Abstract

A new effective composite “Emir” has been created, which reduces the swelling of clay minerals and cleans the near-well zone of oil and gas-saturated layers from residues of drilling fluid, technical and formational water, resin-asphaltene components and paraffin; thereby restoring the efficiency of the well. The composite has high cleaning characteristics and the ability to foam in the presence of highly mineralized waters (up to 250 g/l), oil products and mineral acids. It also forms both straight and reverse mobile water-oil emulsions, which is important for cleaning oil layers. Based on the results of testing the “Emir” composite in production conditions on gas and oil wells, it was concluded that the use of the “Emir” allows increasing the discharge of hydrocarbon fluids from 20 to 50 % or more. “Emir” composite can also be used on “low-flow” wells clogged or eliminated for geological and technical reasons; this makes it possible to significantly increase recoverable reserves of hydrocarbons in various oil and gas-bearing regions, especially taking into account the small volumes of drilling and the low success rate of searching for new oil and gas fields.
