Drill Fluid Technology for Well Qing2-50
摘要
Abstract
Well Qing2-50 penetrated formations that are very complicated. Water sensitive and brittle shales, fractured formations, dipping formations and formation stress all heightened the success of drilling operation. A cationic polymer drilling fluid treated with lime was used in drilling the upper section of the well. In the lower section, drilling fluid was converted to a cationic polymer sulfonate drilling fluid having a high temperature stability. Shale swelling and dispersion were inhibited by the strongly inhibitive cationic drilling fluid. The success of well Qing2-50 paved the road for a successful exploration of the block this well is located in.关键词
