Effect Analysis of Cross-layer Fracturing in Horizontal Wells

Abstract

This paper mainly analyzes the fracturing effect of horizontal wells in the development process of horizontal wells in low permeability A reservoir. On the basis of tracer monitoring, microseismic monitoring and production performance data, it is considered that fracturing breakthrough can be basically realized with the current fracturing scale of horizontal wells, but the actual breakthrough effect of communication layer depends on synchronous water injection to maintain formation energy. At the same time, the large-scale fracturing of horizontal wells can form a network fracture body in the formation, which is conducive to the production of oil layers near the well. Based on this conclusion, the next step is to formulate water injection policy for horizontal well development, so as to provide basis for future development research and water injection adjustment of horizontal wells in the same type of oilfield.
