of selectively completed horizontal well.The production rate does not increase with the open degree of the well increase when the open degree of the well exceeds a certain value.Thus,the open degree of the well is subject to optimization.
Key words： Horizontal well; Selective completion; Productivity; Optimization.
