Fine Detection and Analysis of Hidden Karst in Wellsite with Quasi-Three-Dimensional TDEM Based on Lateral Constraint
Considering that karst caves, underground rivers, and dissolution fractures in shallow carbonate formation in the Sichuan Basin are extremely Shaving Cream developed, leakage, failure and plugging difficulties are easy to occur in the drilling process.The TDEM was used to carry out the exploration of hidden karst geological bodies in well QM2, and
