摘要
近井地带的表皮系数,是评价油气井产能和完井效率的重要参数。然而,利用压力恢复曲线确定的表皮系数,是一个总表皮系数。它应包括:打开程度表皮系数、射孔密度表皮系数、高速湍流表皮系数和泥浆污染表皮系数。综合有关的成果(参考文献[1]、[2]、[3]、[4]、[5]、[6]),提出了气井表皮系数的分解方法。通过实例应用表明,提供的方法是有效的。
Skin factor of near wellbore zone is an important parameter to evaluate productivity and completion efficiency of oil and gas wells.However,the skin factor determined by pressure buildup curve of gas well is a total skin factor which includes penetration degree skin factor,perforation density skin factor,high velocity turbulence skin factor and mud damaged skin factor.Based on concerned references眼1-6演,a decomposition method of the skin factor of gas well is proposed in this paper.The effectivity of the method is indicated by case applications.
