STUDY OF HORIZONTAL MULTISTAGE HYDRAULIC FRACTURING OF A RESERVOIR

摘要

Horizontal well drilling technology has gained widespread popularity in recent years, especially for developing shale gas fields. In this paper, we propose a 3D model for calculating process parameters, based on the hypothesis that an elliptical crack forms as a result of hydraulic fracturing. Calculations according to this model can be used to determine the net pressure and the stress distribution near the cracks formed.
