| For the asp flooding airtight gathering and transportation system,the problem of deposition scaling,and carried out the deposition,scale content composition analysis and make a research of its formation mechanism,the single well set oil pipeline deposit samples collected from different parts,analyzes its macroscopic composition,and through the thermal characteristic analysis experiment to discuss the deposit critical phase of the shift(or dissolve)temperature and deposition(or dissolve)peak temperature interval,The pipeline,water blending of single well near the fire,around the smoke heating tube and so on to acquire the scaling things samples from different parts,scanning electron microscopy its microstructure,structure,energy spectrum analysis of its elements,chemical quantitative description of scale up,According to the scale and deposition thing indoor test results,clear the causes and scaling mechanism?Carry out a indoor simulation test that about the deposition,scaling rules and influence factors,according to the indoor experiment to realize the rules of oil,water blending pipeline and collection deposit heating furnace scaling,and give out the system of produced fluids properties,gathering and transportation system pressure,temperature and velocity of set-valued oil,water blending pipeline deposition,scale influence,optimize production parameters,guide the site operation,in order to slow down the single well set oil,water blending pipeline deposition of fouling?Evaluation of the role of anti-deposition agent,optimization of the anti-deposition agent reasonable dosage,gathering and transportation system operation parameters,and make a feasible scheme for asp flooding airtight gathering and transportation system to control the deposition and scale,and adopt a feasible measures to prevent the scale and make the field test,extended the asp flooding the cycle of scaling,ensure the normal production of single?... |
