调剖措施效果影响因素探析

Analysis on Influencing Factors of Profile Control Measures

随着注水开发持续深入,大部分老区油田已处于中高含水期。如何稳油控水、提高区块采收率是制约老区油田进一步发展的难题。调剖工艺作为水驱油田稳油控水重要的技术手段之一,如何高效运行,保证措施效果是关键。文章以奈曼油田水井化学调剖为例,详细阐述了影响调剖措施效果的影响因素,强调现场实际施工中过程管控的重要性,对区块持续稳产具有现实意义。

With the continuous deepening of water injection development,most old oilfields have been in the middle and high water cut stage.How to stabilize oil,control water and improve block recovery is a difficult problem restricting the further development of old oilfields.Profile control technology is one of the important technical means to stabilize oil and control water in water drive oilfield.How to operate efficiently and ensure the effect of measures is the key.Taking the chemical profile control of water wells in Naiman oilfield as an example,this paper expounds in detail the influencing factors affecting the effect of profile control measures,emphasize the importance of process control in the actual construction on site,which is of practical significance to the sustainable and stable production of the block.
