| Abstract: | According to the principle and characteristics of multi-cluster staged fracturing and aiming at the difficulties such as the more tools, the higher throttle-friction and incapable of opening the intervals of uhra-luw permeability reservoir in the multi-level staged fracturing technology, this paper proposes a nmlti-eluster staged fracturing of horizontal well formed using water-snluble temporary plugging agent and researches the gel state, solubility and the compressive strength of temporary plugging agent. At last, this technology is successfully applied in some well of Daniudi Gas Field with the open flow capacity of 0.111milhlon m3/d. |
