页岩气开采中的液化石油气无水压裂技术

LPG Waterless Fracturing Technology for Exploitation of Shale Gas

水资源的大量消耗和压裂导致的相关污染一直以来都是页岩气开采中常用的水力压裂技术始终面临着两大难题。为了实现页岩气能够绿色高效地开发,探索适宜的新型无水压裂技术已经显得十分重要和紧迫了。而目前,外国的石油科研人员正在研发的LPG无水压裂,即使用液化石油气作为压裂液,则可能是打开中国页岩气资源的钥匙。这种技术可以解决我国尚无完善水力压裂作业体系和缺乏水资源的情况,应用前景相当广阔。

The large amount of water resource consumption and related pollution caused by fracturing are two major problems in the exploitation of shale gas by using the common hydraulic fracturing technology. In order to realize the green and efficient development of shale gas, it is very important and urgent to develop new type of fracturing technology. At present, foreign oil researchers are developing LPG waterless fracturing technology, namely using liquefied petroleum gas as fracturing fluid; it may be the key to open shale gas resources in China. This technology can solve the problems that there is no perfect system of hydraulic fracturing operations and the lack of water resources in China, so its application prospect is very broad.
