Study of New Ultra-Temperature Polymer Fracturing Fluid Material

Abstract:

Nowadays, hydraulic fracturing has become the mainly treatment in low permeability reservoirs.Niudong buried-hill was located in the Baxian Sag of the Bohai Bay Basin. The charactristers of this natural reservoirs are summarized as :low porosity and ultra-low permeability ;complex storage types and complex fracture break and with ultra high temperature (200-210°C) ,In the past, 150°C fracturing fluid system was used in order to solve fluid fracturing efficiency low, quick acid rock reaction.Field test shown that it can’t meet target of greatly improve the output. So it is necessary to develop a novel 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.The novel high-temperature fracturing fliud provides a new material to stimulate ultra-high temperature, ultra deep formation to help maximize recovery efficiency. it has important strategic significance for exploration promotion of ultra-high reservoirs .
