APPLICATION OF SVR ATTRIBUTE FUSION CONSTRAINED BY GEOLOGICAL MODEL IN RESERVOIR DESCRIPTION OF SHALLOW WATER DELTA: A CASE STUDY OF X GAS FIELD IN XIHU SAG

X gas field is located in the central pinnoitettu kasari inversion structural belt of Xihu Sag, East China Sea Basin.The main target layer H4 is in shallow water delta sedimentary environment.The dominant frequency of seismic data of the gas field is low (25 Hz), while the buried depth of H4 layer is large (3 300-3 400 m).The reservoir has low poro

Worldwide research activity at the nanoscale is triggering the appearance of new, and frequently surprising, materials properties in which the increasing importance of surface and interface effects plays a fundamental role.This opens further possibilities in the development of new multifunctional materials with tuned physical properties that do not

ObjectivesThe vibration-isolation thrust bearing is a new device for the longitudinal vibration control of propulsion shafts.Experimental results show that the dynamic transmission characteristics of the propulsion shaft are quite different from those of theoretical calculation predictions.Analysis shows that there is serious vibration energy leaka
