摘要： A method of initiating fluid circulation in a well bore (6) through a casing (3) inner diameter and an annulus (5) outside the casing, the method having the following steps: inducing an increase in the annulus fluid pressure; flowing cement composition into the annulus 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 cement composition has entered the annulus to drive fluid circulation by the added cement composition weight. A method of cementing a casing in a well bore, wherein an annulus is defined between the casing and the well bore, the method having the following steps: connecting a circulation fluid pump to the casing inner diameter; pumping circulation fluid out of the casing inner diameter, whereby fluid flow in a reverse-circulation direction through the casing inner diameter and annulus is initiated; maintaining fluid flow in a reverse-circulation direction through a well bore annulus and the casing inner diameter until enough cement composition has entered the annulus to drive fluid circulation by the added cement composition weight; disconnecting the low-pressure cement composition pump from the annulus; and flowing additional cement composition into the annulus to complete a cement composition operation.

摘要： A cement mixing and pumping simulator comprises actual and virtual equipment. In response to an operator controlling this equipment, signals representing operating characteristics of a cement mixing system realistically represented by the actual and virtual equipment are generated. These signals are communicated for displaying the operating characteristics to the operator so that the operator obtains real-time responses to the operator's control of the actual and virtual equipment. A method of simulating operation of a cement mixing system comprises: operating, at a master control location within actual equipment of the cement mixing system, at least one actual control device of the cement mixing system; operating, at the respective location of each, at least one of the actual equipment located away from the master control location; determining characteristics of material flow through the cement mixing system in response to the operation of the at least one actual control device and the at least one actual equipment without actually flowing material through the cement mixing system; and displaying the determined characteristics in real time with the operating and determining steps. This method preferably further comprises recording data identifying a performance evaluation of an operator in response to a comparison between at least one of the determined material flow characteristics and a corresponding predetermined characteristic.
