FIELD TESTS AND RESULT ANALYSES OF WATER CONTROL TECHNIQUE USING EPOXY RESIN SMALL BALLS

This paper introduces technology parameters,injection equipment and technology process of plugging water technique with epoxy resin small balls,provides a formula to estimate the water plugging agent consumption,analyses existing problems,and then proposes improvements.In field tests of 5 wells in Daqing oilfield,this technique obtains good results of water decrement of 215 cubic meters and oil increment of 3.5 tons per day.This shows that the said agent has reached the technical and economic indexes such as small plugging radius,high plugging strength,small agent volume,low cost,simple technology and safe operation and so on.
