Macromolecular Flow Improver Used for the Crude Oil Development

Article Preview

Abstract:

To overcome the shear-resisting challenge encountered in crude oil transportation, this paper analyzed the chemical composition of the crude oil transported through the Xinjiang-exporting pipeline and the structure of wax contained in the oil. Then, on the basis of the aforementioned analysis, a shear-resisting agent that is able to significantly improve the shear-resisting performance of the pour point and viscosity of the crude oil beneficiated with flow improver, was developed. Moreover, a macromolecular flow improver was developed by mixing a specific flow improver with the shear-resisting agent according to optimized proportions. The simulation experiment indicates that with the proposed macromolecular flow improver, it is likely to satisfy the technical requirement of normal-temperature transportation of crude oil through the Xinjiang-exporting pipeline.
