Nowadays, the large cluster well factory production mode is widely applied, which means that multistage fracturing can cause casing damage not only to construction but also adjacent well. To explore of deformation caused by fluid pressure intrusion in fracturing, a three-dimensional model two wells established based on natural fractures. The new has reached dimensions 1500 m × 300 100 m, essentially achieving 1:1 scale modeling. In addition, basis large-scale modeling, have been taken into...
In order to study the casing deformation and its causes in process of multi-stage fracturing shale wells, a full-scale finite element model formation is established based on actual wellsite data. The overall horizontal section at natural fracture after each stage are clarified. hydraulic expansion in-situ stress disturbance explained. influencing factors gas studied by changing treatment parameters. results show that wells will cause creep change field near zone, which damage casing. As...
Abstract With the wide application of extended reach wells and horizontal wells, geological conditions faced during drilling process have become increasingly complicated, resulting wellbole collapse problem has serious. Based on an L-1 well, this study provides a method for calculating pressure considering influence formation hydration. This is used to obtain stress distribution around well situation at 4100 m underground. The wellbore stability can be evaluated by method. factors affecting...
