摘要

A scientific research results represented in this paper show significant improvement of the applied nanotechnologies in the area of oil and gas fields development. Deep experimental research has been done in the period 2017-2018 with the goal to create the most environmental and efficient blocking-agent for loss-circulation control and well-killing operation with a minimum negative impact on the natural reservoir system, downhole equipment and surface systems for collecting of oil and gas. The carried out experimental work mainly based on the coreflooding tests which are showed a high-efficiency of the application of nanoparticles with the modified surface for generation of an emulsion-suspension system with incredibly high surface activity and stability properties which can be easily regulated by change the ratio of phases of the emulsion-suspension system [1–7]. The coreflooding tests proved the possibility of the developed emulsion-suspension systems to reach the ultimate blocking effect even in the super-permeable hydraulic fractures with the permeability and conductivity more than 400 Darcy. Four specially developed modifications (samples) of the emulsion-suspension systems with different structure and content of solids have been invented and tested. The results are showed that the blocking effect can be regulated in a wide range of the geological and physical parameters of the petroleum reservoir by change the ratio and type of solids and liquids in the system. The application of the emulsion-suspension systems provides minimal decrease of the hydraulic fracture conductivity-67 times and the maximum-7833 times. The synergetic effect of the compositions of solids with different surface charge provides an opportunity to reach reversibility of the blocking effect into the petroleum reservoir system. The reversibility of the blocking effect assures recovery of the rock productivity for hydrocarbon phase. The surface charge of solids makes a positive impact on the wettability of the rock surface. Also, in the paper disclosed laboratory equipment and methodology of the coreflooding tests carried out on the models of hydraulic fractures.
