ABSTRACT

The article presents an analysis of the efficiency of production well killing processes in an oil and gas condensate fields of the Volga-Ural province for 2017-2018. In order to prevent fluid loss and gas breakthrough during well service, a specific selection of compositions and technologies is required, based on the field data analysis and laboratory tests. The results of laboratory studies on the development of an invert-emulsion composition with a multi-fractional microcalcite, which can prevent the absorption of the well killing fluid with a fractured reservoir and increased repression, are presented. The technology of well killing is presented using the developed composition in the conditions of producing an oil and gas condensate fields of the Volga-Ural province.
