摘要：煤层气受资源条件的约束采收率低，投资回报周期长，其相关工艺发展缓慢，严重制约了煤层气产业的勘助探开发进程，因此必须通过不断创新提升工艺效果、优化资源配置。分新认为利用地质导向建模的方法可以有效指导地质导向施工，从而提高水平并的开发效果。基于目前国内常用的地质乎向技术，介绍了利用模数拟合的思想来建立地质导向模型的流程，通过分新河东煤层气区块开发中遇到的实际案例，正当前水平并地质导向普遍存在的问题，并提出优化方案。从2016年已经完成的13口多分支水平井开发效果来分析，地质导向建模技术可以提升钻并品质进而改善产能。该技术提高了水平并开发的综合效率，为区块建设提供了技术保障，

Abstract: Due to the resource limitation of coalbed methane (CBM), its recovery factor is low and payback period is long. Besides, its related technologies are developed slowly. And consequently, the exploration and development progress of CBM industry is restricted seriously. Therefore, it is necessary to innovate and improve technological effects and optimize resource allocation. It is indicated from the analysis that geo-steering modeling technique can instruct geo-steering operation effectively to enhance development effectiveness of horizontal wells. In this paper, the workflow of geo-steering modeling based on the concept of Model-Compare-Update was introduced from the aspect of geosteering technologies that are commonly used in China. The most common issues of current horizontal well geo-steering were solved by analyzing the actual cases encountered during the development of Hedong CBM Block, and the corresponding optimization plans were proposed. The development effects of 13 multi-lateral horizontal wells implemented in 2016 were analyzed It is indicated that geo-steering modeling technique can improve drilling quality, and then increase the productivity. The Geo-steering modeling technique enhances the integrated development efficiency of horizontal wells and provides the technical guarantee for the construction of the block
