During middle and later stages of waterflooding, the water flows along high permeability formations ineffectively, a great quality of oil remains in low permeability formations. The polymer flooding is an ideal EOR method, but needs to select reasonable injecting polymer pressure gradient(threshold pressure gradient) which makes polymer solution slug advance even in heterogeneity formation, then impr...             一般油藏都有不同程度的层间非均质性。在注水开发中、后期，水沿着高渗透油层无效流动，而使低渗透油层留下大量原油。聚合物驱是较理想的提高采收率方法，但需选择合理的注聚压力梯度（阈压梯度）才能使聚合物溶液段塞在非均质油层中较均匀推进，从而更有效地改善油层吸水剖面和提高原油采收率。在所给实验条件下，注聚阈压梯度值为０．２ＭＰａ／ｍ，以此值向实验岩心注入聚合物，与水驱相比，吸水剖面改善率可达７１．７２％，提高采收率１３．８１％，该文还首次提出了阻力比、残阻比的概念。 文摘来源          The design and application of polymer flooding used in the past is “unitized slug in each stage”. It means that all injected well are the same polymer solution slug in the same stage and different stage with different slug. This manner didnt consider the different formation parameters in different well, consequently resulted in polymer channeling in some wells with low viscosity and blocking in some other wells with high viscosity. In view of the problem appe...             原有聚合物驱的设计和实施采用“分阶段、统一段塞”的注入方式，即同一阶段内，注聚区的所有注入井注相同浓度的聚合物溶液段塞，不同阶段，聚合物溶液的浓度不同。这种方式没有区别各井区不同的地层参数，使有的井因粘度太低而仍存在聚合物窜流，而有的井则因粘度太高注不进去。根据孤东油田七区西Ｎｇ５２＋３层和八区Ｎｇ３～６层的聚合物驱工业性矿场试验中暴露出的问题，提出并实施了“一井一制”聚合物注入段塞，井与井之间、同一井的不同时段，其注入段塞也不同。为了实现这一点，根据流动系数、单井注入压力、吸水指数、启动压力、大孔道分布等５个条件，设计了５种段塞，在不同井、不同时段注入。１９９６年８月起在七区西的３７口井上实施，２６口井见效，到１９９７年７月，比原聚合物驱又增油２０１９０ｔ；在八区推广实施３个月，也取得明显增油效果。 文摘来源          A new enhanced oil recovery technique is put forward. The timing of polymer solution injection, polymer slug and molecular weight on the oil displacement efficiency are studied by core floods. The results indicate that the higher the polymer concentration is, the better the recovery result is, the less the treatment of the product fluid is. It is also shown that oil recovery increased with polymer solution slug before a given value, and inclined to level after...             在室内两维纵向非均质岩心上,研究了高质量浓度聚合物驱注入时机、聚合物相对分子质量、聚合物段塞体积及段塞组合对驱油效果的影响。结果表明:聚合物质量浓度越高,采收率越大,产出液处理量越小,经济效益越大;越早转注高质量浓度聚合物驱采收率越大;随着聚合物段塞体积的增大,聚合物驱采收率增加,但聚合物段塞体积增大到一定值后,采收率增加的速率开始变缓;聚合物相对分子质量越高,驱油效果越好;在聚合物总用量不变的条件下,阶梯段塞驱油效果略优于整体段塞。 文摘来源       相关查询: polymer solution aqueous polymer solution linked polymer solution polymer solution preparation polymer solution model water polymer solution polymer solution property polymer 　 solution polymer aqueous solution polymer solution viscosity gradient polymer solution concentrated polymer solution  对查询结果不满意
