New Material Research of 200°C Ultra-High Temperature Fluid in Hydraulic Fracturing Industry Design Technology

In order to solve NiuDong101 Well reservoir ultra high temperature (205 °C ) fluid fracturing low efficiency, quick acid rock reaction which usually adopt the 160°C fracturing fluid system. At the same time to meet the deep acid fracturing technology and greatly improve the output, so as to achieve the production increasing reserves of important target. So it is necessary to develop a novel 200°C fluid system to achieve high-efficient stimulation. Therefore, this paper invented a new high temperature resistant ternary anionic thickener, and launched some fracturing fluid performance evaluation. This fluid system achieved 176mpa.s under the condition of 200°Cand 170s-1of RS600 which can perform good temperature resisting & shearing resistance performance, breakthrough the limit of 200°Cof fracturing fluid temperature resistance. Field application to achieve a major breakthrough, it has important strategic significance for exploration promotion of bohai bay basin.
