【摘要】 本文主要进行了交联聚合物冻胶类调剖剂性能评价方法、冻胶类调剖剂适用条件和调剖剂交联反应数学模型三方面研究。 通过查阅大量文献，集中了国内外较为普遍的关于调剖剂的性能评价方法，这些评价方法主要是从调剖剂溶解过程、成胶过程和多孔介质注入过程三个方面展开。这三个方面包括了调剖剂室内实验性能评价的所有指标，简要叙述了实验设备、实验步骤、使用单位和适用范围等相关情况。根据所调研的性能评价方法，选用具有代表性的铬冻胶调剖剂进行室内实验，测定了调剖剂的性能指标参数，研究多种因素的变化对调剖剂性能的影响，得到了较为合理的调剖剂配方以及此类调剖剂的适用条件。给出了凝胶划分原则；围绕着油藏条件和工艺条件，研究了冻胶类调剖剂所适用的条件和范围。第四章用数学方法描述了交联反应涉及的物理化学现象，建立了关于调剖剂在地层条件下运移、交联的数学模型，这是一个关于油、调剖剂水溶液(聚合物、交联剂、凝胶包含在水相中)的两维两相多组分渗流方程，最后给出了差分方程。更多还原

【Abstract】 My paper can be divided into three parts, which study behavior evaluation methods of cross-linked polymer gelants, suitable conditions for gels, a mathematical model simulating gels cross-linking reaction in situ.Those parts include four chapters, in Chapter 1, large pieces of articles were read, many behavior evaluation methods of gels were gathered, which discuss processes of gelants dissolution, gel-forming, gelants injection into porous media briefly. These methods almost include all of the behavior evaluation indexes of gelants in lab. While presenting these indexes one by one, such details as method processes, experiment facilities, employer departments, suitable conditions are also introduced. Chapter 2, on the basis of those methods, lab experiment was carried out with choosing a typical kind of chromium gelant. Some evaluation index parameters were tested, some effects on gelant behaviors were learnt by varying pH salinity concentration temperature etc, a reasonable gelant formulation and the suitable conditions were both given. Chapter 3, based on former two chapters, the criterion of gels sorting was refered; based on reservoir and technique, some conclusions of suitable conditions and application ranges were given. Chapter 4, described some physical and chemical phenomena by means of math, modeled the cross-linking gelant transport gelation in situ, the gelation model is a two dimensional two phases multicomponent equation, in the end differential equations were followed. Although our calculations are quite preliminary even without solution some interesting conclusions on gel systems also have been reached.更多还原
