摘要： 以老区高含水油田为目标,开展生物聚合物调剖技术研究。在生物聚合物特性研究的基础上,探讨了岩心注入能力和封堵调剖能力。在取得室内物模驱油试验提高采收率9%,油井堵水增油647t后,对2口水井进行了生物聚合物调剖矿场试验,周围油井含水率下降7.7%～64.5%,一年来持续有效。通过矿场试验的跟踪监测和动态分析,明确了影响生物聚合物调剖效果的主要环节及因素,为该项技术的深入研究和大规模推广应用指明了方向。

Abstract: In the light of high water-cut oilfield, technical study of the biopolymer plugging adjustment is made. Based on the biopolymer property, core flooding ability and biopolymer plug adjustment capacity are discussed. Following lab experiment of physical model oil displacement with enhancing recovery of 9% and incremental oil production of 647t by oil-well water block-off, the field tests of biopolymer plugging adjustment in two water producers are made, lowering water-cut of 7.7~64.5% in adjacent oil wells with more than one year effec-tiveness. Through test monitoring and performance analysis, that the main factors influencing the effect of biopolymer plugging adjustment are confirmed, being as a guide for in-depth research and large-scale application of this technique.

Key words: MEOR, biopolymer, plug adjustment, field test
