The term deeply buried oil and gas reservoir was designated for particular oil and gas reservoirs that have a buried depth deeper than 4, m. From a geological point of view, this depth is equivalent to the special depth where liquid hydrocarbon was transformed into gaseous : Chengzao Jia.

A Carboniferous gas reservoir was discovered by well Xiang in eastern Sichuan Basin. May Xiangguosi Gas Field became operational.

A ring-shaped gas transportation trunk was built in the Sichuan Basin.

The Chuandongbei high sour gas field was discovered by well Luojia The Southwest Oil and Gas Field became the first. The natural gas in the eastern part of the Sichuan Basin, mainly produced from the Carboniferous Huanglong Formation, the Upper Permian Changxing Formation, the Lower Triassic Feixianguan Formation, as well as the Jialingjiang Formation generally Cited by: 1.

The eastern Sichuan folded thrust belt was shaped in the Yanshanian–Himalayan period, and fossil gas reservoirs were reconstructed to form a series of Carboniferous gas reservoirs, e.g.

the large Wolonghe and Datianchi Carboniferous gas fields, distributed in rows and belts in eastern Sichuan Basin. The karst dolomite reservoir, stratum residual area and limestone facies change area on the paleo erosion surface of Carboniferous in East Sichuan are superimposed with the current high and steep structures in Eastern Sichuan to form structure or structural-stratum (lithology) trap gas reservoir group Cited by: 6.

Other major gas fields in Sichuan are identified as Wulunghou, Shiyougou, Luzhou, Shendengshan, Zigong, Huanchiachan, Tengchingkuan, Huangkuanshan, and Yenkaohsi. Approximately oil- and gas-bearing structures have been discovered in Sichuan, with gas predominant in the south and oil in the center and east.

New research on basic geology has been done for Upper Carboniferous carbonate lithologic gas pools in the Huanglong Formation in the eastern Sichuan Basin. Based on the basement structure, sedimentary covers, and petroleum occurrence, the Sichuan Basin can be divided into four oil and gas accumulation districts (i.e.

The Jiaoshiba structure of Fuling shale gas field is a generally NE trending faulting anticline, and the main body is gentle while its margin is sandwiched by the faultsLocated at the Wan County Synclinorium in the high-steep fold belt of eastern part of Sichuan Basin, the Fuling gas field contains gas.

West Virginia today is mostly an erosional plateau carved up into steep ridges and narrow valleys, but million years ago, during the Carboniferous Period, it was part of a vast equatorial coastal swamp extending many hundreds of miles and barely rising above sea level.

This steamy, tropical quagmire served as the nursery for Earth's first primitive forests, comprised of giant lycopods. The Anyue gas field is a natural gas field located in Sichuan. It was discovered in and developed by and Sinopec. It began production in and produces natural gas and condensates. The total proven reserves of the Anyue gas field are around trillion cubic feet Country: China.

Research background As the major producing pay of gas field group in Sichuan Basin, Carboniferous reservoir is concentrated in high and steep structural belt of eastern Sichuan Basin, at the buried depths of 4 5 by: 3.

Therefore, by use of seismic and logging data from the high-steep complicated Carboniferous structure in eastern Sichuan Basin as a case study, a rock-electric model of the target drilling stratum. The Yuanba gas field is a natural gas field located in was discovered in and developed by and will begin production in and will produce natural gas and total proven reserves of the Yuanba gas field are around trillion cubic feet ( km³), and production is slated to be around million cubic feet/day (×10 5 m³).Country: China.

In recent years several H2S-rich oolite giant gas pools have been discovered in the Lower Triassic Feixianguan Formation of the northeastern Sichuan basin, and their explored gas reserves have been over × m3.

However, gas sources remain unsolved due to multiple source horizons with high maturity in this area and TSR alterations. By integrating analytical data of natural gas Cited by: Era, the Sichuan Movement gave rise to folded mountains around the basin and subsidence in the central part, forming the outline of the basin and leading to a massive deformation in the internal strata.

As a result, a set of northeast trending folds in the east (“Eastern Fold Belt”), a dome structure File Size: 7MB. Chunchun Xu's 10 research works with citations and reads, including: Status and prospects of deep oil and gas resources exploration and development onshore China.

Geological Characteristics and CO 2 Storage Capacity in the Huangcaoxia Gas Field Geological Characteristics. Huangcaoxia structure is a NE-trending anticline in which there are two structural high points along the eastern and western high altitudes, respectively (Figure 2(a)).The gas production strata are mainly located in the Lower Triassic Jialingjiang Formation (Jia-2 2 and Jia-2 1 Author: Hongwu Lei, Qian Zhang, Xiaochun Li.

Combined elemental and isotopic geochemistry of dolomites in the lower Cambrian Longwangmiao Formation, eastern Sichuan Basin with petrographic observations has been investigated to determine the origin of these dolomites.

Our data show that these dolomites are mostly located in the middle and upper parts of the Longwangmiao Formation, and most of them commonly occur as Cited by: 1. is located in the southeastern part of the Sichuan Basin and encompasses part of the high, steep structures of eastern Sichuan and the low-moderate structures in southern Sichuan, representing the most intensely deformed and folded region in the entireSichuan Basin (Fig.

Based on a comprehensive study of texture, diagenetic behavior and evolution of dolomite in the Huanglong Formation, trace (e.g., Fe, Mn and Sr) and rare earth element (REE) geochemistry, and isotopic characteristics (e.g., C, O and Sr), four types of diagenetic fluids are identified in the Huanglong Formation dolomite reservoirs of the Eastern Sichuan Basin, China: 1): marine Cited by: 9.

Previous research conducted in the central Ordos Basin, which shows high Ordovician relief, led to the discovery of the Jingbian gas field. 33 The terrain in the eastern part of the Jingbian gas field was speculated to be low according to the macrogeological background, 34 which meant that exploration and exploitation were generally not Cited by: 1.

Sichuan basin is the main gas producer of China. It covers an area ofkm{sup 2}. The evolution of this basin since Meso-Cenozoic was influenced by both trans-Eurasia Tethys tectonism from the west and the circum-Pacific tectonism from the east.
