The article gives a brief review of currently used reagents. Technological advantages of Kometa-Meteor polymer composition of domestic production are shown, expressed in possible economic benefit, which consists in reduction of expenses for intensification of fluid inflow and preparation of drilling mud. A number of problems encountered in sinking and drilling wells are considered, and the advantages of drilling fluids treated with Kometa-Meteor for such conditions compared to other fluids are shown. It concludes with a review of the pricing of existing reagents.
The principles of application of mathematical statistics in the development of compositions of flushing fluids are stated. One example of data processing by Statgraphics program and obtained results are shown.
Relevance of development of flushing fluids is substantiated by the lack of a range of effective and inexpensive import-substituting reagents for the preparation of drilling fluids used in the oil and gas industry in Russia. The analysis and comparison of clayey and biopolymer flushing fluids with fluids produced by treatment with acrylic polymer "Comet-Meteor" are made, with the advantages of the latter indicated. Laboratory researches are carried out, on the basis of which the further direction of works for creation of flushing liquids is offered.
