泡沫驱是一种可同时克服制约原油采收率各种因素的提高采收率技术,可大幅提高水驱后的采收率,成为近年来备受瞩目的提高原油采收率技术。起泡剂的性能的稳定将直接关系到驱油的成效,本文通过实验研究,对所选泡沫剂的发泡效果进行评价,确定出十二烷基苯磺酸钠,十二烷基磺酸钠和R发泡剂具有较强的稳定性和发泡能力,适合作为河南油田在稠油油藏开发时的调剖剂。
Bubble flooding is a technique that can simultaneously enhance oil recovery by limiting various factors that restrict oil recovery. It can greatly enhance oil recovery after water flooding and has become a highly anticipated technique for enhancing oil recovery in recent years. The stability of the performance of the foaming agent will be directly related to the effectiveness of flooding. In this paper, the foaming effect of the selected foaming agent is evaluated through experimental studies to determine the effects of sodium dodecyl benzene sulfonate, dodecyl sulfonic acid Sodium and R foaming agents have strong stability and foaming ability and are suitable as profile control agent for Henan oilfield when developing heavy oil reservoirs.
