【摘要】 根据裂缝 孔隙性油气藏损害特点出发 ,建立新的裂缝 -孔隙性油气藏数学模型 ,该模型考虑了裂缝与基块之间窜流表皮系数Sma ,通过对数学模型的求解 ,分析了Sma对压力动态的影响 ,表明Sma对压力不稳定曲线的影响严重 ,对现场资料解释的实际应用中取得很好的效果 ,对于裂缝 孔隙油气藏的试井解释和损害评价都具有重要的指导意义。更多还原

【Abstract】 According to characteristic of formation damage,the paper sets up new flowing model of fracture reservoir in porous that includes fracuture and matrix skin factor Sma. The model analysis transient pressure effect of Sma and results of the model apply data interpretation in oilfield. It is also important for well test interpretation and evaluation of formation damage.更多还原
