  • Studies on the mechanisms of borehole wall collapse and the drilling fluid capable of controlling the borehole wall collapse were performed to solve the problem of bad borehole wall collapse happening in drilling the Triassic System in the Yueman block, south bank of Tarim river. The Triassic System is mainly composed of mudstones and sandy mudstones containing 28.6% clay minerals in which 45% is the mixed layer of illite and montmorillonite. When in contact with water the formation rocks absorb the water, and the compressive strength of the rocks decreases. On the other hand, the density of the drilling fluid used is less than the equivalent density calculated from the collapse pressure of the formations. These are the the immanent causes resulting in borehole wall collapse. In field operation, the drilling fluid used had high filtration rate, leaving a thick mud cake with poor toughness. Laboratory test with the drilling fluid showed that the percent recovery of shale cuttings is low, while the linear expansion rate is high. Other shortages of the drilling fluid include poor plugging capacity and bad particle size distribution. A new drilling fluid was formulated based on these findings using optimized filter loss reducers, compound inhibitive additives such as FTDA. This drilling fluid has low API and HTHP filtration rates, and the mud cake is thin and tough. The percent recovery of shale cuttings with this drilling fluid was increased by 15.7% compared with the old mud. Plugging test on sand-bed showed that the plugging capacity of the new drilling fluid was increased by at least 50%, indicating that the drilling fluid has reasonable particle size distribution. In field application, the new drilling fluid had stable rheology and low filtration rate, no pipe sticking and borehole sloughing were encountered. The average rate of hole enlargement was 10.35%, which is 50.24% lower than the average rate of hole enlargement of the wells drilled in the same block. The application of the new drilling fluid has provided a new technical clue for stabilizing the borehole wall of the wells penetrating the Triassic System in the Yueman block.
