Materials of well drilling and Maintenance methods for making and using the same

摘要

A method for maintenance of well drilling in an underground formation which comprises preparing a Fluid maintenance of drilling Well, comprising a Particulate material, a base Fluid, Aqueous fluid and a macromolecular Surfactant, linseed,And place the maintenance of well drilling Fluid in Drilling well and / or Training ground for consolidating and / or improve the conductivity of at least a portion of the drilling well and / or Training Ground.A method for maintenance of well drilling in an underground formation which comprises preparing a Fluid maintenance of drilling Well, comprising a Particulate material, a water-based Fluid, a Fluid Oil, and a macromolecular Surfactant, where the material Particulate matter includes Sand,And the macromolecular Surfactant comprising a hydrophobically modified polyethyleneimine, and place the maintenance of well Fluid in Drilling well and / or Training ground for consolidating and / or improve the conductivity of at least a portion of the drilling well and / or Training Ground.
