    摘要: Apparatus and methods for determining suitable displacement fluids for use in subterranean cementing operations, and methods of cementing that use such displacement fluids, are provided. Examples of methods include methods of water-wetting an annulus in a subterranean formation having an oleaginous-external/aqueous-internal fluid disposed on at least a portion of one or more surfaces of the annulus. Another example of a method is a method of using an inverter fluid in a subterranean formation that includes a tubular string disposed therein having an annular region adjacent the outer surface of the tubular string, at least part of the annular region having an oleaginous-external/aqueous-internal fluid on a surface thereof. Another example of a method of the present invention is a method of identifying an inverter fluid to use for inverting an oleaginous-external/aqueous-internal fluid in a subterranean formation.

    摘要: Cementing compositions and methods of cementing in a subterranean formation are provided. The cement composition includes a hydraulic cement, lightweight beads, and a desegregating agent for inhibiting segregation of the beads. The lightweight beads may be, for example, cenospheres, glass spheres, and ceramic spheres. The desegregating agent comprises a particulate substrate such as precipitated silica. It also comprises a polar molecule producing chemical disposed on the particulate substrate. Preferably, the polar molecule producing chemical is absorbed on the particulate substrate. The polar molecule producing chemical comprises at least one of a polar molecule producing acid such as glacial acetic acid, a salt of such an acid, and an acid anhydride. The method of cementing includes forming a pumpable slurry using the cement composition, pumping the slurry into a subterranean formation, and allowing the slurry to set.
