The full extent of the models is based on Figure 2 . BXS – Baxian Sag; MXF – Maxi Fault; NDF – Niudong...

..., 2004 ). The Raoyang Sag developed as a subbasin in the Bohai Bay Basin of China, in which the Eocene Shahejie Formation is one of the major hydrocarbon reservoirs ( Zhao et al., 2010 ; Figure  1a and 1b ). Many detailed studies have been performed in the Eocene Shahejie Formation on the sequence...

... Movement. From the bottom up, the strata include the Changchengian system, Jixianian system, and Qingbaikouian system, which are mainly carbonate rocks interlaced with sandstones, shales, and chert bands and masses. Among them, Wumishan Formation is the most developed stratum, with the maximum drilling...

... of the optimal temperature. Next, we obtain the 3D distribution of thermal conductivity of deep formation in the Xiong’an New Area with the predicted temperature field. The distribution of terrestrial heat flow also is estimated. In addition, the law of thermal accumulation of strata at different depths...

... conditions—there are stratigraphic reservoirs rich in hydrocarbon. The lake basin in Raoyang depression declined while Dongying Formation was depositing, mainly with fluvial facies sediment in floodplains. Whereas the normal tension faults in the area east of Dawang Village, which controlled...

... and south Raoyang in the south, and the upper part of Kongdian Formation is gypsum-bearing; in the south is a set of gypsum-bearing salt and carbonate salt-lake mudstone. Sha3 dark mudstone is well developed in the east part. The north part is concentrated in middle and lower parts of Sha3 and is sedimented...

... speeds up the formation of flow channels, which further leads to the uneven decrease in the temperature of rock masses. As a result, fluids gradually concentrate in some dominant flow channels subject to thermal stress, thus causing rapid degradation of the heat production capacity of the reservoirs [ 19...

The analysis indicates that the depositional environment of the target lower part of the Ganchaigou Formation is an alluvial fan. We define eight lithofacies according to the core analysis and five sedimentary...

... interbedded with fine-grained sand. The section from 97.4 m to 183.8 m is known as the Raoyang Formation, which can be further divided into three members. Member 1 is a brownish yellow clay containing Mn and Ca nodules. The bottom of member 1 consists of fine- to medium-grained sand, in which tabular cross...
