Terrestrial Lacustrine Turbidite Reservoir Characteristics And Description Of Methods - In Dongying Depression, For Example,

China is a petrobleum-production country mainly possess terrestrial petroliferous basin, in the depocenter of the terrestrial petroliferous basin, the sandstone lithologic oil pools that the primary reservoirs are variouskinds of turbibite sand bodies and have large amount of reserves distribute widely, and this is a chief character of the terrestrial petroliferous basin.For the special concealment of the turbidite sand bodies ,it isvery difficult to predict and describe the tubidite reservoirs. So, the study of the depositional character of the turbidites and the descriptive methods of the turbidite oil reservoirs has important real-life signifcance in the exploration development of the trubidite oil reserviors.This paper takes example for the Shinanregion in the cental uplift of the Dongying depression,made a thorough study on the form conditions and the depositional character of the turbidite sand bodies, carried through a detailed analysis and summarize around the tubidite depositional rule, reservoir character, source direction, reservoir physical parameters, etc. The regional basic geology model and microfacies model were established,and the sand bodies faciesbelte were confirmed correctly. The junction of the seismic and the geology were established through the basic geophysical work, mainly includes mensurating the coer rock elastic parameters by the expeiments,polar analy the seismic profite, establishing the velocity model,enhancing the execution quality of compound seismic log,so that the demarcate tally rate of the reservoir layers can be increased obviously.The log-restricted inversion technology were ameliorated either, the tog seismic and geology were comected so that form the forecast methods and technology of thin layer sandstone body log restricted.Through the study of log evaluation methods,especially the analysis of the form mechanism of low-resistance oil reservoir and the tag interpretation, the reserves calculation of single turbidite sandstone body realized,the calulative precisicn of the reserve parameters increased,achieved the mational petroleum criteria. This study has formed a fine descriptive method about the turbidite sandstone body,much improved the ration descriptions of the sandstone body, and acquired distinct effects and benefits in the progressive exploration and development of the turbidite oil reservoirs in research area...
