计量车标定过程中均为泄压标定,油井出液通过软管直接进入计量罐,原油中携带的伴生气排放,且不能真实反映油井正常生产时的出液情况,影响标定的准确性。因此,需要研制新型移动式单井计量装置,提高三叠系低产井带压标定和计量的精度。 During the process of calibration of the truck, the pressure relief calibration is carried out. When the oil well goes straight into the metering tank through the hose, the associated gas carried in the crude oil is discharged, which can not truly reflect the effluent condition during the normal production of the well and affect the calibration accuracy. Therefore, it is necessary to develop a new type of mobile single well metering device to improve the accuracy of pressure calibration and metering of low-yield wells in the Triassic.
