In article geological and geocryologic conditions in the territory of the Harampursky oil-gas condensate field are considered. The cryologic features of permafrost breeds of the central region Pur-Tazovsky of Entre Rios near the Harampursky oil-gas condensate field received as a result of laboratory researches of physical and mechanical properties of soil are given in article. Engineering-geological elements are singled out and normative values of soil characteristics are obtained on the basis of statistical processing of the results of physical and mechanical characteristics of the soils of the Kharampur field (Northern deposit) according to GOST 20522-2012. The key parameters of mechanical properties of soil defining the bearing ability of the bases and their deformations - strength and deformation characteristics of soil are received (the angle of internal friction, specific coupling c, the module of deformation of E and coefficient of cross deformation ОЅ soil). The relevance is caused by the fact that, are in development a northern and southern part of the Harampursky field now.
