这里收集了十四个平均单井日产量在千吨以上(或接近千吨)的油田的资料,从这些油田的资料可以看出以下问题:一、碳酸盐油田具有高产的条件,应该加以重视。在收集到的十四个油田中,有十一个是碳酸盐油田。除少数水驱活跃外,其余都是边水不活跃或气顶驱动,平均渗透率也不太高。国外在开发这些油田时的做法,首先是充分利用天然能量,例如伊朗。有的碳酸盐油田开发了三十年以后才着手保持地层压力,但采油速度都比较低。

Fourteen data on the average daily production of singletons above 1,000 tons (or nearly one thousand tons) are collected here. From the data of these fields, we can see the following questions: First, carbonate oil fields have high yield conditions and should be added Pay attention. Eleven of the fourteen fields collected are carbonate fields. Except for a few water-driven activities, the rest are side-water-inactive or gas-capped and the average permeability is not too high. In the overseas development of these fields, the first step is to make full use of natural energy, such as Iran. Some carbonate fields have been under development for about 30 years before they began to maintain formation pressure, but their production rates are relatively low.
