沙特阿拉伯地区的碳酸盐油藏因钻探泥浆和地层固体颗粒而形成滤饼 ,使得油井产能下降。钻井后 ,在井眼稳定性岩石力学研究的基础上 ,怀疑常规的HCl增产措施会导致地表冲溃和井眼增大。而乳化酸措施在碳酸盐油藏中可形成深部酸蚀孔洞 ,起到射孔作用 ,既可防止钻井污染 ,又可保持地层完整性。 Carbonate reservoirs in Saudi Arabia form filter cakes due to the drilling of mud and formation solids, resulting in a drop in well productivity. After drilling, based on wellbore rock mechanics studies, it is suspected that conventional HCl stimulation will result in surface run-off and borehole enlargement. The emulsified acid measures can form deep acid-etched pores in carbonate reservoirs and play a perforation effect, which can prevent drilling pollution and maintain formation integrity.
