Pulse-code well interference testing involves an integrated hardware and software solution of cross-borehole interference and claim a significant extension of the applicability of traditional Interference in practice.
The method of pulse-code Interference finds a ready sale due to a number of advantages compared with other hydrodynamic studies :
• In the course of a study on the disturbing well will be established a "special code" (by changing well mode ), which is allocated to the observation wells, which can significantly reduce the impact of foreign interference, not connected with valid signal,
• The possibility of determining the anisotropy of formationparameters and fluid flows in opposite directions;
• The ability to determine the position of the front during the frontal drive;
• Monitoring of time-cross parameter variation, defined by pulse-code interference method allows to determine best performance mode and detect violations preliminarily, for example:
üWater production for the annulus;
üDisable low-permeability interlayers
üAreal off low-permeability interlayers
üFluid loss in inter-well space, etc.
