The theoretical foundations of technology for studying gas showings during well drilling

Рой, М.М.

The ways of improving the elements of the methodical approach to the study of gas manifestations in the process of drilling wells are considered. It is assumed that drilling takes place under conditions of low drawdown on the formation, while the pressure from the side of the drilling fluid on the formation is less than the formation pressure, and the gas inflow is determined by filtration processes in the studied section. Filtration processes are described by classical formulas of underground hydrodynamics. The main causes of gas manifestations arising in the process of drilling wells are considered. The necessity of their study in order to obtain valuable geological information is indicated. An alternative approach to ways to eliminate them is shown.
