The construction of oil and gas wells is considered to be one of the most complex mining and geological and engineering constructions, the most important of which is the discovery of productive horizons as a priority. Until recently, the discovery of a productive facility was technologically small compared to the dismantling of overgrown breeds, and on the basis of the development of technological programs were left technical and economic issues without complications and as much as possible. During this period you can get good results from the permeability of the hydrocarbon layer.

Attention was drawn to the possibility of gas manifestations, in connection with which preventive measures were taken. Since the exit and entry of drilling fluid is the main factor in these processes. Especially where pressure is abnormally low than reservoir.

The efficiency of the development of oil and gas wells is largely determined by the state of the bottomhole zone during the completion period, i.e. well casing. As a result of mining and geological, physicochemical and mechanical impacts when casing wells, the reservoir properties of rocks in the bottomhole zone, especially the production intervals, change.

The physicochemical effect on the bottomhole zone is due to the interaction of the formation fluid and the filtrate of drilling and cement mud, as well as the action of adsorption, capillary and diffusion-osmotic forces.
