Research and Application of Acid Fracturing Technology in Subsalt Reservoir of Majiagou Formation in Daniudi gasfield
This article clarifies the acid fracturing characteristics of subsalt reservoir of Majiagou formation in the Daniudi gas field by conducting conductivity tests.Based on the fuzzy evaluation method,establish well layer evaluation standards to guide later layer selection.Based on the established mathematical model of acid fracturing in subsalt reservoirs,the acid fracturing construction parameters of the target reservoir were optimized to form acid fracturing processes suitable for different types of reservoirs.Through on-site application experiments,the yield increase rate has reached 20%,which has good promotional significance.
