Design And Research On Super High Pressure Quick Connector Device In Fracturing Ship

With the rapidly decreasing global reserves of oil and gas,Continental petroleum resources shortage problem increasingly prominent,but the global economy will continue to drive demand for oil consumption,initial estimates that global oil consumption over the next 20 years will exceed 1.1 percent,so the offshore hydrocarbon resource which have abundant reserves and developing still shallow will become an important breakthrough to make up for the gap of oil supply and demand in our country in a long time in the future.Marine oil and gas field fracturing operation is done by fracturing workboat,during fracturing operation,all equipment are put in the boat,exhaust manifold through high pressure hose connected to the wellhead platform,in the case of emergency,require fast connection disengaged so that the boat can leave the job quickly and avoid loss of personnel and property,while protecting the operating equipment.Therefore,the pipeline connection between ship equipment and platform must ensure rapid and effective detachment.This paper puts forward a kind of super high pressure quick connector device in fracturing ship,the device can be closed ultrahigh pressure fracturing fluid,and realizes the automatic line out quickly,When in case of emergency,through the control system,release quickly,allowing the fracturing ship to evacuation quickly,which has the characteristics of high safety.Through system analysis and optimal selection,determine the quick connector device consists of a set of fast connector and a set of control system,and puts forward the overall scheme design.Design fast connection structure meet the functional requirements.and according to the working environment and technical parameters for the structure design of the hydraulic control unit.Complete detailed design of the fast connection,drawing 2 d technical drawings and 3 d digital model.Analysis the stress of work fast connection under different states in the process,finite element analysis to key spare parts by ANSYS Workbench,according to the analysis result to assess component bearing capacity.According to the requirement of fast out of the the quick connector device determine the control system is composed of electric control system and hydraulic system.According to the working principle of quick connector process,the hydraulic system of quick connector device was built,to simulate the working condition,to analysis the relevant simulation results.Design the corresponding circuit control system according to the hydraulic system.Draw the principle diagram of the electrical control system,to analyze working principle of the system.This article finally completed the overall design of the super high pressure quick connector device in fracturing ship.Fill the blank in the field of our country in this technology,provides technical support for further development of the research.
