Abstract
A downhole tool assembly includes a tubular having a turned-down region and a raised region extending axially away from the turned-down region. An inner diameter surface of the tubular in the turned-down region has a higher ellipticity than an outer diameter surface in the turned-down region. The outer diameter surface in the turned-down region defines a first center that is offset from a second center defined by the outer diameter surface of the tubular away from the turned-down region. The downhole tool assembly also includes a cylindrical tool disposed at least partially in the turned-down region.
Claims20
A downhole tool assembly, comprising:
- a tubular comprising a turned-down region and a raised region extending axially away from the turned-down region,
- wherein an inner diameter surface of the tubular in the turned-down region has a higher ellipticity than an outer diameter surface in the turned-down region, and wherein the outer diameter surface in the turned-down region defines a first center that is offset from a second center defined by the outer diameter surface of the tubular away from the turned-down region;
- and
- a cylindrical tool disposed at least partially in the turned-down region.
A downhole tool assembly, comprising:
- a tubular comprising a turned-down region and a raised region extending axially away from the turned-down region, wherein an inner diameter surface of the tubular in the turned-down region has a higher ellipticity than an outer diameter surface in the turned-down region;
- and
- a cylindrical tool disposed at least partially in the turned-down region, wherein a maximum diameter of the outer diameter surface is determined based upon a size of the cylindrical tool.
A downhole tool assembly, comprising:
- a tubular comprising a turned-down region and a raised region extending axially away from the turned-down region, wherein an outer diameter surface in the raised region along a portion of the tubular has a higher ellipticity than the outer diameter surface of the tubular in the turned-down region;
- and
- a cylindrical tool disposed at least partially in the turned-down region, wherein the cylindrical tool includes a plurality of ribs extending between a plurality of end collars.
