Abstract The Cathaysian Coastal Mountains are thought to be an ancient high‐topographic feature that existed along the margin of South China. They characterised by extensive Jurassic–Cretaceous magmatism; however, their formation mechanism and timing remains uncertain. In this paper, we present sedimentological detrital zircon analyses from Cretaceous–Eocene strata drainage sediments Hainan Island. Our show a change in provenance proximal arc source Cretaceous widely distributed intra‐island...
Fracture weaknesses are two important parameters to describe the characteristics of reservoir fracture-induced anisotropy. Accurate estimation for fracture is great significance seismic exploration and characterization naturally fractured reservoir, especially gas-bearing reservoir. Linear inversion based on Bayesian theory can fuse prior information. And inverse problem solved in form posterior probability density function (PDF) obtain maximum solution. Based PP-wave reflection coefficient...
The lack of an initial condition is one the major challenges in full-wave-equation depth extrapolation. This vertical partial derivative surface wavefield and cannot be provided by conventional seismic acquisition system. traditional solution to use value calculate assuming that velocity constant. However, for exploration on land, often not uniform. To solve this problem, we propose a new method calculating from without making any assumptions about conditions. Based calculated derivative,...
Abstract Because of the high drilling expense and fewer wells having been drilled in Deepwater Pearl River Basin, complexity difficulty oil gas exploration this area always restrict our development procedure. In order to overcome these problems exploration, paper will propose a comprehensive feasiable approach, which makes full use both well logging data seisimic combine techniques rock physical modelling seismic pre-stack inversion. Such well-orgnised technical system searching is conducive...
The tuned liquid dampers (TLD) technology is a feasible and cost-effective seismic design. In order to improve its efficiency it fundamental find accurate models describing their dynamic. A TLD system can be modeled through the Housner model parameters estimated by solving nonlinear state estimation problem. We propose robust extended Kalman filter which alleviates discretization fact that noise process not known. test effectiveness of proposed approach using some experimental data...
