完成的一组试验清楚地表明钻井泥浆可对裂缝造成严重的不可逆的损害，并可大大降低从天然裂缝网络中产油的那些生产井的产油量。将筛分的纤维作为钻井泥浆的添加剂可显著地降低地层损害的深度和范围。粒状添加剂（如CaCO3）效果差得多。因此，建议使用酸溶性的纤维，以降低裂缝性油藏中的地层损害。
The completed set of tests clearly demonstrated that drilling muds can cause severe irreversible damage to the fractures and greatly reduce oil production in those producing wells that produce oil from natural fracture networks. Using the sifted fiber as an additive to drilling mud can significantly reduce the depth and extent of formation damage. Granular additives (such as CaCO3) are much less effective. Therefore, it is advisable to use acid-soluble fibers to reduce formation damage in fractured reservoirs.
