In this paper we consider the hydrochemical monitoring of field development in terms of reducing the negative impact on the environment. Considered the problems solved by the hydrochemical method. Value ecological and hydrochemical monitoring is to ensure a balanced withdrawal and renewal of natural resources. One of the powerful anthropogenic impacts on ecosystems at various levels is the process of extracting energy from the depths associated directly with the removal of the earth's surface large mass associated solid, gaseous and liquid media. Specific geological features of Astrakhan gas condensate field (salt dome tectonics) , significant depths (over 4000 m), abnormally high reservoir gas pressure (62 MPa) and temperature (over 110 C), high toxicity and aggressiveness of commercial products are the basis of the need for mandatory control technological influence development Astrakhan gas condensate field on the environment. AGKM allocated on two sources of water cut wells - internal and plantar water. Found that the most dangerous for the development processes are plantar water with significant energy potential and infinite, compared with fallow, volume. The Astrakhan gas condensate field to date the impact of bottom water formation energy does not affect the operation. Mode remains gas. However, growth in the number of wells watered out and increase bottom water in the raw materials indicates its immediate deposit.
