【摘要】 通过对凝析气藏水力裂缝伤害的机理分析,提出一种计算模型,预测凝析气藏压裂井的产能,量化气体渗透率降低对产能的影响,进而优化凝析气藏水力裂缝设计。这种模型的独特性主要倾向于必要的裂缝长度,目的是弥补凝析液析出产生的伤害。该模型也为准确计算用来优化凝析气井产能的压力降提供了依据。更多还原

【Abstract】 Through the analysis of damage mechanism to hydraulic fractures in gas-condensate reservoirs,we are presenting a model that predicts the fractured well performance in gas-condensate reservoirsl,and quantifying the effects of permeability reduction.Furthermore,we present fracture treatment design for condensate reservoirs.The distinguishing feature primarily affects the required fracture length to offset the problems associated with the emergence of liquid condensate In addition,guidelines for the calculation of the appropriate pressure drawdown during production to optimize well performance are provided.更多还原
