为了探索适合于大庆油田油井压裂增产效果的预测方法,对萨南地区历年压裂资料进行统计分析表明,增产油量与压裂层段内形成裂缝部位的地层系数成线性正比关系,与油井含水成线性反比关系,与油井总压差和生产压差成斜率为0的直线关系。采用萨南地区36口井实际资料,将以上关系进行线性回归,可得各类型油层压裂增产的预测公式,经现场21口井预测检验,符合率超过80%。 In order to explore the prediction method suitable for the oil well fracturing stimulation in Daqing Oilfield, statistical analysis of the fracturing data in the past years in the southern Saigon shows that the oil production increases linearly with the formation factor of fractured fractures in the fractured layer, Water linearly inversely proportional relationship with the total well pressure and production pressure gradient into a straight line 0 relationship. Based on the actual data of 36 wells in the southern Saanen region, linear regression is carried out on the above relations to obtain the prediction formula of fracturing stimulation for all types of oil reservoirs. The prediction of 21 wells in the field shows that the coincidence rate exceeds 80%.
