Abstract

Abstract

Mud losses are frequently encountered in the west Shaanbei area, especially in Tiebian town of Wuqi County. Severe mud losses sometimes resulted in hole abandonment or sidetrack, hence high drilling cost in this area. By analyzing the characteristics of the cores taken from Tiebian town and performing mechanical testing on the cores, it was found that what caused the mud losses were mainly the inter-connected flow channels formed by propagation and extension of micro-fractures as well as the communication of natural fractures. Based on this understanding of the mud losses, a lost circulation control slurry was formulated with rigid particles (for bridging), flexible deformable agents (for packing) and fiber materials (for intertwined connection) through simulated experiment. In laboratory experiment the lost circulation control slurry was able to bear pressure of more than 7 MPa. Three times of trials of this slurry in field application were all succeeded in the first try, and the pressure bearing capacity (equivalent density) of the thief zones was increased by 0.22 g/cm³. The successful application of the lost circulation control slurry provided a technical support to the prevention and control of lost circulation in the area of application.
- Mud losses into fractured formation,
- Extension of micro-fracture,
- Bridge with particles,
- Pressure bearing of formation,
- Tiebian Town area
