... hydrocarbons on the Udmurtiya fields, which is characterized by abnormal geological conditions, high-viscosity and paraffin-base oil, caused the low efficiency of traditional methods of bottom-hole formation zone treatment. The using of hydrochloric acid treatments usually causes a number of well problems that leads to the production rate decrease. We suggest using improved acidic compositions, containing multifunctional reagents-modifiers in the article. The acid compositions were tested for compatibility ...

... диапазоне температур. Increasing the efficiency of oil and gas production wells is the primary problem in the industry. It became more actual because the most of the biggest fields are in the last stage development today. Hydrochloric and acid treatment is very common method of chemical treatment on bottomhole formation zone to increasing the oil and gas production in carbonate basin. But those treatments are not successful in spite of long-term applying and researchers aimed to improving ...
