【摘要】 1993年李传亮提出的带隔板底水油藏油井临界产量的计算公式中不含油井打开程度的参数,即没有考虑油井打开厚度的影响。但是实际油井通常不可能刚好射孔到隔板处,因此,此公式还可以进一步改进:即在油井临界产量中附加一个由于射孔井段底端和隔板之间距离产生的油井临界产量。通过实例证明,经改进后的油井临界产量更符合油藏实际。更多还原

【Abstract】 In 1993, a formula for critical production rate of oil well in bottom water reservoir with partition board was proposed by Dr. Li Chuan-liang, but this formula did not contain any parameter of well penetration, i.e. did not take the perforated thickness into account. it is hard to just perforate the partition board of well in fact, so a modification for it should be made on Li’s formula by adding a critical production rate contributed from the bottom of performed interval to the partition board. Case study indicates that the improved formula is more suitable for the real reservoirs than before.更多还原
