Tahe Oilfield Ground Stress Analysis Model and its Application in the Barefoot Hole Wall Collapse

Abstract:

The T606 well in Tahe oilfield, deep core sample physical mechanical properties were tested to provide the experimental theoretical basis for casing failure analysis under the stress field. Afterwards, established the Tahe oilfield ground stress model based on the increasing fracturing data and related field ground stress models. The ground stress model is applied to calculate the critical level value of barefoot hole wall collapse in Tahe oilfield six and seven area. By regulating the production parameters and keeping borehole liquid level height above the critical level value, open hole collapse can be prevented.
