对于多层状和大厚层油气藏的酸化，由于储层纵向上的非均质性或污染程度的差异，必须考虑酸液的分流。采用笼统酸化显然不易达到改善出油气剖面或吸液剖面的目的；采用分层酸化则费时、费力，且往往难以奏效。文中介绍的暂堵酸化技术可以有效地解决大厚层纵向非均匀堵塞和多层油藏各层不同堵塞程度的酸化解堵问题，对于恢复和改善油气井纵向出油气剖面或水井纵向吸液剖面具有其独特的作用。给出了该技术的原理、完整的数学模拟计算方法、优化施工参数以及现场操作实施方案；并且研制了暂堵酸化设计软件；研制并开发出了分别用于油、气、水井的新型暂堵剂。该工艺有效、简单易行，可以在现场迅速投入运用；已取得了良好的经济效益，文中给出了现场应用实例。
For the acidification of multi-layered and large-thick reservoirs, the splitting of the acid must be considered due to differences in vertical reservoir heterogeneity or contamination. Obviously, it is obviously difficult to achieve the purpose of improving oil profile or suction profile with general acidification. It is time-consuming, labor-intensive and often difficult to work with by layered acidification. The temporary plugging acidification technology introduced in this paper can effectively solve the problem of longitudinal plugging and non-uniform blockage of large thick layers and different plugging of different layers in multi-layer reservoirs. It is of great significance for recovering and improving the longitudinal profile of oil and gas wells, Has its unique role. The principle of the technology, the complete calculation method of mathematical simulation, the optimization of construction parameters and the implementation of the site operation are given. The temporary plug acidification design software is also developed. A new type of temporary plug for oil, gas and water wells is developed and developed Agent. The process is effective, simple and easy, and can be put into operation quickly in the field. Good economic benefits have been achieved. The field application examples are given in this paper.
