Controlling Factors of Overpressure Formation in the Yinggehai Basin

Energy Exploration and Exploitation, 2012
There are many previous studies on the formation mechanism of overpressure in sedimentary basins. The Yinggehai Basin is a typical strike-slip extensional basin with obvious overpressure phenomenon. Yinggehai Formation begins to appear overpressure in Central Diapir Zone with the depth of less than 2000 m. Undercompacted, hydrocarbon generation are the

Overpressure Identification and Pressure Prediction in Yinggehai Basin

International Journal of Geosciences, 2019
The accurate prediction of overpressure is one of the key issues that restrict the effective development of oil and gas resources in the Yinggehai Basin. In this paper, the formation mechanism of overpressure in Yinggehai Basin is studied. Based on this mechanism, the quantitative prediction model and empirical parameters of overpressure are optimized ...

Mechanism of Enhanced Gas Recovery and Carbon Storage Capacity in Gas Reservoirs With CO2 Injection: An Example of Dongfang Gas Field

Engineering Reports
China's Yinggehai Basin gas field is in the middle and late stages of development and has a large CO2 sequestration potential. Moreover, the gas recovery is low, and it can be further enhanced by injecting CO2. In order to study the recovery ratio of the

Geochemical Characteristics of Natural Gas in the Yinggehai-Qiongdongnan Basin, South China Sea

Energy Exploration and Exploitation, 2010
Geochemical characteristics of natural gas in the Yinggehai-Qiongdongnan Basin were studied and analyzed based on gas component properties and carbon isotopic characteristics which were tested and collected of more than 100 samples. The gas in the Yinggehai-Qiongdongnan Basin was generally alkane gas, and all the area showed dry gas characteristics ...
