The utility model is composed of a mixing tank, a gas-liquid separating tank, a mixing delivery pump, a gas-liquid mixer, a corrosion testing pipe, a gas buffer tank and a high-pressure gas bottle, wherein, the corrosion testing pipe is provided with corrosion hanging pieces. The utility model can simulate the actuality of field production, and besides, the utility model achieves the indoor completion of researches of corrosion factors and relevant corrosion evaluation researches of different oil gas aqueous medium characteristics and different production parameters of oil gas production, gathering systems and sewage treatment systems and meets the requirements of oil field scientific researches.
Description
The utility model relates to the how fast corrosion simulated proving installation of a kind of oilfield transportation system three-phase stream, belongs to the oilfield chemistry corrosion and protection and estimates the field.
Prolongation along with the oil-field development time, the injection and extraction system pipe network is generally aging, oil, gas, water mixed delivery system severe local corrosion, corrosion mechanism and the forecasting techniques of carbon steel in three-phase flow mixing transfusion system particularly, need set up a cover dynamic analog device, the different oil gas aqueous medium characteristics of simulated field production of hydrocarbons, gathering system, wastewater treatment and re-injection, different manufacturing parameter are studied corresponding corrosion factor, the prediction corrosion rate.Various factors such as water percentage, flow velocity, salinity, CO2, O2, H2S, bacterium etc. are made the influence of various factors to corrosion and the corrosion resistance evaluation of unlike material clear to the influence of corrosion of carbon steel speed, etch state in the mixed defeated process of simulation three-phase.Domestic still do not have at present can simulation oil field gathering system oil, the device of the corrosion test system of gas, water three-phase medium flow state.
The purpose of this utility model just provides the how fast corrosion simulated proving installation of a kind of oilfield transportation system three-phase stream.
The purpose of this utility model is achieved in that the how fast corrosion simulated proving installation of oilfield transportation system three-phase stream is by mixing tank, knockout drum, mix defeated pump, air and liquid mixer, the corrosion test pipe, the gas buffer jar, gas cylinder is formed, knockout drum communicates with mixing tank by gas-liquid separation pipe and liquid back pipe, the import that mixes defeated pump connects mixing tank, outlet connects air and liquid mixer, the gas buffer jar is connected to gas cylinder, the import of air and liquid mixer connects the outlet of gas buffer jar, the outlet of air and liquid mixer links to each other with the corrosion test pipe, three-phase medium in the other end of corrosion test pipe and the mixing tank reclaims and mouthful links to each other, and on the corrosion test pipe corrosion coupon is housed.
The utility model can be produced actual by simulated field, realized that production of hydrocarbons, gathering system, the different oil gas aqueous medium characteristics of sewage disposal system, the corrosion factor research of different manufacturing parameters and the corrosion evaluation research of being correlated with are in indoor finishing, satisfy the requirement of oil field scientific research, saved production cost.
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1: the utility model structural representation;
As shown in Figure 1, the how fast corrosion simulated proving installation of oilfield transportation system three-phase stream, by mixing tank 1, knockout drum 2, mix defeated pump 3, air and liquid mixer 4, corrosion test pipe 5, gas buffer jar 6, gas cylinder 7 is formed, knockout drum 2 communicates with mixing tank 1 by gas-liquid separation pipe 10 and liquid back pipe 11, the import that mixes defeated pump 3 connects mixing tank 1, outlet connects air and liquid mixer 4, gas buffer jar 6 is connected to gas cylinder 7, the import of air and liquid mixer 4 connects the outlet of gas buffer jar 6,4 outlets of air and liquid mixer link to each other with corrosion test pipe 5, three-phase medium in the other end of corrosion test pipe 5 and the mixing tank 1 reclaims mouthfuls 8 and links to each other, and corrosion coupon 12 is housed on the corrosion test pipe 5.
During test, at first with oil, aqueous medium adds in the mixing tank 1 by a certain percentage, stir and be warming up to design temperature, press design current velocity again and start mixed defeated pump 3, treat oil, after aqueous medium operates steadily in corrosion test pipe 5, in gas buffer jar 6, inflate body medium by gas cylinder 7 by designing requirement, and then by gas buffer jar 6 to oil, add gas in the aqueous medium, finally make oil, gas, the water three-phase medium is evenly by air and liquid mixer 4 and corrosion test pipe 5, All Media is got back to mixing tank 1 back and carry out gas-liquid separation in knockout drum 2, and liquid circulates in system by mixing defeated pump 3 once more.After reaching design time, by 12 test evaluation corrosion rate and the antiseptic effects of the corrosion coupon in the corrosion test pipe 5.
