摘要
采油三厂多层系开发区块主要在D1、D2、D3、D4等C1油藏,多层系开发油井共计1 126口,平均单井日产油2.05 t。笼统暂堵酸化对于多层开发油井针对性较差,措施后增油效果不明显,2014-2016年开展笼统暂堵酸化措施89井次,平均单井日增油0.73 t,不能达到解堵目的。另外笼统暂堵酸化是采用固体聚丙烯酰胺,施工时容易卡钻,因此,急需开展分层暂堵酸化工艺技术研究,解决多层开发油藏的层间矛盾,提高技术针对性。
The development of the multi-layer system of the oil production plant is mainly in the reservoirs of D1、D2、D3、D4 and so on. There are 1 126 wells in the multi-layer system,and the average single-well daily oil is 2.05 t. In addition, the effect of oilification is not obvious for the multi-layer development of oil wells, and the effect of increasing oil is not obvious. From 2014 to 2016, it is carried out. The average single-daily well oil is 0.73 t.In addition, the temporary cure acidification is the use of solid polyacrylamide, easy to drill when the construction, therefore, the urgent need to carry out hierarchical temporary plug acidification technology research to solve the multi-layer development of the inter-layer contradiction, improve the technical relevance.
