Fracture Monitoring Technology Based on Surface Tiltmeter in "Well Factory" Fracturing

To obtain fracture geometry and azimuth in the "well factory" fracturing in the Daniudi Gas Field in order to guide the well pattern deployment and fracturing design, surface tiltmeters were used to monitor fractures induced in multistage horizontal well fracturing of two wells in Cluster R. Monitoring results were analyzed to understand fracture complexity using Simufrac. The research results demonstrated that complex fracture networks were developed due to induced stress which would lead to improved stimulation volume and performance in the simufrac of the two wells in Cluster R.This research will provide a theoretical basis forwell placement and fracturing design optimization in the near future.
