低渗透油藏暂堵酸化工艺技术研究及应用

油房庄油田属典型的低渗透油藏，储层非均质性严重，层间渗透率变异系数较大。针对油井酸化措施后，出现在增油的同时油井含水大幅度上升的问题，提出了暂堵酸化工艺技术，通过现场试验及应用，取得了较好的控水增油效果，丰富了低渗透油藏油井酸化工艺技术，对于开发低渗透油田，延长油田低含水采油期，具有重要意义。

Low permeability reservoir plugging Acidification Research and Application

Youfangzhuang oilfield is a typical low-permeability reservoirs, reservoir heterogeneity, a larger interlayer permeability coefficient of variation. Measures for the oil well acidification, increase of oil in water, while a significant rise in wells proposed temporary blocking acidification process technology, the field tests and application of water to achieve a better control effect of increasing oil, rich in low permeability oil possession of oil acidification process technology, the development of low permeability reservoir, to extend the field of low water content oil is significant.
