System solution for technological problems of well construction completion

Extended Abstract: The paper highlights the factors impeding the technology of well cementing in the well construction process, summarizes the indicators and problems of casing cementing job quality. Based on the analysis of thermodynamic processes running in casing cementing, it is shown that poor quality of well cementing is caused by irreversible processes of destruction of initial properties in cementing slurry-stone that characterize traditional technologies of unsystematic nature. An alternative to traditional technologies is technology based on system principles, including a complex of multitechnologies applied in wellbore hydromechanical hardening. The complex excludes occurrence of various compli- 73 http://nanobuild.ru info@nanobuild.ru 2018 • Vol. 10 • no. 1 / 2018 • Том 10 • № 1 SYSTEM SOLUTIONS FOR TECHNOLOGICAL PROBLEMS Machine-readable information on CC-licenses (HTML-code) in metadata of the paper System solution for technological problems of well construction completion by Polyakov V.N., Zeigman Yu.V., Kotenev Yu.A., Mukhametshin V.V., Sultanov Sh.Kh., Chizhov A.P. is licensed under a Creative Commons Attribution 4.0 International License.Based on a work at http://nanobuild.ru/en_EN/nanobuild-1-2018/.Permissions beyond the scope of this license may be available at jvzeigman@ya.ru.

Nanotehnolocations (up to 40 m3/h absorption, gas oil and water manifestations, fountains, emissions, instability and hydraulic fracturing of rocks) in the construction of oil and gas wells in various geological and technical conditions. The paper marks the advantages of the multitechnological complex respect to the traditional methods of wells completion. In the process of well operation, the multitechnological complex prevents occurrence of stuck fluid and cross-flows. Wells introduced from drilling are characterized by higher production rates and lowered, by more than twice, water cut of the extracted produxts, that provides a nonlinear increase of oil recovery factor.
