The paper examines the factors that determine the nature of the decline in boreholes at the opening of halogen salts of great thickness. Raises issues related to the valuation of drilling mud during drilling in the beds of precipitation. The article contains the thermodynamic expression of the secondary crystallization process; salt in the borehole wall affects the choice problem requirements modifier medium mud to prevent secondary crystallization. The results can be used to solve the problem of preventing the narrowing of the wellbore due to secondary crystallization of salt on the walls.

In the article is considered a procedure for creation of a digital geological and geophysical model of the Pre -Ural fore-deep and the area of fore folds of the Ural (within the limits of the Orenburg region). The model includes data of drilling, regional and prospecting CDP method, gravimetry and aeromagnetic measurements, and also a cumulative cosmic still photograph with interpretation results. Local aspects of the model in prospecting operations for oil and gas are marked.

This paper examines the nature of the restriction borehole at the opening of thick salt. Raises issues related to complications during drilling in thick beds of precipitation. The article contains a physical-chemical basis of the process of secondary crystallization of salt on the walls of the well, the problem involves the prevention of secondary crystallization by modifying the environment mud. The results can be used to solve the problem of preventing the narrowing of the wellbore due salts crystallization on the walls of the well.
