In the series,by taking the objective oriented large comprehensive database as the basis,the computer technique as the means,and the processing and interpretation techniques of seismic formation lithology as the core,the organic combination of multiple disciplines as geology,well logging and seismics and the processing interpretation integration under the same geological objective are realized.
From biostratigraphic classification of drill and outcrop, specially like Lengke 1 well, and based on theory of stratigraphic sequence, the authors trace and identify seismic formation of the Jurassic stratum in North of Qaidam Basin, research seismic facies and sedimentary facies of Jurassic stratum and discuss the characteristics of hydrocarbon source rocks and reservoirs in stratigraphic framework.
The seismic formation inversion that is restricted by multiple boreholes improves usual description of compact nonuniform gas reservoir in west Sichuan basin.
Application and Effects of Well Logging Constraint Seismic Formation Inversion in the Progressive Exploration and Development——A Case of Exploration and Development of the Third Member of Shahejie Formation in Dongxin lithologic Pinchout
Therefore we can find that the isotopic geochemistry is gradually playing an important role in studying the seismic formation mechanism and in seismic monitoring and prediction.
Based on these characteristics and wavelet derived from target bed for seismic data body, the corresponding relationship between seismic formation near well and log horizon was adjusted, synthetic record was made, and horizons were marked.
In the fields of experiments and theory, many developments are obtained in cause of seismic formation, condition of stress and tectonics, dynamics of earthquake rupture, rock fracture and nucleation of strong earthquakes.
This paper deduces the accurate solutions of stress field produced by vertical point force in semi-infinite elastic bodies,which are regarded as nuclei for integral calculation.Distributive characters of additional stress in crust caused hy vertical force sources with different parameters are studied.The conclusious are used to analyse the causes of seismic formation in the region of North China.
Studying at the quake-active area on the isotopic chronology of K-Ar, Ar-Ar, FT, FL, 14C, ESR, U series of the relating geological body, the underground water and the stable isotopes of D/H, 13C/12C, 18O/18O by its released gases, and the isotopes of the rare gases of He and Ar, we can obtain many important informations concerning the time sequence of the neotectonic movement, the time of the fault movement, the thermal history of the geological body and the fluid movement of underground fault. Therefore we...
The gas bearing sand bodies in the Upper Paleozoic in Eerduosi Basin belong to the distributary channel deposits of lake delta plain,being of the properties of low porosity,low permeability and high impedance.In accordance with such a geological objective,4 categories(15 items)of the methods and techniques were developed and summarized,and the processing and interpretation technical series of the gas bearing sand body comprehensive prediction objectives in the Upper Paleozoic in Eerduosi Basin were set up...
