低油价下致密油资源开发现状及应对

致密油已成为美国原油产量增长的主要来源,其国内超过80%的致密油产量来自巴肯、鹰滩和二叠盆地。致密油产量的增长由水平井不断增长的初产率驱动,新井产量的快速提升则主要源于压裂水平井带来的致密油产量的提升。在低油价影响下,美国国内致密油开发陷入产能衰退。当油价降至50美元/桶时,仅约三分之一的致密油产区能够实现盈利。我国陆相致密油具有多种类型,地质条件颇为复杂,致密油开发整体尚处于起步阶段。各致密油区块的开发在低油价下难以实现经济效益。面对低油价,石油行业可从技术创新、降低成本、政策扶持等方面来应对,力求实现致密油开发的技术可行到经济可行,以实现致密油资源的规模有效动用。

Research on the tight oil resources development present situation and countermeasures against low oil prices

The tight oil has become the main source of America"s crude oil output growth. More than 80% production comes from Bakken, Eagle Ford and Permian regions. Tight oil growth has been driven by increasing initial production rates from horizontal wells. Rapid upgrade production of new well is due to fractured horizontal wells bringing fast lifting for tight oil production. America"s tight oil development is in productivity decline because of low oil prices. When oil prices fall to $50 per barrel, only around one third of tight oil regions can make profits. Continental tight oil in China has many types with complex geological condition while its development is still at the starting stage as a whole. The development of each tight oil block is difficult to achieve economic benefits under the low oil prices. Countermeasures against low oil prices for oil industry could include technological innovation, costs reduction and policy support. The purpose is striving to achieve technically feasible to economically feasible of the tight oil development in order to get scale effective use of them.
