安塞油田是特低渗油田,而且比较典型,油井堵塞、单井产能低为比较突出的问题,为解决这两方面的问题,砂岩油藏酸化解堵措施每年都要大量进行,但目前评判油井酸化效果时,只能以酸化之后的相关指标为依据,导致评判结果的预测性、前瞻性缺失,而且尚未实施酸化措施时有效性分析无法开展,因此,应对影响酸化的因素做出正确的、全面的认知,经优化,保证分析工作能够在酸化前开展。本文中探讨了安塞油田油井酸化工艺技术的有效性及优化方法。
Ansai Oilfield is a special low-permeability oilfield, and more typical, plugged wells, single well productivity is more prominent problem, in order to solve these two problems, sandstone reservoir acidification and plugging measures every year a lot of judgments, but the current judge When the oil well acidification effect can only be based on the related indicators after acidification, it leads to the predictive and forward-looking defect of the judgment result, and the effectiveness analysis can not be carried out before the acidification measures have been implemented. Therefore, the factors affecting the acidification should be correct , A comprehensive understanding of the optimization, to ensure that the analysis can be carried out before the acidification. In this paper, the effectiveness and optimization methods of oil well acidification technology in Ansai Oilfield are discussed.
