Discussion of Construction Technology for Leakage Formations Treatment with Aerated Mud and Foam Mud

Abstract:

According to the complicated long-section well kick & circulation loss, loose and broken formations, the drilling method with foam mud or aerated mud is put forward to balance the formation pressure, which has dual role on wall protection and flushing fluid leakage prevention to realize continuous plugging and wall protection, and is helpful to improve drilling efficiency and reduce cost. This is a new technical means developed for drilling construction in water deficient area and full loss stratum.
