Engineering-geological features of rocks play an important role in the construction of any facilities, and particularly in the oil and gas industries. This is because in the construction of wells disturbed natural geodynamic equilibrium; therefore, there are various geological complications such as: landslides, avalanches, outdoor fountains, columns collapse, narrowing of the borehole, cavernosometry and zheloboobraznogo, clamps drilling tools and etc. All of these complications are due to the physical and strength properties of rocks that you need to know when designing wells and field development. In addition, if exploration and development of oil and gas fields in the selection process fluids, pumping of industrial waste water, pumping of water or other agent, falling reservoir pressure and temperature changes in the rock mass, changing the physical properties and triggers various chemical processes causing the appearance of precipitation with other properties. Therefore, the study of rocks from the point of view of engineering Geology is very important and the topic is relevant.
