天然气水合物开发安全检测技术应用研究

Application Research on Safety Control and Measure Technology in Gas Hydrate Exploitation

摘要:

中国近年来先后在南海北部和祁连山南缘青海省天峻县永久冻土带中发现天然气水合物，这是一种新能源，它将对中国能源结构的调整和能源紧张的缓解起到非常重要的作用。但是，天然气水合物开采安全是个大问题，已经引起了国际上专家们的极大关注。俄罗斯南方国立技术大学地球物理、探矿工程和石油钻采教研室开发出来的天然气水合物开发安全检测技术和方法，可以准确确定出射孔部位的位置、检查射孔部位是否阻塞和如何解阻等关键技术，对天然气水合物开采安全提供了技术支撑，对此应该进行研究。

Abstract:

For recent years gas hydrate has discovered in northern part of Southern ocean and in frozen zone of southern fringe of Qilian mountain, in Qinghai province, Tianjun county in China .This new energy source will play an important role for adjusting energy resources structure and relaxing the energy resources tension of China. But, the exploitation of the gas hydrate and its security are serious problem in the World. The Teaching group of geophysics, exploration engineering and oil drilling engineering of South Russian State Technical University has developed a technology and methodology system of safety controlling and measuring. With the system the position of CT perforation part and the blocking up of the part can be determined and what corresponding measures to solve the blocking up should be taken. Therefore the system provides a technical support for safety exploration of gas hydrate.
