Study on the simulation of acoustic logging measurements in horizontal and deviated wells被引量：7
《Applied Geophysics》2017年第3期337-350,459,共15页刘鹤 王兵 陶果 张阔 岳文正 
supported by National Natural Science Foundation of China(No.41204094);Science Foundation of China University of Petroleum,Beijing(No.2462015YQ0506)
The conventional acoustic logging interpretation method, which is based on vertical wells that penetrate isotropic formations, is not suitable for horizontal and deviated wells penetrating anisotropic formations. This...

Application of 3D stereotomography to the deep-sea data acquired in the South China Sea:a tomography inversion case被引量：2
《Applied Geophysics》2017年第1期142-153,191,192,共14页邢逢源 杨锴 薛冬 汪小将 陈宝书 
funded by China Natural Science Foundation(Nos.41574098 and 41630964);China key specialized project(No.2016ZX05026-001-03)
A 3D stereotomography algorithm, which is derived from the 3D Cartesian coordinate, is applied for the first time to the deep-sea data acquired in the LH area, South China Sea, to invert a macro velocity model for pre...

Tomographic inversion for microseismic source parameters in mining被引量：5
《Applied Geophysics》2012年第3期341-348,362,共9页缪华祥 姜福兴 宋雪娟 杨淑华 焦俊如 
supported jointly by projects of the National Natural Science Fund Project(No.51174016);the National Key Basic Research and Development Plan 973(No.2010CB226803)
We propose a new method for inverting source function of microseismic event induced in mining. The observed data from microseismic monitoring during mining are represented by a wave equation in a spherical coordinate ...

Studies on phase and group velocities from acoustic logging被引量：5
《Applied Geophysics》2012年第1期108-113,117,共7页王晶 陈德华 张海澜 张秀梅 何晓 王秀明 
supported by the National Natural Science Foundation of China (Grant No. 40774099, 10874202 and 11134011);National 863 Program of China (Grant No. 2008AA06Z205)
It is still argued whether we measure phase or group velocities using acoustic logging tools. In this paper, three kinds of models are used to investigate this problem by theoretical analyses and numerical simulations...

Matrix porosity calculation in volcanic and dolomite reservoirs and its application被引量：8
《Applied Geophysics》2009年第3期287-298,301,共13页Li Ning Wu Hongliang Feng Qingfu Wang Kewen Shi Yujiang Li Qingfeng Luo Xinping 
sponsored by the Science Research and Technology Development Project of Petrochina Company Limited "Well Logging Interpretation and Integrative Evaluation of the Complex Lithology"(Grant No.2008A-2705)
Matrix porosity calculations of fractured and vuggy reservoirs, such as volcanics and weathered dolomite, are one of the problems urgently needed to solve in well-log evaluation. In this paper, we first compare the an...

Adaptive Spatial-division Split-step Fourier Migration Method
《Applied Geophysics》2005年第2期75-79,i0001,共6页赵景霞 张叔伦 王昌龙 倪逸 
This paper presents a new depth migration method, adaptive spatial-division split-step Fourier （ASDSSF） migration. In this method we introduce the idea of a stratified phase shift migration into the split-step Fouri...
