Mixing System For Cementing Applications

摘要

A technique facilitates various types of cementing applications, such as a downhole cementing applications along a wellbore. The technique utilizes a mixer having a rigid body and a flexible skirt disposed along at least a portion of the interior of the rigid body. The mixer further comprises a cement blend inlet and a fluid inlet through which cement blend and fluid are introduced into the mixer to form a cement slurry. The flexible skirt is constructed to enable selective deformation, e.g. flexing, during formation of the cement slurry to reduce or prevent the formation of cement slurry caking within the mixer.

主权项

1. A system for cementing in a well, comprising:
a tubing string positioned in a wellbore to receive a cement slurry; a pump to deliver the cement slurry to the tubing string; and a mixer to mix the cement slurry prior to delivery to the pump, the mixer having:
a rigid body comprising a conical bowl;a cement blend inlet disposed at the top of the conical bowl to enable delivery of a powder cement blend into the conical bowl;a fluid inlet oriented to deliver a fluid tangentially into the conical bowl; andan inner skirt disposed along an interior of the rigid body, the inner skirt being selectively deformable to reduce slurry caking during mixing of the cement slurry in the mixer.
