Hole WZK-4 of "Tanjianshan Gold Mine Exploration Project in Dachaidan Town, Qinghai Province" is a key exploration well. During the early stage of construction, the alluvial-diluvial layer is loose and expanded, the stratum is broken and collapsed, the diameter shrinks and the spalling phenomenon is serious, during the drilling process, it is difficult to raise and lower the drill, and it is necessary to clean the hole to the bottom each time the drill is lowered. Conventional polymer drilling fluid systems cannot meet the construction requirements. In view of that above complicate difficulties, a potassium-based film for flushing solution system is adopted, and the main formula is as follows: 0.1%~0.2% caustic soda +0.5%~ 1% soda ash +3%~ 5% sodium clay +0.2%~ 0.6% salt resistant polymer STQ+1%~2% filtrate loss agent +3%~ 5% film forming system SCM+0.1%~0.2% liquid viscosity increasing inhibitor SN+0.5%~1% sloughing prevention plugging agent while drilling +3 - 5%KCl, by incorporating film-forming SCM treatment agent and liquid viscosity enhancer inhibitor SN, the above complex issues have been resolved, and no such difficulties arose during the construction process. The density 1.03~1.11g/cm3, API=5.2ml, the quality of mud cake is thin yet tough, drilling quantity planned for the project is 300m, The actual final hole is 303.8m. The effective drilling time of Tanjianshan Gold Mine in Dachaidan is about 15 days, which is equivalent to about 74.54 yuan/meter of washing fluid material cost per meter of footage, which can provide reference for subsequent construction.
