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 11):
The checking apparatus according to  claim 10 , wherein the permafrost parameters further comprise porosity of the permafrost in the thawing region, wherein the settlement amount determination module is further configured to:\n determine a volume compression coefficient of the permafrost in the thawing region based on the porosity; and determine the actual amount of settlement corresponding to the size according to the following formula:\n s=a 0 h+m v h\u0394p  \n wherein s indicates the amount of settlement, h indicates the thickness of the permafrost, a 0  indicates thaw-settlement coefficient of thawed permafrost, m v  indicates the volume compression coefficient of the permafrost, and the adjustment module is further configured to: increase the size by a predetermined value to re-determine the size of the anti-settling apparatus if actual amount of settlement exceeds the settlement amount threshold.
