Based on the drilling operation of 4 Wells, this article describes the basic characteristic of coalbed methane and technical difficulties in drilling. Some technical keys as borehole quality, fresh Water drilling,fresh water coring, coal-bed methane protection are solved through application of a series of techno1ogical measures such as optimization of rock bit, optimization of drill stem, optimization of drilling parameters and string coring and etc. The experimental performance, especially in fine-grained ...

本文以四口井的施工为例，着重介绍了煤层气井的特点，并指出了钻煤层气井的几个技术难点，通过钻头优选，钻具优选，钻井参数优选，绳索式取心技术等的现场实施和应用，基本解决了井身质量，清水钻井，清水绳索取心，煤层气保护等几个方面的技术难题，文中还介绍了使用中原油田自行设计的中原9508绳索取心工具的取心情况，尤其是在粉煤层地区的取心情况，这将为今后的煤层气开发打下坚实的基础。

The coring was successfully operated on the winter ice-cover of the lake in 2000 and the pioneer practice of the ""off-the-ice"" coring proves to be very useful and economic for taking quality cores from lakes in northern China.A multidisciplinary investigation has been carried out on core HQH4, one of the three 11-m-long cores. Results from previous investigation include lithostratigraphy, radiocarbon dating, paleoecology of Ostracoda, stable isotopic record of ostracod shells, total nitrogen and organic carbon, C/N ratio, 81 C of organic matter etc.

At the beginning, the common small diameter diamond coring drilling is used, but the efficiency is low, the cost is high, and the construction period is long. Subsequently, the hollow-through type DTH hammer drilling technique and continuous coring technology with reverse circulation are adopted to experiment in this mine.

中文摘要：新疆白干湖钨锡矿区自然环境恶劣，地质条件复杂，普通小口径金刚石岩心钻探方法效率低、成本高、施工周期长，后采用贯通式潜孔锤反循环连续取心钻进技术在本矿区进行生产试验。

The minimum required hardware for Windows 7 is as follows: a 1 gigahertz or faster 32-bit or 64-bit processor; 1 gigabyte of memory for the 32-bit version of Windows 7 or 2 GB for the 64-bit version; and 16 GB of available hard disk space for 32-bit or 20 GB for 64-bit.

Windows 7的最低系统要求如下：至少1GHz主频的32位或64位处理器、32位版本的Windows 7要求1GB内存和16GB可用的硬盘空间；64位版本的Windows 7则要求2GB内存和20GB可用的硬盘空间。
