| 摘 要： | 针对在油田注采过程中 ,经常由于忽略注采速度的影响而导致地层发生微粒运移 ,从而堵塞地层孔隙 ,使油气井产量急剧降低 .尤其对于低渗油层 ,地层伤害程度更大 .在岩心速敏实验基础上 ,应用渗流力学和采油工艺等基本原理 ,将室内临界流速与油田开发相结合 ,建立了微粒运移堵塞预测数学模型 ,并利用该模型对大庆龙虎泡油田几口油井进行预测 .预测结果表明 :金 1 91、金393井存在一定程度的微粒运移损害 ,与现场实际情况基本吻合 ,从而证实该技术切实可行 |

| Abstract: | When the rate of oil production or water flooding is greater than its critical value, the migration of formation solid particles takes place. This leads to formation pore plugged and the output of oil and gas wells falling. This formation damage is more serious to low permeability reservoir than high permeability reservoir. Based on the velocity sensitivity experiments of cores, the macroscopic quantitative prediction model of the particle migration was established. The predicted results of 3 wells in Longhupao oilfield are basically identical with real conditions, which shows the prediction model is practical. |
| Keywords: | Longhupao oilfield critical flow rate migration of particle mathematical model formation damage critical output |
