A New Method for Determining the Spatial Distribution Law of Rock Anti-Drilling Characteristics

Shiyou jixie, 2021
When the existing method for determining the distribution laws of rock anti-drilling characteristics is adopted, the rock anti-drilling characteristics at the same depth are not distributed continuously and the spatial distribution laws of rock anti ...

The Selection of Reasonable Pore‐Throat Cutting Factor for Shrinkage Pore Network Extraction in Sandy Conglomerate Reservoir

International Journal of Energy Research, Volume 2025, Issue 1, 2025.
The sandy conglomerate reservoir exhibits substantial vertical extent and considerable thickness, which provides significant capacity for CO2 storage. Meanwhile, the shrinkage pores are developed in the tuff‐filled material of sand conglomerate reservoir, which is not only the oil/gas storage space, but also the ideal fluid flow channel of CO2.

Deep‐Buried Triassic Oil‐Source Correlation in the Central Junggar Basin, NW China

Geofluids, Volume 2017, Issue 1, 2017., 2017
Whether there is an effective deep‐buried lacustrine Triassic petroleum system in the Junggar Basin, NW China, has been enigmatic and debated for a long time. Here we conduct an oil‐source correlation to address this issue. Results show that the extracted bitumens from the Triassic mudstones in the central basin have distinctive stable carbon isotope ...

Multimethod Prediction of Pore Pressure in the Deep Jurassic System of the Central Junggar Basin

Geofluids, Volume 2025, Issue 1, 2025.
Drilling has shown that there is significant overpressure throughout the Jurassic in the central Junggar Basin and that the maximum pressure coefficient exceeds 2.0. The pore pressure in the central Junggar Basin was jointly predicted by combining a number of methods, such as the Eaton, Bowers, and equilibrium depth methods based on logging data, with ...

Numerical Simulation Study on Optimization of Multiparameter Combination for Horizontal Well Fracturing in Nonhomogeneous Conglomerate Reservoirs

Geofluids, Volume 2025, Issue 1, 2025.
Optimizing multicluster fracturing designs in heterogeneous conglomerate reservoirs is critical due to their complex characteristics. This study employs the continuous–discontinuous element method (CDEM) to conduct engineering‐scale 3D simulations using a mathematical model incorporating rock strength heterogeneity.

Experimental Study on Pore Structure Quantitative Characterization and Enhanced Oil Recovery During Air/CO2 Flooding of Shale Reservoir With Online NMR

Geofluids, Volume 2025, Issue 1, 2025.
Injecting air or CO2 into shale reservoirs can significantly enhance oil recovery (EOR) following the initial depletion. However, effectively characterizing the complex pore structure of shale reservoirs poses a challenge, leading to an incomplete understanding of the seepage mechanism and microscopic production characteristics of air/CO2 flooding at ...
