    Abstract
  • Whole rock mineral analysis, clay mineral analysis and microstructure analysis of rock have been performed on rock samples taken from different formations to find the root causes of borehole wall instability encountered in the Fukang sag block. The analyses results indicated that it is the high content of kaolinite and large amount of micro pores and fractures developed in the formations that cause the borehole wall to loss its stability. Base on these borehole wall instability mechanisms, the oil based drilling fluid used to drill the well F49 was selected to determine the direction of mud property optimization. FD-FK, an amphiphilic polyacrylic acid resin, was synthesized as a cementitious plugging agent, and TQ-FK, a poly fatty acid was developed as a gelling agent, were developed for use in oil based drilling fluids. The oil based drilling fluid used in drilling the well F49, after treatment with FD-FK and TQ-FK, had its low-shear-rate viscosity and YP/PV ratio greatly increased, and the sizes of fractures that can be plugged by the drilling fluid were increased from 2～90 μm to 2～380 μm. The plugged fractures had pressure bearing capacity increased to 8 MPa, indicating that the oil based drilling fluid had good plugging capacity. The 3rd interval of the well Fu-47 was drilled with the oil based drilling fluid optimized with FD-FK and TQ-FK, the average percent hole enlargement of the problematic sections was only 3.35%. The application of this optimized oil based drilling fluid has provided a effective technical support to the safe and efficient drilling operation in the Fukang sag.
