Research On Scale Control Technique For Theasp Flooding Produced Liquid

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