摘　　要：注水井暂堵酸化是改善注水井剖面吸水状况的一项重要工艺技术,主要治理非均质油藏单层不吸水或吸水较差的情况,是老油田稳产增产的主要措施手段。但一直以来,缺乏有效的、准确的分析调剖效果评价体系,不仅能直接反应施工的成功与否,为下一步措施提供必要依据,同时能反馈到前期方案设计中,使科研人员能更进一步了解地质情况、堵剂的适用性,以及各种设计参数的合理性。本文从施工压力、注水压力、测调试数据、产液、吸水剖面等多方面多种手段,对暂堵酸化效果进行分析说明,目的通过多个方面,多个角度的结合能够准确分析评价效果。It is an important process to improve the water absorption of injection wells.It is the main measures to improve the yield and yield of the old oilfield by controlling the nonwater absorption or poor water absorption of the non-homogeneous reservoir.However,the lack of effective and accurate analysis of profile control effect evaluation system,not only can directly respond to the success of the construction,the next step to provide the necessary basis for the same time,can be fed back to the early design,so that researchers can go further understand the geological conditions,the applicability of plugging agents,and the rationality of various design parameters.In this paper,the effects of temporary pressure on acidification are analyzed from the aspects of construction pressure,water injection pressure,test data,liquid production and water absorption profile.The purpose of this paper is to analyze and evaluate the effect through the combination of multiple aspects and multiple angles.
