The main hydrocarbon reserves of the largest gas fields, currently developing in the north of Western Siberia, are confined to the Cenomanian deposits having weakly-cemented sand reservoirs. Solid particles are typical for well production of such deposits, especially during the late stage of its development. One of the most pressing problems during the well operation is destruction of the reservoir skeleton and withdrawal of sand at the wellhead, as it leads to abrasive wear of the ground equipment. Up to the present, no reliable criterion was proposed to prove the maximum allowable well flow rate, excluding occurrence of an emergency due to destruction of wellhead equipment with the withdrawing sand.
This presentation demonstrates a numerical study of erosion of pipeline elements using a general-purpose software, STAR-CCM+.
