Calculation Method of Earth Stress in Zhenjing Oil Fileld in China

Abstract:

The magnitude, distribution of earth stress are important parameters. In this paper, based on the hydraulic fracturing test data and logging data, the model of earth stress has been established. The vertical stress (S_v),the maximum horizontal stress (S_H), the minimum horizontal stress (S_h) can be calculated by logging data with this model. The profiles of earth stress along the depth with continuous distribution can be determined, and stress spatial distribution has been described.
