HIGH SOLIDS CONTENT SLURRIES AND METHOD |
摘要 |
A slurry and method are disclosed for low damage gravel packing. The slurry comprises a solids mixture comprising a plurality of volume-averaged particle size distribution (PSD) modes such that a packed volume fraction (PVF) exceeds 0.60; a carrier fluid in an amount to provide a solids volume fraction (SVF) less than the PVF of the solids mixture; and a stability additive to inhibit settling of the solids mixture. The method comprises circulating the slurry into a wellbore to deposit the slurry downhole; and terminating the slurry circulation for a period of time, wherein the stability additive inhibits settling of the solids mixture. Stability additives disclosed include colloidal particles, hydratable polymer particles, and particles having an aspect ratio above 6. |
