英语翻译
water production begins first in wells completed low in the strucutre because the water,in its displacing action on oil,arrives at these wells first.water production in these wells increases continuously until the wells must be abandoned because oil production is insufficient to economically justify their continued operation.A much larger portion of oil originall in the reservoir is recovered by energy andaction of a water drive than by either dissolved-gas drive or gas-cap drive.such recovery normally will be approximately 35 to 75 per cent of original oil in place

感觉你这篇短文中间某些单词可能打漏了或者打错了,不是很通顺.尝试翻译如下：
水的产生首先发生在已完工的,而结构上处于较低位置的油井,这是由于水会首先到达这些（位置较低的）油井,而且水有驱油的作用.这些油井中的产水量会持续增大,直到油井由于石油产量不足,无法在经济上保证其持续运作而被弃用.
通过（使用）能源与（采取）行动,水驱能够被溶解气驱或气顶驱动所取代,更大的部分的原有油储量能够被采收,这种采收通常是占了地层中原有油量的约35％到75％.
