    摘要: The present invention is a method for treating a subterranean wellbore. More specifically, the invention is a method for removing wellbore solids. A first, polymer containing fluid is placed in the solids bed. A second, viscosifying fluid is then placed into the solids bed thereby agitating the solids in the bed and causing the formation of a gel capsules when mixed with the biopolymer fluid. These gel capsules are capable of trapping or entraining the agitated solids. The gel capsules typically have a relatively high volume and a relatively low density, thereby making their removal from the wellbore easier.

    摘要: A formation consolidation process is described which comprises injecting into an unconsolidated or poorly consolidated subterranean formation penetrated by a wellbore an aqueous pumpable system comprising an insoluble silica source (e.g., colloidal silica, silica fume or fumed silica) and a source of calcium hydroxide (e.g., aqueous solutions of calcium chloride and sodium hydroxide). The aqueous system may contain a nucleation inhibitor. The components of the aqueous system react to produce a calcium silicate hydrate gel (C-S-H gel) having cementitious properties within the pores of the formation. After the C-S-H gel sets and hardens, the consolidated formation has a high compressive strength (e.g., 500 psi (about 3.5 MPa) or more). The technique can be performed as a remedial treatment or in new completions, but it is particularly useful in workover treatments for existing wells.
