CALCULATION OF SKIN-EFFECT OF COMPRESSION AND CLOGGING UNDER THE REAL DATA OF OPERATION

For operative work at regulation of an operating mode of a chink, and also for calculation of stocks and for working out designing it is necessary to have on each chink the fact sheet about skin-effect which reduces an oil and gas output. On a practical example it is shown a technique of definition of skineffect of clogging Sкол and skin-effect of compression Sсж. It appears that for collectors of the raised permeability (more than 300 mD) at real depressions of operation Sсж there is more than value Sкол. At the same time in practice the size Sкол is defined is inexact on single sampling Curve of restoration of pressure, and the size Sсж is simply ignored, as about it it is not known.
