重点介绍法国石油研究院的堵水技术 (IFP堵水技术 ) ,开发的堵水剂都是相对渗透率改善剂 (RelativePermeabilityModifiers,又称Disproportionate Permea bilityReducer) ,对油或气体的相对渗透率影响并不大。IFP化学溶液满足笼统注入的条件。阐述了IFP堵水技术的特性 ,分析了IFP选井方法和堵水工艺技术 ;还介绍了用IFP技术堵水的典型现场试验 ,包括地下储气库的储气井、开采稠油的水平井、海上的砾石充填井、多层水驱井等。此外也介绍了IFP的最新技术发展的两个主要研究方向 :①针对注水井处理 ,IFP进行了微凝胶深部调剖剂的研究 ;重点是研究对微凝胶的大小及构造的控制。②针对改善笼统注入效果 ,进行了预处理转向剂的研究 ;该转向剂以高分子聚合物的无稳态滞留现象 (称为“桥联吸附”)为基础
It focuses on the technique of plugging at the French Petroleum Institute (IFP plugging technology). The developed plugging agents are Relative Permeability Modifiers (also known as Disproportionate Permea bility Reducers) and do not affect the relative permeability of oil or gas Big. IFP chemical solution to meet the general conditions of injection. The characteristics of IFP water blocking technology are expounded, the IFP well selection method and water blocking technology are analyzed, and the typical field tests of water plugging with IFP technology are also introduced. These include gas storage wells in underground gas storage reservoirs, horizontal wells for heavy oil production, Sea gravel filling wells, multi-layer water-driven wells. In addition, two main research directions of the latest technological development of IFP are also introduced: (1) For injection well processing, IFP has carried out the research on the micro-gel deep profile control agent; the emphasis is on the control of the size and structure of the microgel. (2) In order to improve the general injection effect, the pretreatment of diverting agent was studied. The diverting agent is based on the phenomenon of non-steady-state retention of macromolecule polymer (called “bridging adsorption”)
