摘要
苏里格气田苏54区块主力储层为盒8段、山1段、山2段,为河流-三角洲沉积相环境。用统计学方法综合分析钻井资料、录井资料、测井资料,结果显示盒8下2、山13、山21砂体垂向厚度大、横向延伸距离远、平面上复合连片,储层物性好,含气性高,适合多层系水平井开发。针对区块储层特点,结合区块内完钻水平井在实施过程中的钻井、录井参数,系统研究了水平井在"入靶"过程中遇到的靶点提前、滞后及水平段实施过程中钻遇泥岩如何调整等问题,总结出了适合苏54区块水平井6种入靶导向方法、3种水平段导向方法,实施效果良好。
Main gas Su54 block in a reservoir for He8, Shan1, Shan2, for river delta sedimentary facies in the environment. Using statistical method comprehensive analysis of drilling data, logging data, the results show that the He8x2, Shan13, Shan21, vertical thickness of sand body, plane and horizontal extension, distance, composite laminated plate, a good reservoir property, hydrocarbon content is high, suitable for the multi horizontal well development. According to the characteristics of the block reservoir, combined with block within 7 horizontal well drilling in the implementation process, the logging parameters, system horizontal wells is studied in the process of ＂target＂ to meet the targets in advance, hysteresis and horizontal drilling in the implementation of the mudstone problems such as how to adjust, summarized suitable for Sue 54 block six horizontal well into the target oriented method, three methods of horizontal section of the guide, the implementation effect is good.
