【摘要】 国内外文献报道的油井嘴流公式,主要是基于孔隙型碎屑岩油藏油井的生产资料而建立的,而对于特殊类型的缝洞型油藏油井的嘴流公式未见报道。目前我国西部塔里木盆地以塔河油田为代表的缝洞型油藏开发规模不断扩大,现有的油井嘴流产量公式难以适应现场的需要。以塔河油田奥陶系缝洞型碳酸盐岩油藏为例,利用基于量纲分析原理的瑞利法和基于现场资料的多元线性回归方法建立了适用于缝洞型油藏的油井嘴流产量公式。现场应用表明,利用新建立的公式对油井产量计算的相对误差小于10%,能满足油井产量计算与预测的需要。更多还原

【Abstract】 The choke flow formulas of oil wells in literatures were based on production data of the classic reservoirs.The formulas for fracture-cave reservoir were not published.At present,the development of fracture-cave reservoirs in Tahe Oilfield is increased continuously.The existing choke flow formulas can not satisfy the field requirements.Using the fracture-cave reservoir carbonate reservoir in Tahe Oilfield,the choke flow equation was derived based on the principle of dimensional analysis and the multiple statistics regression method.The field applications indicate the relative error of the well production rate calculation is less than 10% using the new developed method which can satisfy the requirement of well production rate calculation and future prediction.更多还原
