摘　　要：根据Beggs-Brill的流动型态模型推导出了控制压力钻井环空多相流的压力计算公式;并提出了井口回压对环空流态的影响。提出的计算模型已通过现场试验的验证。试验结果表明其误差只有3%左右,能够指导现场作业。为控制压力钻井技术在大庆油田的应用和发展提供理论依据。According to the mobile state model of Beggs-Brill to infer the multiphase calculation formula of manage pressure drilling,the well head back pressure influence the annulus state is proposed.The computation model is proposed through the field test confirmation.The test result has indicated its error only then about 3%,could instruct the field operation.The theory basis for MPD in the Daqing Oil Field application and the development is provided.
