巴伦梯油田是法国第一大油田,面积25平方公里,地质储量6880万吨。油田于1954年投产。巴伦梯油田是非均质程度比较严重的裂缝性白云岩油田,水驱比较活跃,但各层的水驱活跃程度也很不均衡。油田于1957年开始注水。巴伦梯油田早期注水遇到了选择注水方式、调整各层间水面均匀推进等一系列问题。油田投产20年后,截止1974年共采出原油2190万吨,占地质储量的31.8%,已接近开采初期预计的可采储量2322万吨的数值,油田平均年采油速度1.51%(按地质储量计)。
Barron ladder is France’s largest oil field, an area of 25 square kilometers, geological reserves of 68.8 million tons. Oilfield put into operation in 1954. The Balunti oilfield is a fractured dolomite oilfield with serious heterogeneity. Water flooding is relatively active, but waterflooding activity at various levels is also very uneven. Oilfield began to inject water in 1957. In the early stage of Balinti oilfield, a series of problems were encountered, such as choosing the water injection method and adjusting the uniform water surface between the various layers. Twenty years after the oilfield was put into operation, a total of 21.9 million tons of crude oil were recovered by the end of 1974, accounting for 31.8% of the total geological reserves, which is close to the expected recoverable reserves of 23.22 million tons at the initial stage of mining. The average annual oil recovery rate is 1.51% meter).
