Hydraulic fracturing case analysis of a well in Bohai
With the growth of oil and gas production in Bohai oilfield,the conventional operation of oil and water wells is increasing rapidly.The fracturing technology is limited by the factors of deep buried oil layer,complex wellbore structure,small construction site and high operation cost.In recent years,there are few fracturing operations from barracks.The fracturing well analyzed in this paper is the only large-scale hydraulic fracturing well implemented in Bohai self-supporting oilfield This paper introduces the fracturing scheme and operation process of the well,and analyzes various situations in the later stage of the operation.Although the final fracturing result of the well is not ideal,the optimization of the process scheme,the simulation calculation of the mechanical parameters of the string,and the evaluation and analysis after fracturing in the construction scheme have reference and guidance significance for the fracturing operation of most offshore oil wells.
