Anshun 1 is a key risk exploration well. Based on the analysis of geological information, the engineering difficulties was confirmed and the drilling technology proposal on marine formation which is suitable for this block was formed through optimizing the well structure and selecting reasonable drilling method, drilling fluid system and matching drilling technologic measures. The well was successfully drilled to the objective interval with 5,478.91 m TD. The quality of well bore and cementing quality are qualified. The success of Anshun1 provides some guidance and reference for subsequent drilling operations in this block.
