摘　　要：针对Oriente盆地东部斜坡带底水低幅度构造油藏的水平井开发难点,从低幅度构造的成因分析入手,介绍了以孔隙砂岩顶面构造解释和剩余构造分量为主要特点的低幅度构造解释和表征技术。在精细构造模型建立的基础上,提出了系统化的底水油藏水平井优化部署、精细地质设计和随钻监控的程序和方法,并在中厄合作的A油田的水平井开发中进行了成功应用。Horizontal well planning and design were real challenge to those reservoirs with low amplitude structure and bottom water in the eastern slope of Oriente basin. The key was to plot the locally low amplitude structure and predict the distribution of remaining oil.By analyzing the genetic origin of low amplitude structures in the study area,two techniques and methods for low amplitude structure interpretation and characterization were introduced,one was the detailed interpretation focusing on the top of porous block sand,the other was the calculation of structure residual amplitude.After the building of the structure model and the analysis of remaining oil distribution,the systemic procedures and methods are proposed for horizontal wells planning optimization,detailed geological design and integrated monitoring while drilling.As a result,great successes are made in the low amplitude structure mapping and horizontal well development in Oilfield A of China-Ecuador cooperation.
