摘　　要：本文针对油井酸化处理后,出现了在增油的同时油井含水大幅度上升的问题。通过分析其主要原因是酸化只对高渗带的油层物性得到改善,而油层的低渗带的物性得不到相应的改善。根据这一情况,建立了暂堵酸化工艺技术,研制了ZDJ-1暂堵剂,通过现场试验及应用,取得了较好的控水增油效果。丰富了低渗透油田油井酸化工艺技术,对于开发低渗透油田,延长油田低含水采油期,具有极为重要的现实意义。this thesis mainly an Experimental study method of temporary plugging acidization and give an experimental analysis of the oil solubility, particle destribution of the tempo - rary plugging agent, and its stability in acid fluid and the compatibility of temporary plugging agent with acid fluid. Using a specially designed temporary plugging acidizing ex - pefimental apparatus, the paper respectively studies the temporary plugging efficienccy of the temporary plugging agent, the unplugging efficiency in produced fluid, and the temporary plugging diverting efficiency of the cores of different permeabilities. In this paper, we model the acid injection sequence of the actual acidizing process, and make a temporary plugging acidizing experiment. The results show that ZDJ - 1 temporary plugging agent displays excellent oil solubility, inertia in acid fluid, and good compatibility with acid and additives.
