Abstract
Introduction. The participation of biocenoses in the formation of various minerals has been studied and proved for quite a long time. But in some cases their role in the formation of sedimentary strata is not obvious. For example, the formation of secondary minerals in bottom-hole parts of wells at underground gas storages remained unstudied for a long time. In a number of wells such minerals had a strong negative influence on filtration-capacity properties of rocks and structural parts of wells.
Aim. In order to optimize well operation and to understand the process of mineral formation by bacterial pathway, newly formed minerals and rock matrix of bottomhole zones of underground gas storage wells were studied.
Materials and methods. To study the mineral and bacterial composition of the rocks we carried out studies on scanning electron microscope, optical microscope, diffractometer, as well as various optical studies.
Results. The groups of newly formed minerals were revealed and their genesis was determined; bacterial biocenoses played the greatest role in the formation of such minerals.
Conclusion. The volume and properties of filtration-capacity space of UGS reservoir rocks are largely determined by a wide complex of geological, biogenic, bio-chemogenic and technological factors.
