| 摘 要： | 通过注水保持油层压力的方法开发非均质油藏,不可避免会造成油井含水或部分油井水淹.注入水窜入油井时,不管低渗透层是否受到开发,大部分注入水进入到高渗透层,因而使低渗透层在开发过程中采油速度很慢,或是基本未投入生产.为了降低产水量,保持或提高采油量,必须对已开发的非均质油藏实施相应的堵水调剖措施,防止注入水沿高渗透带水锥突进到油井,影响水驱采收率.本文建立了应用模糊综合评判方法优选非均质油藏调剖井和层的数学模型,通过实例分析表明,运用综合评判方法优选调剖井和层是一种客观有效的方法,该评价方法计算方便,易于操作和推广.

| Abstract: | It is unavoided to bring about that the oil-well contains moisture or part of the oil-wells be flooded by the means of water injection to keep the oil layer pressure to develop the unhomogeneity oil reserve.While the water flee enter the oil-well,whether the lower permeated layers have been developed or not,most of the water will enter into the higher permeated layer,and then the oil extraction speed of the lower permeated layers will be very slow or not go into operation basically.In order to control water... |
