Formation Damage due to Mass Transfer in the ...

Studies have shown that the same mechanism is responsible for the accumulation of huge energy in reservoirs and inability to obtain inflow from potentially productive layer. Considering the process of chemical adsorption in layers, it managed to show that when the fluid flows into the reservoir, even moderate magnitudes of over balance internal electromagnetic radiation occur. Under the influence of this radiation, certain order of direction and intensity oscillations of phonons is set. Regard to borehole maximum intensity, oscillations of phonons will take place in the zone of high tangential stresses. Therefore, at some depth from the borehole, wall rock will be destroyed into particles commensurable with clay. Behind the transition layer due to throw of electromagnetic energy into the reservoir and fluid, mass transfer from the periphery of the reservoir to an extended zone with stepwise increased porosity and high thermodynamic compressibility of fluid is formed. Inside this zone a strong and long-range interaction between particles of fluid is developing. Throw in of electromagnetic energy is a result of intensive electromagnetic radiation due to the inflow into the reservoir mud or kill fluid. This formation is called the associate. The associate emits electromagnetic waves that change over allogenic particles in porous medium beyond the associate in the excited state. Between associate and excited particle strong interaction set in, which manifested in attraction of particle to the associate, and it becomes a full member of the associate. Thus, there is a selective implication of allogenic fluid particles into the associate.
