【 摘 要 】

Taking Bp block of the Middle East as the target, on the basis of Joshi's formula of horizontal well productivity prediction and the application of grey relevancy analysis on the average permeability, effective thickness, production pressure difference, oil saturation of reservoir and other major factors for the impact of the initial productivity of the horizontal wells, by means of obtaining the grey relational grade of influencing factors and the production of single well and optimal to optimize the combination of differential pressure, horizontal section length and other parameters, the effective exploitation of the oil field is achieved.
