Risk Ranking and Well Control Measures of Drilling Blowout in Xinjiang Oilfield

Abstract:

In order to reduce the chance of wellflow and prevent well blowout accident that gets out of control in Xinjiang oilfield, considering the statistical data of the factors that influence the drilling blowout, a model of evaluating drilling blowout risk to Xinjiang oilfield drilling and geological environment based on fuzzy mathematics is established. The drilling blowout risk of each oilfield area in Xinjiang oilfield area has been ranked, and the result indicates that both the nanyuan piedmont tectonic exploratory development area and the kelameili gas field are the highest drilling blowout risk areas. This paper suggests that the well control ranking management should be implemented in the Xinjiang Oilfield. Various well control measures should be made according to different drilling blowout risk, and the risk ranking of drilling blowout should be included in well control design.
