安塞油田是典型的“三低”油田。近年来,随着开发时间的延长,油田综合含水逐步上升,部分井已进入中高含水期,如何采取有效措施,提高这部分井的单井产能,是措施增产中的难点。本文通过分析改变相渗压裂效果,总结其应用的范围,为下步中高含水井措施增产工作提供方向。
Ansai Oilfield is a typical “three low ” oil field. In recent years, as the development time prolongs, the comprehensive water cut in oilfields gradually increases and some wells have entered the middle and high water cut-off periods. How to take effective measures to increase the single well productivity in this part of wells is a difficult point in increasing output. In this paper, we analyze the effect of the phase-infiltration and fracturing, summarize the scope of its application, and provide the direction for the next step in high-yield wells measures to increase production.
