【摘要】 为了能准确评价一口丼的地层损害程度和损害半径,指导后续增产措施实践,最终实现油田的高产、稳产,提出了一种利用分解试井表皮系数来预测地层损害深度和措施增产率的方法。利用该原理研制了一个储层损害定量评价软件,给出了软件的运行流程图、运行界面、功能设计注意事项;利用软件对某油田25丼层进行实际储层评价。应用结果表明,该软件使用简单、功能较完善、能很好地评价地层污染,具有推广价值。更多还原

【Abstract】 To accurately evaluate the formation damage degree and the damage radius,which can guide subsequent stimulation practices,and ultimately achieve efficient and stable production of oil and gas wells,a method to predict the formation damage depth and increasing rate by using decomposition well test skin factor is proposed.And then according to this principle,a reservoir damage quantitative evaluation software is developed.The software operation flowchart,running interface and functional design considerations are elaborated.Finally,actually evaluation on the 25well and layer of one oilfield by using this software is made.The application results show that the software is simple to use,better able to evaluate the formation damage,and worth promoting.更多还原
