摘要

塔河油田缝洞型油藏底水能量强，高角度裂缝发育，前期一直采取笼统酸压整体开发的方式，油井水淹后挖潜余地小。通过对致密段的识别及划分，借用砂岩油藏水驱曲线进行油藏剩余潜力评价，充分利用致密段隔挡作用，在现场成功开展了下返酸压实践，获得了很好的增油效果。

Abstract

In the Tahe Oil Field, vuggy reservoirs with active bottom water and well-developed high-angle fractures are explored by means of overall acidification. There is little potential after flooding. Through the identification and classification of dense segment, the remaining potential of reservoir is evaluated by means of the water drive curve of sandstone reservoir. Taking use of the barrier effect of dense segment, return acidification practice is carried out successfully in the field, and succeeds in increasing oil production.
