Abstract: Aimed at the outstanding problem that drilling cuttings form mud balls during drilling operation in Bohai oilfield and based on analyzing the reason of formation of mud balls, a new type of anti-binding agent FNJ-1 has been developed. Results show that remarkable success has been gained in inhibiting drilling cuttings bonding when using FNJ-1 in several hundred
wells of Bohai QHD32-6 oilfield.

Key words: directional well, drilling cuttings, mud balls, anti-binding agent
