Fluid Loss Well Treatment

摘要

A well treatment for treating a well includes discrete stop loss elements to seal a fluid loss opening of a well. The discrete stop loss elements include polymer resistive to deformation with an initial stiffness in response to an initial strain rate of the polymer to produce a specified initial pressure signal and deformable with a subsequent, lower stiffness in response to a subsequent, lower strain rate of the polymer to produce a subsequent, different specified pressure signal.

1. A method, comprising:
initially plugging a fluid loss opening of a well with a plurality of discrete stop loss elements, the stop loss elements comprising a polymer, the polymer, while initially plugging the fluid loss opening, resisting deformation at an initial stiffness in response to an initial strain rate of the polymer to produce a specified initial pressure signal; and continuing to plug the fluid loss opening with the plurality of discrete stop loss elements, the polymer, while continuing to plug the fluid loss opening, deforming at a subsequent, lower stiffness in response to a subsequent, lower strain rate to produce a subsequent, different specified pressure signal.
