摘要
针对西江23-1油田地层疏松、不易造斜、井轨迹控制难度较大等问题,引进了新型地质导向工具,采用新的地质导向技术。概要介绍了新型导向工具的特点和优势,重点介绍了密度成像技术判别地层倾角和依据衰减与相位电阻率的差别判断岩性的方法,通过实例分析了其应用效果。提出了具有针对性的地质导向过程及调整优化方案,保证了调整井地质导向工作的顺利实施。
As to the problems in Xijiang 23-1 oilfield,such as loose strata,the difficulties in whipstocking and controlling the well trajectory,etc.,a new geological-oriented tool is introduced and new geosteering techniques are adopted.The paper gave an overview about the features and advantages of new-oriented tools,highlighted the methods of distinguishing the formation dip by density imaging technique and identifying the lithology by attenuation and phase resistivity difference and analyzed its application effect by real instances.The authors provided the targeted geosteering process and adjustable optimize program to ensure the smooth implementation of geosteering for the adjustment wells.
