Methods of uniformly introducing aqueous treating fluids into subterranean producing zones are provided. The methods are basically comprised of the steps of packing perforation tunnels in the producing zone with a particulate solid anhydrous borate material which degrades and dissolves in water over time. A treating fluid is then introduced into the subterranean zone by way of the packed perforation tunnels whereby the treating fluid uniformly flows into the producing zone. The particulate solid anhydrous borate material in the perforation tunnels is allowed to degrade and dissolve in an aqueous fluid in contact therewith so that the aqueous fluid and produced formation fluids freely flow into the well bore.
Présentation de méthodes permettant d'introduire des fluides aqueux de traitement dans des zones de production souterraines. Les méthodes comprennent essentiellement les étapes de remblayage des tunnels de perforation de la zone de production à l'aide d'une matière particulaire solide borate anhydre qui se dégrade et se dissout dans l'eau au fil du temps. Un fluide de traitement est alors introduit dans la zone souterraine au moyen des tunnels de perforation remblayés par lesquels le fluide de traitement circule uniformément dans la zone de production. La matière particulaire solide borate anhydre qui se trouve dans les tunnels de perforation peut alors se dégrader et se dissoudre dans un fluide aqueux avec lequel il est en contact pour que le fluide aqueux et les fluides de formation produits puissent circuler librement dans le puits de forage.
