METHOD FOR FINISHING A WELL
The invention relates to methods of drilling oil and gas wells. The method provides for sealing of permeable beds with hydromonitored jets of the drilling mud. In the intervals of non-productive intercalations the walls of the well are subjected to unsealing and to subsequent sealing at a speed of t...

| description | The invention relates to methods of drilling oil and gas wells. The method provides for sealing of permeable beds with hydromonitored jets of the drilling mud. In the intervals of non-productive intercalations the walls of the well are subjected to unsealing and to subsequent sealing at a speed of the hydromonitored jets which exceeds their speed during the initial colmatage. The invention may be used, in particular, for isolation of low-permeable rocks where the desired effect cannot be obtained by traditional methods for isolation of such rocks.
L'invention concerne des procédés de forage de puits de pétrole et de gaz. Le procédé permet de colmater les couches perméables à l'aide de jets hydrocontrôlés de boue de forage. Dans les intervalles non producteurs, les parois du puits sont soumises à un décolmatage et à un colmatage ultérieur à une vitesse des jets hydrocontrôlés qui dépasse la vitesse du colmatage initial. Le procédé de l'invention peut être utilisé en particulier pour isoler une roche de faible perméabilité, où l'effet souhaité ne peut être obtenu par les procédés traditionnels d'isolation. |
