目前大庆榆树林油田注水井投注时,基本采取不压裂投注方式注水。由于储层特低渗透、岩层致密,孔喉细小,注水井地层吸水能力差,造成注水困难,本文通过分析水井压裂的影响因素,结合目前的储层性质,完成榆树林油田水井压裂可行性分析与具体实施方法,给出了清水压裂的施工参数优化及实施思路。
Currently Daqing Yushulin Oilfield injection wells betting, the basic way to inject water without fracturing. Due to the extremely low permeability of the reservoir, the dense rock formation, the small pore throat, and the poor water absorption ability of the water injection well formation, water injection difficulties are caused. Through analyzing the influencing factors of the well fracturing and combining with the current reservoir properties, it is feasible to complete well fracturing in the Yushulin Oilfield Sex analysis and specific implementation methods, given the construction of water fracs optimization and implementation of construction ideas.
