针对我厂低渗透油层地质条件复杂、选井选层难度大、压裂经济效益差等问题,从分析低渗透油田压裂改造难点入手,找出影响压裂效果的关健因素,应用测井曲线,确定垂直缝高度及裂缝延伸类型,对不同类型采取相应措施,实现了单层个性化设计。现场实施后,取得了较好的效果。 In view of the complex geological conditions, the difficulty of choosing well and the poor economic benefit of fracturing in low permeable reservoirs in our factory, starting with the analysis of the difficulty of fracturing in low permeability oilfield, the key factors influencing the fracturing effect are found, Curve, to determine the vertical seam height and type of crack extension, take corresponding measures for different types, to achieve a single-layer personalized design. After the implementation of the scene, achieved good results.
