Sedimentary characteristics and reservoir origin of the mound and shoal microfacies of the Ma51+2 submember of the Majiagou Formation in the Jingbian area

Journal of Petroleum Science and Engineering, 2021
Abstract The carbonate rocks of the Majiagou Formation contain extensive oil and gas resources. To determine the rock type, sedimentary characteristics and sedimentary environment of the Ma51 + 2 submember, its sedimentary microfacies are distinguished via core observation, thin section analysis, scanning electron microscopy and cathodoluminescence ...

The Research and Application of a New Interpretation Chart—Taking the Ordovician Majiagou Formation in the Eastern Ordos Basin as an Example

Springer Series in Geomechanics and Geoengineering, 2021
The weathering crust reservoir in the upper ordovician majiagou formation in the eastern ordos basin have been focused as a desert of exploration in recent years. As a result of uplift in Caledonian, reservoir spaces such as fractures and pores in the majiagou formation in the eastern part of the basin were mostly filled and destroyed, all above cause ...

Characteristics of Karstification in the Penecontemporaneous Period in Majiagou Formation, Ordovician, Sulige Gas Field

open access: yes, 2021
Sulige gas field is the major gas-production area in Ordos Basin. The carbonate of the Ordovician Majiagou formation is one of the most important target-strata for gas exploration. The karstification in the penecontemporaneous period has a significant constructive effect on the reservoir development of Majiagou formation, which is the most important ...

Petrographic, rare earth elements and isotope constraints on the dolomite origin of Ordovician Majiagou Formation (Jizhong Depression, North China)

Marine and Petroleum Geology, 2020
Abstract Dolomites from the Ordovician Majiagou Formation are considered as major hydrocarbon reservoir rocks in the Yangshuiwu area, Jizhong Depression. However, the origin of the dolomites remains unclear. This study utilizes a composite analysis of seawater-normalized rare earth elements (REEs), petrography and isotopes (C, O and Sr) to trace ...

Optimal selection of favorable areas for CO2 geological storage in the Majiagou Formation in the Ordos Basin

International Journal of Greenhouse Gas Control, 2021
Abstract Carbon dioxide (CO2) geological storage (CGS) is considered as one of the feasible choices for large-scale CO2 emission reduction worldwide, and the primary issue in CGS is how to select areas favorable for storing CO2. The research conducted by Chinese scholars on CO2 geological storage in the Ordos Basin has mainly focused on numerical ...
