Research On Risk Control Of Downhole Well Control

Well control technology of downhole operation, is one of the most important job inconstruction engineering and security technology. Blowout out of control can lead to seriousconsequences. In the oil industry in all kinds of accidents, either from the number of accidentsor loss, blowout have come out in front. Aiming at the current situation of well control riskassessment, analysis of the causes of blowout out of control and the factors affecting the wellcontrol equipment failure reason, put forward the downhole operation common blowout typeand preventive measures. Through the fault tree analysis method for the analysis of wellcontrol system of human error factors in human factors, put forward prevention measures.Based on the analysis, proposed through the study of well control equipment detectiontechnology to build oil extraction factory own well control workshop, and the safetyevaluation, through the strengthening of well control workshop on well control equipmentinspection repair and technical services management, solve the equipment of well control areimportant factors to restrict. According to the production plant is specific and actual, thedownhole well control all aspects of the decomposition, analysis of blowout out of controlcaused by specific factors, from well control equipment, well control technologyimprovement were put forward from the aspects of oil production plant underground blowoutspecific risk prevention measures, for thick oil steam flooding process technology of specialrequirements, to heavy oil thermal recovery well control risks and preventive measures werediscussed technically. Proposals to strengthen the abnormal high pressure oil wells wellcontrol management, to develop as soon as possible snubbing operation technique study andapplication to achieve the system to control the operation of downhole blowout risk.
