Abstract (183) PDF (306KB)(6)
Abstract:
Sedimentary slopes of the Bohai Gulf basin may be divided into three types and four kinds according to their structures,and four kinds of corresponding sedimentary sequences are distinguished.The sand bodies may be divided into eight types of reservoir according to the sedimentary facies,with the fl...
DISTRIBUTION AND CONSTRAINTS OF BURIED HILL RESERVOIRS IN THE JIYANG DEPRESSION,BOHAI GULF BASIN

2006, 12(1): 31-36.
Abstract (223) PDF (269KB)(9)
Abstract:
Buried hill reservoirs in the Jiyang depression have complex types and are widespread,and structural fractures are the main oil accumulation space of buried hill reservoirs.The distribution of buried hill reservoirs in the Jiyang depression is mainly controlled by the process of basin formation.Tect...
DISTRIBUTING CHARACTERISTICS OF FLUID PRESSURE IN THE ZHANHUA SUBBASIN, JIYANG DEPRESSION,BOHAI GULF BASIN, AND THEIR INFLUENCE ON OIL AND GAS ACCUMULATIONS
LI Sheng-li, YU Xing-he, CHEN Jian-yang, FENG Dong-jun, WANG Yong-shi
2006, 12(1): 37-42.
Abstract (207) PDF (236KB)(6)
Abstract:
Six types of fluid pressure are distinguished on the basis of integrating measured data and theoretical calculation.Normal pressure is dominant in oil and gas accumulations in the Zhanhua subbasin,but high abnormal-pressure oil and gas accumulations exist in strata at depth.In a plan view,high abnor...
MESO-CENOZOIC EVOLUTION OF THE TANLU FAULT AND FORMATION AND DISTRIBUTION OF PETROLIFEROUS BASINS
YANG Zhan-bao
2006, 12(1): 43-48,70.
Abstract (249) PDF (298KB)(15)
Abstract:
A number of Meso-Cenozoic medium and large petroliferous basins in the peri-Pacific region in the eastern part of continental China are distributed on both sides of or inside the Tanlu fault.It is evident that the formation and evolution and distribution of these petroliferous basins are related to ...
GRAVITY GRADIENT INVERSION OF DEEP STRUCTURE IN THE SOUTHWEST SEA BASIN
TANG Ren-min, ZHANG Jian
2006, 12(1): 49-54.
Abstract (173) PDF (356KB)(10)
Abstract:
The gravity gradient anomaly reflects the change of gravity anomaly,and it has a higher resolution than gravity anomaly.The plot of gravity gradient space parameters can give diagnostic information of dip angles and planes.A geometric model of subsurface structure may be constructed by integrating a...
CHARACTERISTICS AND ORIGIN OF TRANSVERSE ACCOMMODATION ZONES IN THE DONGPU SUBBASIN,BOHAI GULF BASIN, AND THEIR ROLE IN REGIONAL SEGMENTATION
SUN Si-min, PENG Shi-mi, HUANG Shu-wang
2006, 12(1): 55-63.
Abstract (223) PDF (422KB)(9)
Abstract:
Through an analysis of the distribution of vertical displacements along the strike of the boundary faults in the Dongpu subbasin in various phases,the authors deduce the growth process of these faults.He thinks that the complex fault system originated from connection of individual fault segments dur...

LIU Wen-ye
2006, 12(1): 64-70.
Abstract (276) PDF (276KB)(11)
Abstract:
The author introduces the basic principle and procedure of wavelet analysis and discusses the applicability of the log signal wavelet analysis in the high-resolution sequence stratigraphic division.The cycles of various orders may be obtained after multi-scale wavelet resolution of log signals.He ma...
NEW TEST METHODS FOR PARAMETERS OF INDIVIDUAL PAY ZONES IN A MULTI-ZONE RESERVOIR: RESEARCH AND PRACTICE
ZHAO Zhong-jian, HE Zhi-xiang, LI Zhi-ping
2006, 12(1): 71-76.
Abstract (258) PDF (187KB)(6)
Abstract:
Conventional pressure buildup/drawdown tests of wells have disadvantages such as long test time,influence on well production and difficulty in obtaining parameters of individual pay zones.In regard to these disadvantages,the authors propose two multi-zone well test methods,i.e.the variable flow rate...
