    摘要： A method of initiating fluid circulation in a well bore with a casing inner diameter and an annulus is provided. The method includes increasing the casing inner diameter fluid pressure at the top of the well bore; flowing a cement composition into the casing inner diameter at the top of the well bore; maintaining a difference in pressure between the fluid pressure of the casing inner diameter and the fluid pressure of the annulus until enough of the cement composition has entered the casing inner diameter to drive fluid circulation by the added cement composition weight; reducing the casing inner diameter fluid pressure at the top of the well bore while flowing a further portion of cement composition into the casing inner diameter; and pumping at a relatively higher fluid pressure the cement composition from the casing inner diameter into the annulus through a lower end of the casing.

    摘要： A method for cementing a casing in an open well bore having no surface casing, wherein an annulus is defined between the casing and the well bore, the method having: sealing the annulus at the mouth of the well bore with a seal; pumping a cement composition into the annulus through the seal; and taking circulation fluid returns from the inner diameter of the casing. A system for cementing a casing in an open well bore having no surface casing, wherein an annulus is defined between the casing and the well bore, the system having: a seal of the annulus at the mouth of the well bore; a cement composition pump fluidly connected to the annulus through the seal; and a coupling connected to the exposed end of the casing for taking circulation fluid returns from the inner diameter of the casing. A seal of a well bore annulus at the mouth of an open well bore having a casing extending there from and no surface casing, the seal having: an annular plug around the casing in the annulus below and proximate the mouth of the well bore, wherein the annular plug has conduit through the annular plug allowing fluid communication with the annulus below the annular plug; an anchor attachable to the casing above the annular plug; and at least one jack positioned between the annular plug and the anchor, wherein the at least one jack pushes the annular plug downwardly away from the anchor.

    摘要： Methods and systems for reverse-circulation cementing in subterranean formations are provided. An example of a method is a method of cementing casing in a subterranean well bore, comprising inserting a casing into the well bore, the casing comprising a casing shoe; equipping the casing with a well head, and a casing inner diameter pressure indicator; flowing an equilibrium fluid into the well bore; flowing a cement composition into the well bore after the equilibrium fluid; determining from the well-bore pressure indicator when the well bore pressure has reached a desired value; discontinuing the flow of cement composition into the well bore upon determining that the well bore pressure has reached a desired value; and permitting the cement composition to set in the subterranean formation. Examples of systems include systems for cementing casing in a well bore.
