Main controlling factors and development model of the Miocene marine source rocks in Yinggehai Basin

地质科技通报, 2021
The Miocene marine source rock is the main oil and gas supplier of the Yinggehai Basin and the typical representative of the Cenozoic marine source rocks in China.Based on comprehensive analysis of geological, geochemical and paleontological data and the

Porosity prediction by geophysics technology at low-porosity and low-permeability reservoir of the Yinggehai Basin

地质科技通报, 2022
The moderate deep and deeplayers of the Ledong area in the Yinggehai Basin is regarded as the main districts in recent exploration. The reservoirs in L10 zone are generally characterized by low-porosity and low-permeability, suggesting that the high ...

A New Methodology Combining Geophysical Calculations and Geological Analysis to Identify and Characterize Carrier Systems for Vertical Hydrocarbon Migration in the Central Diapir Zone of the Yinggehai Basin, China

Energies, 2023
To understand hydrocarbon migration in terms of the mechanisms, accumulations and exploration targets, it is essential to correctly identify and characterize the carrier systems that control fluid-migration history and oil/gas reservoir formation.

Moho Inversion by Gravity Anomalies in the South China Sea: Updates and Improved Iteration of the Parker‐Oldenburg Algorithm

Earth and Space Science, Volume 10, Issue 9, September 2023., 2023
Abstract The Moho is the interface between crust and mantle, and accurate location of the Moho is important for both resource exploration and deep earth condition and structural change investigations. The theory of the traditional Parker‐Oldenburg (P‐O) method is quite simple and it is widely applied in the frequency domain of Moho depth inversion ...

Identification and Prediction of Allo-Source Overpressure Caused by Vertical Transfer: Example from an HTHP Gas Reservoir in the Ledong Slope in the Yinggehai Basin

Geofluids, 2021
The Yinggehai Basin is a typical high temperature and high pressure (HTHP) gas-bearing basin. The pressure coefficient exceeds 2.2 in deeply-buried Miocene reservoirs in the Ledong Slope, a nondiapir zone in the Yinggehai Basin.

Discrete Element Modeling of Southeast Asia's 3D Lithospheric Deformation During the Indian Collision

Journal of Geophysical Research: Solid Earth, Volume 128, Issue 1, January 2023., 2023
Abstract The Indian collision has deformed the eastern Asian continent in a multifaceted way, uplifting Tibet and surrounding mountains, activating ≥1,000 km‐long strike‐slip faults, and opening Tertiary rifts and oceanic basins up to ≈3,000 km away from the Himalayas. Modeling such broad‐scale tectonics has been challenging.

Source Rock Evaluation of Hydrocarbons in Deep‐Water Offshore Areas Based on a BP Neural Network

Geofluids, Volume 2023, Issue 1, 2023., 2023
Due to the lack of drilling data and poor quality of seismic data in deep‐water offshore areas, conventional methods cannot effectively predict the total organic carbon (TOC) content. In this paper, the BP neural network method is used to predict the TOC of the strata overlying the target layer, which adds to the TOC information in the study area. Then,

A Method of Inverting Rock Grain Size Based on Nuclear Magnetic Resonance Logging Data and Application

Geofluids, Volume 2023, Issue 1, 2023., 2023
Rock grain size parameter is the key parameter of reservoir rock physics analysis. The study found that the relationship between the NMRT2spectrum and rock grain size distribution curve is directly related to NMRT2distribution and grain size distribution of rock, so you can use T2 to retrieve the size distribution of rock NMR spectral data.

Natural Gas Migration Pathways and Their Influence on Gas Hydrate Enrichment in the Qiongdongnan Basin, South China Sea

Geofluids, Volume 2022, Issue 1, 2022., 2022
2D and 3D seismic data and basin simulation were used to investigate the gas hydrate distribution and natural gas migration pathways in the Qiongdongnan Basin (QDNB). Hydrate‐related amplitude anomalies and extensive bottom simulating reflectors (BSRs) were mapped within the uppermost part.
