新型复合调堵剂在不同储层调堵技术研究

摘要
随着注水开发时间的延长,油井产油下降,含水增加已成为非常普遍的问题之一,调剖堵水是国内高含水期、特高含水期开发后油田保持稳产的重要的措施,当油田进入高含水期时,适时地进行多轮次调剖堵水作业及进行各轮次调剖堵水措施间的接替,能取得控水稳油、充分发挥生产潜力的效果。
改性淀粉作为一种强堵剂,具有出色的封堵性能和注入性能,本文对比研究了改性淀粉凝胶及聚合物凝胶的物理化学性质,在模拟大庆采油十厂地质情况的基础上,评价了多轮次调剖作业中堵剂注入方式,注入时机、注入用量以及组合方式。本文对比了改性淀粉调剖剂与聚合物凝胶调剖剂的静态成胶性能和封堵性能;深入了解了多轮次调剖作业中,调剖剂的注入时间对多轮次调剖效果的影响;研究了多轮次调剖中,调剖剂的用量对多轮次调剖效果的影响。分析了多轮次调剖中,调剖剂的类型组合对多轮次调剖效果的影响,结果发现组成由强到弱分布的多轮次调剖体系,可以有效抑制多轮次调剖效果递减的现象。
结果表明,改性淀粉调剖剂具有较好的注入性能和封堵效果;聚合物凝胶具有较好的可移动调驱效果;各轮次越早注入下个轮次调剖剂越好;逐轮次增加调剖剂的用量0.2PV,总体调剖效果较好。
As the extension of the water flooding time, the production of the oil well has been declined,the profile control in the high water-cut stage has become an important measures in our country we can obtain the water control stability and the production potential effect after the multi-round profile control has been applied in high water-cut stage
As a strong plugging agent the modified starch has an excellent pour performance and sealing performance. The chemical and physical properties of the modified gel and polymer gel have been studied in this paper. and evaluated the injection-way injection-timing,volume and combinations.
study on the static gelling properties and blocked performance of the modified starch and polymer gel The results show that compare to the polymer gel,the modified starch agent has good pour performance and sealing effect;study on the injection-timing of the profile gel,the result shows that the earlier profile control injection the effect is better;study on the volume of the profile gel the result shows that the profile effect will be better when increased the volume in every profile round;study on the influence of the different profile combination in multi-round profile control,we found that composition from strong to the weak distribution of many rounds up of profile control system,can effectively restrain the diminishing phenomenon in multi-round profile control.
