Аннотация

Subjects of the research: modified polymer reagent ACD-1, drilling agents, and oil wells. Aim of the research: is in development of technology of production of water dissolvable polymer on the basis of wet waste of fiber “Nitron” by mechanical and chemical methods, new compositions on the basis of this polymer and chemically active systems for the purposes of their application in drilling agents, research of the behavior of their interaction with mud and chemical geological material as well as development of the formulas of drilling agents with inhibiting properties and industrial experiments when drilling of the well in terrigenous and chemical deposits on this basis. Methods of the research: viscosimctry, infrared spectroscopy, elemental and functional analysis and other physical and chemical methods. The results achieved and their novelty: is in the fact that in this research for the first time the conditions of obtaining new water dissolvable polymer has been developed on the basis of the waste of the production “Nitron” by mechanical and chemical methods; also on its basis we have obtained polymer compositions for new makeup of drilling agents with the application of various easily accessible chemical reagents. Technological properties of these agents have been studied, depending on the geological and technical conditions of drilling areas. The methodology of preparing stabilized drilling agents with the application of mineralized reservoir waters has been developed. Practical value: of the thesis is in the development of the technology of obtaining a new water dissolvable polymer on the basis of the waste of the production “Nitron” as well as the application of the results of development in the industrial circumstances, which will provide significant increase of resistance of the well’s walls in potentially unstable mud deposits in the oil and gas areas of Uzbekistan. Degree of embed and economic efficiency: the results of the development have been tried while drilling the wells on the areas Nur-1, Kumchuk-3 and Ustyurt. They have shown high efficiency of the offered drilling agents. Experimental industrial sets of polymer compositions as well as other compositional additions, which meet the requirements of normative technological documentation, have been issued. Technological procedural regulations of the production and technical conditions of the water solvable polymer have been developed. Sphere of usage: Oil and gas industry.
