WASHINGTON, Sept 8 (Reuters) - The U.S. government on Wednesday slightly raised its forecast for growth in world oil demand this year, but cut the forecast for next year on the gloomy outlook for strong global economic expansion.

In its latest monthly forecast, the U.S. Energy Information Administration raised its estimate of growth in 2010 world oil consumption by 50,000 barrels per day, projecting a demand increase of 1.62 million bpd this year to 85.95 million bpd.

The rise was due mostly to strong demand from China, the Middle East, and Brazil.

But a poor outlook for demand in developed countries weighed on the forecast for next year.

The EIA cut its 2011 forecast by 100,000 bpd, now projecting a rise of 1.41 million bpd to 87.36 million bpd.

"The economy is still struggling and that does not bode well for oil demand," said Phil Flynn, an analyst at PFGBest Research in Chicago.
