Numerous experimental and field studies have established that during the development of oil and gas fields, there are deformations of rocks that occur due to changes in reservoir pressure. It is established that with a drop in reservoir pressure, the volume of the pore space of the formation decreases due to the elastic expansion of the rock grains and an increase in compressive forces transmitted to the skeleton from the masses of the overlying rocks. As a result, there is a change in the deformation processes in the porous medium, accompanied by a decrease in its porosity and permeability, and a more significant change, compared with the porosity of the formation, is the permeability under one and the same pressure change. The manifestation of these anomalies in reservoir conditions, which cause nonlinear effects, can significantly affect the entire process of reservoir development and lead to various qualitative and quantitative discrepancies between the observed facts and the indicators that were calculated.
Currently, the National gas supply operator in Kazakhstan pays special attention to the rational use of natural gas for its own and technological needs, while maintaining the optimal management of the gas transportation system, taking into account the specific technical situation of the equipment. Energy efficient management of gas pipelines is one of the priority directions for optimizing gas costs. The use of innovative methods of energy-saving technologies during the operation of the gas transmission system, an increase in the efficiency of gas-pumping units, as well as the implementation of automated energy saving control systems, will significantly increase the efficiency of gas transportation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
