Study and Application of BH -WEI Tri -high Drilling Fluid

摘要：

In worldwide drilling operations today, there are more challenges than before. We have to face HTHP environ ments,high contamination of gypsum and salt, horizontal and extended reach drilling, slim -hole, increasing de mands for the faster drilling and environmental and safety issue. Conventional drilling fluids have many limitations and problems in drilling operation. BH -WEI drilling fluid is a alternative solution for these challenging drillings, The applications shows that BH -WEI can provide super inhibition ability, thermal stability and resistance contamination of gypsum and salt, max density: 2. 50g/cm3,max temperature:over 220℃. It can meet the requirements of HTHP wells and complex gypsum formations. It would be the expected drilling fluid for HTHP wells and gypsum formation.
