Study And Application Of Technology For Oil Production Without Wellbore Heating In High Pour-point Oil Reservoir

virtual At present,the exploitation of high pour-point oil depends on wellbore electric heating which leads to high production cost for high pour-point oil,so transforming high pour-point oil production method is the key to lower production cost。This article describes the practice of laboratory study,evaluation,formula selection and application of cosolvent for oil production without wellbore heating,and through matching ground devices including twin line water blended oil production technology we implemented coventional cold production of high pour-point oil in moderate and high water-cut stage over and above low-yield and low water-cut high pour-point oil wells'normal production。The above-mentioned two ways of production resolved the problem of implementing cold production pertain to different fluid production rate,different water-cut oil wells in different blocks and found effective methods to lower the production cost of high pour-point oil。These methods can be popularized。This article mainly pointed out the suitability of cold production chemicals and its economic dosage in different wells, also pointed out hoisting links of twin line water blended oil production technology in oder to apply to field production。...
