Abstract There are many factors which influence the absolute open flow potential (AOFP) of gas well. One them is angle between maximum principal stress direction and natural fracture strike in reservoir. In order to find out how influences AOFP A lot data related well productivity 14 wells located reservoir T were collected collated. Influential intensity each factor on before after modificatio...

The design trajectory parameters of 3D horizontal wells in X gas field are not uniform, the construction is random, and lack standardization enough to achieve rapid drilling. Based on analysis data difficulties completed well, according different types, by standardizing drilling tool assembly well design, making full use characteristics formation law, using supporting tools control sand carryin...

Abnormal pressure in the annulus is one of main risks that threaten safe production gas wells and affect their efficiency. To further improve well management level based on gray system theory new information priority ideology, this study introduced a perspective. First, we considered influence various factors related to change performed grey correlation analysis. Next, established multivariable...
