TRANSMAGMATIC FLUID THEORY AND OREFIELD STRUCTURE
HEI Hui-xin, LUO Zhao-hua, Vikentyev I V, GUO Jing
2015, (1): 1-12.
Abstract (224) HTML (151) PDF (949KB)(21)
Abstract:
A new understanding of the ore-field structure is proposed. According to the theory of metallogeny by transmagmatic fluid (TMF), it is emphasized that the ore-field structure system is a complexity dynamic system. Based on this model, the ore-field structure deformation is resulted by strong interac...

2015, 21(1): 30-37.
Abstract (276) HTML (157) PDF (1095KB)(49)
Abstract:
Based on the finite element method, numerical simulation on the state of present stress in Bozhong 25-1 oilfield which is the first low permeability oilfield carried out to be developed by CNOOC is studied. Combined with the geological characteristics, the impact of the stress on development is anal...

Abstract (248) HTML (122) PDF (1046KB)(24)
Abstract:
Based on the research on development of structural fractures that controlled by reverse fault, this study has simulated the distribution of the stress, strain and the development rules of fractures under the different conditions of horizontal forces, lithological characters, fault dip and the differ...
THRUST\STRIKE-SLIP-FAULT BELT STRUCTURES EVOLUTION CHARACTERISTICS AND PHYSICAL MODELING OF ZAIRE MOUNTAIN
WANG He-hua, WU Kong-you, PEI Yang-wen, GUO Wen-jiang, LIU Bo
2015, 21(1): 56-65.
Abstract (361) HTML (170) PDF (1347KB)(29)
Abstract:
As the exploration direction transfers to orogenic belt in the northwestern margin of Junggar Basin, the thrust belt of Zaire Mountain has become the exploration focus. Previously, the thrust belt is thought to be typical over-thrust and nappe belt, but the fault space composition relationships on t...
RESEARCH ON CORE FRACTURES: A CASE STUDY FROM THE FUTAI OILFIELD
