Well Qian 16-16 is the first high deviated well in buried hill Qianmiqiao in Dagang Oilfield. To overcome the technical difficulties of acid fracturing in facture developing reservoirs of high-temperature deep wells, the acid fluid system suitable for this region was screened out, and acid fracturing technology and operating parameters were optimized. Separated tubing and casing pressure limit injection method was innovatively used to achieve the large scale displacement of acid fracturing. And good results were achieved. It opened up a new way of technology innovation for acid fracturing in this region and provided technical storage for the large-scale development of Qianmiqiao Oilfield.
