Abstract

An analogy between boiling liquid and the release of dissolved gas from oil is shown. The center of vapor release during boiling liquids is mechanical depressions on the boiling surface. The vapor bubble shape depends on the pressure in the liquid. The center of the gas in the oil stand fragments of rock formations, carried by the flow of oil. The rock, being hydrophilic, acts on the oil volume by surface repulsion forces. The surface repulsion forces create a pressure reduction on the unevenness of the rock fragments. In places of reduced pressure on the rock depressions, conditions for the release (formation) of a bubble are created. A piece of rock is a «maternal body» for a gas bubble. When a gas bubble is detached from a piece of rock, a new bubble immediately forms in its place, which ensures a continuous process of formation, growth and detach- ment of a bubble. The resulting formula for the separation coefficient proves the independence of the extraction process from the devices in the well.
