摘要
蒸汽吞吐是目前开采砂砾岩稠油的主要方法,频繁的吞吐过程会对储层造成伤害,但是综合应用防缩膨技术来解除储层伤害的较少。利用储层敏感性评价实验确定储层伤害类型,继而筛选适宜浓度的防缩膨剂,通过室内实验综合评价与地层水的配物性、耐酸碱性、热稳定性、防缩膨周期、处理半径、对驱油效率的影响、注入方式及注入程序,并制定了适应于研究区的现场施工工艺技术。研究结果表明,综合应用耐高温、耐水洗的防缩膨剂,不仅能够从根本上消除黏土分散、膨胀及运移造成的伤害,而且能够提高吞吐效果,最大程度地增加经济效益,并对砂砾岩稠油油藏的经济有效开发具有一定的指导意义。
Steam stimulation is the main method of production of viscous,but frequent stimulation process will be harmful to reservoir,yet the comprehensive application of anti-swelling and shrinking technology to remove the reservoir damage is little.Reservoir sensitivity evaluation experiments are used to determine the type of reservoir damage.Through the indoor experiment and comprehensive evaluation of the distribution of formation water,acid and alkali resistance,thermal stability,the anti-swelling cycle,processing radius and impact on oil displacement efficiency,injection way and injection procedure,the field construction technology adapted to the reservoir is established.The results show that the comprehensive application of the anti-shrinking and swelling agent,not only can eliminate the damage because of the clays dispersion,expansion and migration.but also can improve the throughput effects,maximize economic benefits,and it's beneficial to the similar glutenite heavy oil reservoirs.
