Zhenjiang is also a famous city in the Southern Song Dynasty, where the story of Liang Hongyu, an outstanding female heroine, "Liang Hongyu beat Jinshan" happened. Xin Qiji, a patriotic poet in the Southern Song Dynasty, guarded Zhenjiang in his later years. When he went to the Gushan Pavilion in the north, he wrote the first paragraph of the famous sentence "Nanxiangzi: Inherent Love in the North of Dengjingkou" with great emotion: "Where can I see China?" The striking epigram of "Feng Guang Gu Bei Building".
Where to see China? Where can I find oil? In order to ensure the success of the oil battle in northern Jiangsu, the command post moved to Jiangbei, stationed in Yangzhou, and had a day-and-night command dialogue with the construction site.
Yangzhou, known as "the capital of Huaizuo", is one of the four famous cities in ancient China. "The spring breeze travels ten miles along Yangzhou Road, so it is better to roll a bead curtain" and "The street hangs a thousand steps to reflect the twin cities" are all good sentences describing the bustling city scene of Yangzhou at that time.
Yangzhou was founded in the thirty-fourth year of the Spring and Autumn Period (436 BC). At that time, under the rule of King Fu Cha, the kingdom of Wu in the south gradually became stronger, sending troops to cut Qi, and the north conquered the Central Plains and built a city of Han. From the late Warring States to the Qin Dynasty, it was called Guangling City, and the Sui Dynasty officially named Yangzhou. With Luoyang as the center, the canal dug by Emperor Yang Di is about 1 000 kilometers long from Luoyang to Huaiyin, which is called Yongji Canal, and it is about 1 000 kilometers long from Luoyang to Zhuo Jun County, Hebei Province (now southwest of Beijing), and then it is about 400 kilometers long from Zhenjiang to Hangzhou. Yangzhou is the hometown of President Jiang Zemin. He likes the poem of Du Mu, a poet in the Tang Dynasty: "There is water in the green hills, but grass in the south of the Yangtze River has not withered in autumn. On the moonlit night of the 24th Bridge, where can jade people teach flute playing? " It is said that this poem is similar to Mozart's piano concerto No.23 in artistic conception.
I visited Yangzhou Pingshan Hall (Jian Zhen Monk Memorial Hall) to see the Yangtze River and the south of the Yangtze River. Recalling Du Mu's poem "The grass in the south of the Yangtze River is not withered in autumn" is a great feeling to visit its territory! Upp team is located at the exit of Qiaoqu in Hanjiang City.
Cui Zhendong, commander of Jiangsu Petroleum Exploration Command, led the oil battle in northern Jiangsu with two right-hand men, geophysicist Xu and petroleum geologist Yang Pu.
Subei basin covers an area of about 32,000 square kilometers. As a continental sedimentary basin based on Indosinian-Yanshan fold belt, it began to accept basin deposition in Cretaceous, and the Tertiary period was the main period of depression development, with the maximum thickness exceeding 6000 meters.
The basin consists of two depressions, namely Dongtai Depression and Yanfu Depression, and Jianhu Uplift between them. A series of convex and concave structures are formed in the depression, which are arranged in the northeast direction. Dongtai sag is the main body and sedimentary center of the basin, which is divided into four depressions: Jinhu, Gaoyou, Qintong and Hai 'an from west to east. The basin extends northeast and connects with the South Yellow Sea, so it is often called Subei-South Yellow Sea Basin.
Tertiary experienced two tectonic movements: Wubao movement at the end of Eocene and Tripod movement between Neogene and Paleogene. Two periods of tectonic movement played a regional control role in basin structure and evolution.
Tertiary sedimentation can be divided into three main stages: Eocene Funing Formation has a maximum thickness of 2,000 ~ 2,500 m and an average sedimentation rate of 0. 1mm/ year, which is the main oil-bearing series in northern Jiangsu, with good oil-generating conditions and good source-reservoir-cap assemblage; The maximum sedimentary thickness of Oligocene Dai Nan Formation and Sanduo Formation is over 2000m, and the reservoir conditions are good. The maximum sedimentary thickness of Neogene Yancheng Formation is about1700m, and the sedimentary rate is between 0.08 and 0.16mm/year.
Faults are the main structural units in Subei Basin. They not only control the boundary and sedimentary distribution of positive and negative structural units, forming the development between a half-graben fault depression and a fault uplift, but also control the generation of local structures and the migration and storage of oil and gas, especially oil and gas reservoirs dominated by fault blocks.
After the command post arrived in northern Jiangsu, the drilling teams from Wupu and Liu Pu were mainly engaged in Qintong sag at first, and then gradually turned to Gaoyou and Jinhu sag.
