摘要：
Methods of forming gravel packs while reducing fluid loss to the surrounding subterranean formation. The methods involve suspending gravel that has been coated with a tackifying agent and degradable fines into a low viscosity carrier fluid and then placing that suspension into a subterranean formation so as to form a gravel pack wherein, as the gravel pack is placed, the degradable fines to de-adhere from the gravel and to fill at least a portion of the pore spaces within the gravel pack so as to reducing fluid loss through the gravel pack.
摘要（中）：
在减少对周围地层的流体损失的同时形成砾石包装的方法。 所述方法包括将已经涂覆有增粘剂和可降解细粉的砾石悬浮在低粘度载体流体中，然后将该悬浮液置于地层中，以形成砾石填充物，其中，作为砾石填充物，放置可降解细粉 从砂砾中去粘附并填充砾石包装内的孔隙的至少一部分，以便减少通过砾石包装的流体损失。
