Capillary pump down tool

摘要

A capillary delivery system includes a capillary pump down tool. The capillary pump down tool is pumped into a well until it engages a landing sub that is positioned in a lateral section of the well. The capillary may be a fiber optic cable secured to the pump down tool. When the pump down tool reaches a desired location in the well the fiber optic cable and/or sensors in the pump down tool will sense parameters in the well.

主权项

1. A capillary tube pump down assembly for use in a well comprising:
a landing sub positioned at a preselected location in the well, wherein the landing sub defines a seat facing uphole in the well; a tubing connected to the landing sub; a housing pumpable into the landing sub, the housing defining a passageway therethrough, the housing including a seating cup having a seating head facing downhole in the well for engaging the seat of the landing sub and, when engaged, preventing downhole movement of the housing relative to the landing sub such that the housing is positioned in the well at a desired location, the housing further having a plurality of sealing elements disposed about the housing and engagable with the tubing such that fluid pumped into the tubing will interact with the sealing elements to urge the housing through the tubing and into the landing sub; at least one gauge disposed in the passageway of the housing for sensing a parameter in the wellbore; and a capillary tube fixed in the passageway of the housing and moveable therewith, wherein the housing will engage the landing sub when the housing is pumped through the well into the landing sub; wherein at least a portion of the sealing elements engage an inner diameter of the landing face.
