摘　　要：通过严密的公式推导,充分考虑表皮系数的影响,对水平井产能计算公式Borisov公式和Joshi公式进行改进与修正。应用改进后的Borisov公式和Joshi公式对海上油田某水平井的初始产能进行评价,计算产能与实际产能基本一致。The Borisov formula and Joshi formula for the horizontal well productivity calculation are improved and corrected,through the rigorous formula derivation,fully considering the influence of the skin factor. The initial capacity of a horizontal well in the offshore oil field is evaluated by using the modified Borisov formula and Joshi formula. The calculated production capacity and the actual production capacity are basically consistent.
