    摘要： Improved well fluids that include hollow particles, and methods of using such improved well fluids in subterranean cementing operations are provided. Also provided are methods of cementing, methods of reducing annular pressure, and well fluid compositions. While the compositions and methods of the present invention are useful in a variety of subterranean applications, they may be particularly useful in deepwater offshore cementing operations.

    摘要： The current invention provides a method for enhancing the formation stability of water sensitive, reactive formations penetrated by a wellbore. The method of the current invention provides an accurate evaluation of the impact of cementing fluids on water sensitive, reactive formations and provides the ability to accurately formulate cementing fluids in order to enhance the stability of such formations. When necessary, the method of the current invention additionally provides for the application of an osmotic semi-permeable membrane to the face of the formation.

    摘要： An inflation packer method and apparatus comprising at inflatable packer bladder and an inflation fluid. The packer apparatus further comprises a packer mandrel having a central flow passage therethrough and an outer packer body which includes the inflatable packer bladder. A chemical expanding additive is employed to expand the inflation fluid used to inflate the packer bladder. An annular inflation fluid passageway is defined between the mandrel and the body. Inflation fluid passes from the central flow passage into the annular inflation fluid passageway to inflate the inflatable packer bladder. The mandrel has grooves defined on an outer surface thereof. The chemical expanding additive is placed in grooves defined on the outer surface of the mandrel so that the expanding additive is dispersed into the fluid passing into the annular passageway.

    摘要： A method of forming a kickoff plug in a borehole is disclosed. The method includes a first phase in which the interval to be cemented is treated to remove gelled mud and mud cake from the walls of the borehole and in which drilling fluid is conditioned for subsequent cementing operations. The method includes a second phase in which a hydrostatically balanced plug of a hydraulic cement slurry is placed in the interval to be cemented and then permitted to harden to form the kickoff plug. Each phase of the method features the injection of high velocity streams of fluid, e.g. drilling fluid and cement slurry, into the borehole in a plane or planes which are substantially parallel to the cross section of the borehole and at linear velocities sufficient to cause circulation of gelled mud, mud cake, and drilling cutting from the borehole.
