Abstract
A method for moving fluid through a pipe in a wellbore includes placing at least two different fluids in the pipe and in an annular space between the pipe and the wellbore. Fluid is pumped into the pipe at a rate to achieve a desired set of conditions. Using a predetermined volume distribution of the annular space, an axial position of each of the at least two fluids in the annular space during the pumping the displacement fluid is calculated.
Claims20
A method comprising:
- receiving sensor-based measurements associated with pumping of fluid into a conduit in fluid communication with an annulus that is disposed between the conduit and an interior wall of a wellbore;
- determining a pump pressure and flow rate of the fluid based on the sensor-based measurements;
- determining an annulus pressure profile and flow regime profile based on the pump pressure, the flow rate, and rheological properties of the fluid pumped in the conduit and in the annulus, wherein the flow regime profile depends on density and viscosity of the fluid;
- and
- adjusting a fluid pumping rate of the fluid based on an analysis of the flow regime profile and the annulus pressure profile against at least one predetermined pressure profile to maintain the pumping of the fluid within a predetermined range to optimize bonding between the fluid, the conduit, and the interior wall of the wellbore.

A system for monitoring and controlling fluid movement through a wellbore comprising:
- a processor;
- and
- memory storing instructions that, when executed by the processor, cause the processor to:
- receive sensor-based measurements from electronic sensors, wherein the sensor-based measurements are associated with pumping of fluid into a conduit in fluid communication with an annulus that is disposed between the conduit and an interior wall of the wellbore;
- determine a pump pressure and flow rate of the fluid based on the sensor-based measurements received from the electronic sensors;
- determine an annulus pressure profile and flow regime profile based on the pump pressure, the flow rate, and rheological properties of the fluid pumped in the conduit and in the annulus, wherein the flow regime profile depends on density and viscosity of the fluid;
- and
- adjust a fluid pumping rate of the fluid based on an analysis of the flow regime profile and the annulus pressure profile against at least one predetermined pressure profile to maintain the pumping of the fluid within a predetermined range to optimize bonding between the fluid, the conduit, and the interior wall of the wellbore.
