| 摘 要： | 针对非均质多层油藏在开发过程中层间矛盾突出,而单纯的堵水或酸化作业均不能明显改善层间非均质性的矛盾这一现象,研究提出了选择性堵水和酸化一体化技术。经过室内试验,优选出了适宜于该技术的油溶选择性暂堵剂和耐酸选择性堵水剂体系,并进行了现场应用试验,取得了明显的降水增油效果。

| Abstract: | Deal with the interlayer contradiction in exploiting the non-homogeneous multi-layer reservoirs,simple water-plugging or acidizing treatment could not significantly improve the phenomenon of non-homogeneous inter-layer contradiction.The research brings forward the integration technique of selective water-plugging and acidizing treatment.After indoor testing,we prefer first the system of oil-soluble selective temporary blocking agent and acid-resistance selective water-plugging agent which are suitable for the technology.Meanwhile we conduct on site application testing,gaining obvious effect on water-decrease and oil-increase. |

| Keywords: | integration of selective water -plugging non -homogeneous acidizing selectivetemporary blocking agent |
