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。
The main reservoirs of Su 54 block in Sulige Gas Field are Box 8, Block 1 and Block 2, which are the sedimentary facies of rivers and delta. Comprehensive analysis of drilling data, logging data and well logging data by statistical methods showed that the vertical thickness of 2, 13, and 21 sandboxes in box 8 was large and the lateral extension distance was far. The composite contiguous plane and physical properties Good, gas-rich, suitable for multi-tiered horizontal well development. According to the characteristics of block reservoirs and the drilling and logging parameters during the implementation of horizontal wells drilled in the block, the target advance, delay and level The implementation of the drilling process encountered how to adjust the mudstone and other issues, summed up the Su 54 block horizontal wells into the target-oriented approach 6, 3 horizontal section of the guidance method, the implementation effect is good.
