在Wilmington油田，基岩酸化有效地清除了地层伤害和结垢。该油田的大多数井都进行过多次酸化，大多采用常现的HCI／HF酸化，初期效果不错，但存在产量递减过快的问题。据猜测，其原因是由于结垢和细小颗粒运移导致堵塞孔喉而引起的。采用膦酸与HF混合后的化学改性酸（CM）进行
In the Wilmington field, bedrock acidification effectively removes formation damage and scaling. Most of the wells in the field are acidified for many times. Most of the wells are acidified by the conventional HCI / HF. The initial effect is good, but there is a problem that the output decreases excessively quickly. It is speculated that the reason is due to fouling and small particles caused by migration caused by blocking the pore throat caused. Using phosphonic acid and HF mixed chemically modified acid (CM) carried out
