Abstract


The issues of technology optimization based on detailing the properties of productive deposits are key in achieving high technological efficiency of methods and technologies for influencing productive formations. In this paper, based on filtration experiments on the example of core samples from the Rostashinsky field, the potential for regulating the properties of rocks in the near-wellbore zone is studied when performing technologies for influencing productive formations, taking into account changes in the surface tension of rocks and preventing swelling of the clay material of the rock. Filtration laboratory studies were performed on the VINCI CFS-700 unit for research and development of EOR technologies. The generalized comparative results of the use of various reagents that affect the wettability of the rock and the swelling of the clay material of the rock in order to control the properties of the reservoir make it possible to create initial well conditions for ensuring effective stimulation of production, including the performance of such works as hydraulic fracturing.

Key words:

Filtration experiment, rock mineralogy, clay swelling, inert brine, reservoir wettability control, hydrophilicity and hydrophobicity of rocks, bottomhole zone control, optimization of reservoir stimulation technologies
