Unlike Wells designed to pump crude, oil sands don't have the same production decline rate.

因为钻探原油的油井产量是递减的，但含油砂却没有这种产量递减率。

Analysis of production decline rate is an important item in development planning of oil -gas fields.

油气田产量递减率分析是开发规划中的一项重要内容。

After implementation, initial production of oil Wells has risen 83.4% on the average, and production decline rate is reduced greatly.

措施实施后油井初产平均提高83.4%，且产量递减率大大降低。

This reflects investment patterns, the rate of production decline and, above all, a guess at prices, which is notoriously hard to do.
