摘　　要：通过数值模拟、技术经济评价等方法,确定了靖边气田马五1+2储层经济界限渗透率,建立了水平井适应性评价标准。根据碳酸盐岩储层天然气富集规律,综合储层横向预测、岩溶古地貌恢复、小幅度构造精细描述等技术方法,建立了水平井井位优选技术及其部署原则。By numerical simulation,and technical and economic evaluation,the economic limit permeability of 1+2 reservoir of Ma 5 Formation,Jingbian gasfield,is determined; and then,an evaluation standard for adaptability of horizontal well is established.According to gas accumulation regularity in carbonate reservoir and some technologies of reservoir lateral prediction,karst paleogeomorphic restoration and fine description of low-amplitude structure,a new technology of well-location optimization of horizontal well is established.Its application shows that it is effective for development of horizontal well,especially in relatively tight area.
