据外媒6月10日消息，因美国钻井数据显示钻井活动上升，美国原油期货周五跌至每桶50美元以下。
在全球一些地区供应中断加大了对全球原油供应过剩状况将比预期更快缓解的预期后，油价自今年创下10年低点以来已经飙升90%左右。
然而一些市场观察人士警告称，油价大幅上涨可能鼓励生产商提高产量，从而令市场继续供应过剩。
纽约商交所七月交割的美国原油期货结算价下跌1.49美元，至每桶49.07美元，跌幅2.9%，该期货本周上涨0.9%。
欧洲ICE期货交易所的布伦特原油期货下跌1.41美元，至每桶50.54美元，跌幅2.7%，该期货本周上涨1.8%。
贝克休斯公司周五公布，本周美国石油钻井平台数量增加三座，为连续第二周增加。

Oil Prices Fall Below $50 as Drilling Data Show Uptick
By Georgi Kantchev and Nicole Friedman
U.S. oil prices fell below $50 a barrel on Friday as U.S. drilling data showed an uptick in activity.
Oil prices have rallied by around 90% since hitting decade lows this year after supply outages around the world fueled expectations that the global oversupply of crude would shrink faster than expected.
However, some market watchers warn that the sharp rally could encourage producers to increase output, keeping the market oversupplied.
U.S. oil for July delivery settled down $1.49, or 2.9%, at $49.07 a barrel on the New York Mercantile Exchange. The contract rose 0.9% this week.
Brent, the global benchmark, fell $1.41, or 2.7%, to $50.54 a barrel on ICE Futures Europe. Prices rose 1.8% on the week.
The number of rigs drilling for oil in the U.S. rose by three this week, the second straight increase, Baker Hughes Inc. said Friday.
