APPLICATION OF SELF– DIVERTING CHEMICAL COMPOSITIONS TO IMPROVE THE EFFICIENCY OF ACID TREATMENTS OF FRACTURED POROUS CARBONATE RESERVOIRS

 

Annotation. Currently, due to the insufficiently complete development of reserves from low-permeable intervals of heterogeneous carbonate reservoirs, the constantly growing waterlogging of wells, and at the same time with the inevitable increase in the multiplicity of treatments of bottomhole zones (OPZ), there is a need to increase their efficiency. The article presents an analysis of the results of the application of acid treatments in the fields of Udmurtia, a comparative assessment of the effectiveness of the applied directed acid treatments, including with an increase in the multiplicity of treatments used in the field. The article also discusses the use of self-bending acid compositions to increase the effectiveness of hydrochloric acid treatments.

Keywords: treatment of the bottom-hole zone, acid treatment, carbonate rock, heterogeneity, directed acid treatments, deflectors, efficiency.
