1983年,济阳坳陷新探明了石油地质储量二亿吨。进入1984年,又传出喜讯,在孤北地区的奥陶系古潜山中,打出了一口会战以来最好的高产井,日产原油3600多吨和天然气36万立方米,令人鼓舞。新储量主要分布在以下三种地区:一是盆地的边缘,如单家寺—尚店西—林樊家地区,从沙四段到东营—馆陶组多层含油,从内向外含油地层逐层抬高,不同层系在空间可以连片。二是在盆地的低洼部位也找到相当可观的石油,它们以梁家楼、牛庄、六户地区为代表,石油主要储藏在巨厚生油岩系内席状、带状或透镜状砂体中,油层的压力高、产量高。第三类发现于各二级构造带的端部和鞍
In 1983, Jiyang Depression proved new oil geological reserves of 200 million tons. In 1984, another good news came out that it was encouraging to see that the best high-yield wells in the Ordovician burial hills in the Gubei area have produced over 3,600 tons of crude oil and 360,000 cubic meters of natural gas each day. The new reserves are mainly distributed in the following three areas: one is the margin of the basin, such as the Shanjiashan-Shangdianxi-Linfanjia area, the multi-layer oil from the Es4 Member to the Dongying-Guantao Formation, and the oil-bearing strata from the inside to the outside Layers raised, different layers in the space can be contiguous. Second, considerable oil has also been found in the low-lying parts of the basin. They are represented by Liangjialou, Niuzhuang and Riuzu areas. The oil is mainly stored in the matted, banded or lenticular sand bodies of the giant thick oil-bearing rock series , The reservoir pressure is high, the output is high. The third category was found at the ends and saddles of each secondary structural belt
