TECHNOLOGY FOR REMOTE SANDY CLAY CAPS FROM SLAUGHTER SPLITTERS GAS WELLS IN DEPRESSION
Abstract
Elaboration of technology for clay-sand plug removal from multi-branch gas wells by foam flushing of bottom hole under depression in the system «well-reservoir» is considered in the paper. Mathematical model and algorithm to calculate the bottom hole pressure and the velocity of up-stream flow when foam flushing of a well is given. Example of calculation of gas wells foam flushing at Kuschevskaya underground gas storage are given.
