Abstract:
The present invention relates to the field of drilling, and provides an anti-settling apparatus and a method and apparatus for checking the same, and an apparatus for preventing settlement of a well. The anti-settling apparatus of the present invention is installed in the wellhead region of the well during drilling to prevent the well from settlement. The anti-settling apparatus generally includes: an anti-settling base having an opening corresponding to the wellhead formed at the center thereof, the anti-settling base being disposed in the wellhead region during drilling; and an interlocking member  5  disposed at the opening to connect and fix a casing provided in the well with the anti-settling base. The apparatus for preventing settlement of a well comprises the anti-settling apparatus and checking method for the anti-settling apparatus.

Claim (Index 4):
A method for checking the anti-settling apparatus according to  claim 1 , wherein the method comprises:\n simulating a temperature field of an annular gap based on a flow rate of a drilling fluid and a temperature of a drilling fluid in a drill string; based on the temperature field of the annular gap and a temperature field of a permafrost where the anti-settling apparatus is on, determining permafrost parameters of a thawing region of the permafrost; determining a size of the anti-settling apparatus based on the permafrost parameters of the thawing region; determining amount of settlement of the well based on the size; and adjusting the size of the anti-settling apparatus based on the amount of settlement and a settlement amount threshold.
