地质导向是水平井钻井成功与否的关键,其中涉及数据类型多、数量大,处理困难、无法直观判断等因素使得人工导向的成功率较低。近年来,随着信息技术与勘探开发业务的不断融合,处理空间数据的专用地质软件被开发出来用于水平井导向中,取得了良好效果。本文介绍了一种以处理多尺度、多时相、多类型的空间数据为基础的,集合地质、测井、三维建模、地质制图等方面的新型多源空间数据集成处理软件,该软件能够辅助导向工作者有效地识别储层,实时优化钻井轨迹,提高了导向的准确性。软件在鄂尔多斯盆地云页平X井地质导向中的应用,提高了相关数据的处理效率,保证了水平井钻井的成功率,是信息技术成功应用于水平井钻井的典范。
Geosteering is the key to the success of horizontal well drilling, which involves many types of data, large numbers, difficult processing and inability to judge directly, which leads to a lower success rate of manual guidance. In recent years, with the continuous integration of information technology and exploration and development, specialized geological software for dealing with spatial data has been developed for horizontal well guidance and has achieved good results. This paper introduces a new type of multi-source spatial data integration processing software based on multi-scale, multi-temporal and multi-type spatial data, which integrates geology, logging, 3D modeling and geological mapping. The guidance workers effectively identify the reservoir, optimize the drilling trajectory in real time and improve the guidance accuracy. The application of software in the geosteering of the Yunping Pingxu well in the Ordos Basin has improved the processing efficiency of related data and ensured the success rate of horizontal well drilling. It is an example that information technology is successfully applied to horizontal well drilling.
