摘要
为了提高伊拉克南部X油田水平井储集层钻遇率,进而实现提升产能的目的,以该油田内A井为例,从导向前的地质建模、导向中的着陆段入窗控制和水平段轨迹控制、导向后的完井分析三个方面系统阐述了水平井地质导向技术在该油田的应用。现场应用结果表明,最终储集层钻遇率达100%,最大限度地提高了储集层钻遇率,实现了对目的层的有效预测及跟踪,保证了井眼轨迹在储集层中有效穿行,从而确保后期开发的产能效益,并为该油田同类水平井地质导向提供了借鉴和参考。
In order to improve the horizontal well within the target interval in X oilfield in southern Iraq, and to achieve the purpose of increasing productivity, taking well A in this oil field as an example, the application of horizontal well geosteering technology in this oilfield is systematically expounded from three aspects: geological modeling before geosteering, the entry window control of landing section and trajectory control of horizontal section in geosteering, and completion analysis after geosteering. The field application results show that the ultimate drilling catching rate in the reservoirs is 100%, which improves the drilling catching rate in the reservoirs to the maximum extent, realizes the effective prediction and tracking of the target layer, ensures the effective well path in the reservoirs and good capacity for later development, and provides reference for the geosteering of the similar horizontal wells in the oilfield.
