| description | Relevance. Oil deposits often have a complex heterogeneous structure with hard-to-recover reserves, the development of which is complicated by the fact that different layers have different permeability. As a result, the use of flooding, the most common method of increasing oil recovery, quickly becomes ineffective as water begins to circulate through washed, highly permeable channels. The solution to this problem is the use of blocking agents, special compositions that close these channels and force water to displace oil from previously unused zones. The main aim of the research is the analysis of the effectiveness of compositions based on urea and urotropin as blocking agents in enhanced oil recovery process. Research methods: simulation of oil displacement process on SAP-700 setup with two parallel columns; gas method for determining permeability of the rock. Results. The effectiveness of the use of compositions based on urea and urotropin as blocking agents in order to increase recovery factor was experimentally confirmed in laboratory conditions. The first experiment showed that ultimate oil recovery factor was 0,4, 0,16 of which was additional The second experiment showed, that ultimate recovery factor was 0,38, 0,24 of which was additional. These technologies for oilfields with different reservoir permeability can significantly increase the degree of reserve development compared to conventional flooding. |
