阐述在羧酸铬 (III) /丙烯酰胺聚合物(CC/AP)凝胶技术方面获得的丰富经验。此凝胶技术在油田波及控制、提高波及体积系数及水气堵塞处理中广泛应用且相当成功。三醋酸铬通常是与此聚合物凝胶技术一起使用的首选化学交联剂。CC/AP凝胶技术的特性是具有很强的凝胶化学性质 ,并且对于油藏环境及干扰极为敏感。自 1998年 5月起 ,此凝胶技术已应用于世界各地 140 0多例波及控制处理中。介绍了CC/AP波及控制凝胶技术的代表性的现场应用及结果 ,并将讨论 10多年来应用CC/AP凝胶技术方面的经验和教训 :包括波及问题及处理的分类及区别 ,用于凝胶波及控制处理的优质候选井及井网的特性 ,为获得成功候选井及井网必须达到的要求 ,为获得成功必须执行的凝胶处理要素 ,成功应用聚合物凝胶波及处理的地点指南 ,凝胶波及处理的风险及缺陷以及质量控制文献
Clarified the wealth of experience gained with the chromium (III) carboxylate / acrylamide polymer (CC / AP) gel technology. This gel technology has been widely used and quite successful in controlling oil fields, increasing the sweep volume factor and blocking water and gas. Chromium triacetate is often the preferred chemical crosslinking agent for use with this polymer gel technique. CC / AP gel technology is characterized by strong gel chemistry and is extremely sensitive to reservoir conditions and disturbances. Since May 1998, the gel technology has been used in more than 140 0 control cases worldwide. The representative field applications and results of CC / AP control gelation technology are introduced and the experience and lessons learned from more than 10 years of application of CC / AP gel technology will be discussed: including classification and differentiation of spill issues and handling for Gel-swept and well-controlled candidate well and well patterns, the requirements that must be met in order to be successful candidates and patterns, and the gel guideline for successful gel filtration processing , The risks and defects of gel swell and quality control literature
