摘要
地质导向技术可基于井场实时随钻数据进行综合地质分析,并为水平井井轨迹调整决策提供准确的参考依据。而在复杂断块油藏中,由于断层影响因素的不确定性,常常导致地质导向的异常困难。以南海西部三口水平井为例,论述了水平井导向及断层识别技术在复杂断块油藏中的应用,并从实际应用角度阐明该技术在提高复杂油气藏钻遇率方面具有的重要指导意义。
The geosteering technology provides comprehensive geological analysis based on wellsite real-time data and accurate reference for well-trajectory adjustment decision.While in the complex fault block reservoirs,due to uncertainty of influencing factors arise from faults,it is unlikely to make geosteering have good effects.For instance,in this paper we actually tried three horizontal wells in Western South China Sea,and discussed the application of the geosteering and fault recognition technology in complex fault block reservoirs,as well as expounding its important directive meaning in improving the drilling catching rate in such reservoirs from the position of practical application.
