Abstract
The complex of oil-based technological fluids is developed in ООО LUKOIL-Engineering in order to work with the productive formation presented water sensitive terrigenous rocks: invert-emulsion drilling fluid and waterless acid-micellar breaker are presented. The evaluation method of invert-emulsion filter cake destruction by breaking compositions is considered. Requirements to breaking compositions depending on the nature of the pollution zone are formulated. Methodological approaches to evaluating the impact of fluids on the reservoir properties are presented. This technological fluids complex has been used successfully in the fields of Perm region, the results of well hydrodynamic research methods have proved technical and economic efficiency for an integrated approach.
