It is proposed to introduce a new stage of rock transformation under technogenetic impact on it, in order to increase the efficiency of production operations - technomorphism, which cannot be identified with natural processes (lithogenesis). Technomorphism is the process of transforming rocks in reservoir conditions under a certain technogenetic impact. The purpose of studying the processes of technomorphism is to increase the efficiency of production by predicting changes in rock properties under a certain technogenetic impact on it. The study of technomorphism is considered on the example of thermal impact on oil source Upper Jurassic rocks of Western Siberia. During the air injection into the Upper Jurassic rocks, oil self-ignites and its oxidation is carried out with heat generation and temperature increasing in permeable reservoir layers. As a result, in reservoir rocks characterized by an increased content of organic matter (up to 5%), it is oxidized and the rocks acquire hydrophilic properties. During the oxygen and water injection, gypsum or anhydrite forms and seals the open porosity of the rocks. In this case, further oxygen injection becomes impossible. The scheme of changes in organic matter, minerals and the reservoir space of the rocks of the Upper Jurassic deposits depending on the temperature is proposed. The study of the technomorphism of rocks under various technogenetic impacts contributes to the understanding of changes in the mineral-component composition of rocks, porosity, various properties of rocks, which makes it possible to correct solutions aimed at developing technologies for increasing oil recovery, in particular, and production in general. The author supposes that studies of technomorphism are becoming more and more relevant due to the practical aims of human production activity.
