| 摘 要： | 冀东油田G104-5区块浅层油藏储层胶结疏松,边底水活跃,随着采液速度的提高,边水沿高渗透带突进,油井含水上升速度快,油藏的复杂性给调剖调驱工艺带来一定难度。针对冀东油田地质和开发情况,通过深入分析、研究,在大量室内物模的基础上筛选研制了一种适合冀东油田浅层油藏调驱的交联聚合物体系并应用到现场,取得了良好的降水增油效果,两年来累计增油4.4×104t,有效地控制了该区块边水推进速度,改善了开发效果,为冀东油田夺油上产提供了技术保障,同时为其它浅层油藏区块提高原油采收率提供技术方法和参考依据。

| Abstract: | The shallow layers of Jidong Oilfield are characterized by loosely-binding rock and active edgewater and bottom-water, With increasing recovery ratio, edge-water rushed into these reservoirs along high-permeability region and led to high water-cut in wells. The complexities of the reservoirs bring some difficulties for the use of EOR techniques. Aimed at the geology and development of Jidong Oilfield and by means of analyses and studies as well as based on a large number of interior physical modeling experiments, a new cross-linking polymer system was selected which was suitable for the use of EOR in the shallow layers of Jidong Oilfield. So far, the production has increased by more than 4. 4 - 104 tons and effectively controlled the edge-water rush rates in the block of G104-5, thus the development effectivty of the block was improved. The study provides a new measure for increasing oil recovery of Jidong Oilfield and it provides references for the shallow layers of the other blocks. |
