Volcanic Clastic Rock Of The Hailaer-Talmud Basin Logging Response Mechanism Of Petrology

Wu nan region of the Hailaer basin and nan bei er of the Talmud basin, are the our article main research blocks. Because they all have high potential of oil and gas exploration and development.They can serve as important succession of long-term oil and gas exploration in daqing oil field area, have very high research value.Due to the presence of pyroclastic rock, logging interpretation technology still has great difficulty in this aspect, mainly displays in three aspects, namely: the lithology identification, reservoir parameter calculating, fluid property recognition difficult. This directly led to the research area of oil-water layer integrated interpretation and oil production fluid of low coincidence rate. And in view of the Hailaer- Talmud basin fluid property identification difficult, for example, that might be the tuffaceous caused by the conductivity of the complex. Therefore the regional volcanic clastic rock lithology for experimental analysis.Therefore this article through to 12 Wells in the Hailaer- Talmud basin, the core data analysis, laboratory thin-section analysis, scanning electron microscopy(sem) analysis, electronic probe and X-ray diffraction analysis, etc. In combination with conventional logging data, on the Hailaer- Talmud basin main lithologic character description, the key research tuffaceous type, content, composition and occurrence state. Combined with X-ray diffraction data provided by the content of clay mineral information.Study the effect of clay mineral and gray matter of logging response coagulation.Finally, under the electron microprobe observation of tuffaceous bo crumbs it contains potassium, sodium, which possess the power to conduct electricity. Through scanning electron microscopy analysis at the same time, according to the results of tuffaceous itself late changes a lot, including clay minerals, the vitrified and silicide, also some influence of tuffaceous conductive properties. Quantitative research and qualitative conductive mechanism of clay minerals and gray matter coagulation, deepen the understanding of volcanic clastic rock lithology.
