Application of Temporary Plugging-Acidulation Technology in Low Permeability and Inhomogeneous Reservoirs

Abstract:

For low permeability and inhomogeneous reservoirs, defective effects such as water content increasing are usually resulted from traditional acidization. The principle of temporary plugging - acidization in Low permeability and inhomogeneous reservoirs, well selection and treatment requirements are introduced in this article. The temporary plugging agent selected from laboratory was used for field experiment. Result shows that: for wells of multiplayer and thin interlayer, temporary plugging – acidization technique can acidify the formation by the subsequence from high to low permeability, thus significantly increase the effectiveness of acidization, decrease the requirement of treatment operation and save the cost of production; the price of selected temporary plugging agent is comparative low, and the field process can be easily realized without affecting the progress of traditional acidization which has a good practicability and value to extend and apply.
