Drilling Fluid Technology for Extended-Reach Horizontal Wells in Cuba

Abstract:

This Extended-reach horizontal wells lies in Guanabo block of Cuba, using the KCl polymer drilling fluid system which has strong inhibition. To strengthen the drilling fluid inhibition, it keeps the concentration of GW FA-367 at around 0.5% in the construction, KCl is 8%~10%, GW POLYCOL is 2% ~ 3%, it also takes the use of other assorted maintenance treatment measures at the same time. The results of application show that, compared with other wells of this region, this well greatly shortens the drilling cycle, reduces the accident rate and the drilling cost, the drilling fluid lubricity is good.
