摘要:
随钻测井技术可提供地质实时导向,保持砂体产层高钻遇率。在缺少探井资料的井区,基于水平井随钻探边工具,利用方位等信息以及电阻率反演模型准确定位井眼轨迹,刻画砂泥岩性边界、油气水流体边界,再对包含了界面信息的轨迹线抽稀成点,弥补稀疏井网背景下约束井点不足的缺陷,实现高精度构造成图。该方法扩展了随钻测井技术在油气藏精细描述、储层建模中的应用,在东海某气田中的应用验证了方法的可行性。
Abstract:
LWD technology can provide real-time geo-guide and maintain high penetration rate of sand bodies. This paper introduces an application of high-precision structural mapping using bed boundary detection technology in fields lacking of exploration wells. Based on boundary detection tool, wellbore trajectory can be located accurately using information containing of azimuth etc., as well as resistivity inversion model. Thus, we can depict lithology boundaries and fluid boundaries. Through the trajectory line, we can dilute it into series of points, containing the details of interface, which can make up for the deficits of sparse wellbore network. The method extends the application of LWD technology in other aspects, such as fine reservoir description and reservoir modeling. Application in a gas field in the East China Sea verifies the feasibility and reliability of this method.
