【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。分析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,从而提高水平井的开发效果。基于目前国内常用的地质导向技术,介绍了利用模拟拟合的思想来建立地质导向模型的流程,通过分析河东煤层气区块开发中遇到的实际案例,纠正当前水平井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井品质进而改善产能。该技术提高了水平井开发的综合效率,为区块建设提供了技术保障。
[Abstract]:Coal-bed methane (CBM) is restricted by the resource condition, the recovery efficiency is low, the investment return period is long, and the related technology development is slow, which seriously restricts the exploration and development process of CBM industry, so it is necessary to improve the technological effect through continuous innovation. Optimization of resource allocation. It is considered that the method of geological guidance modeling can effectively guide geological guided construction, thus improve the development effect of horizontal wells, based on the geological guidance technology commonly used in China at present. This paper introduces the process of establishing geological guidance model by using the idea of simulation and fitting. By analyzing the actual cases encountered in the development of coalbed methane blocks in Hedong, the problems commonly existing in geological guidance of horizontal wells are corrected. In 2016, 13 multi-branch horizontal wells have been completed to analyze the development results. Geological guidance modeling technology can improve drilling quality and productivity, which improves the comprehensive efficiency of horizontal well development and provides technical guarantee for block construction.
