The Research On Core Analysis Technology Of Du84Xing Ⅵ Block

It is a necessary method for core analysis to understand the geological characteris-tics of the reservoir, the sensitivity of the evaluation study, the mechanism of reservoir damage, comprehensive diagnosis of formation damage, reservoir protection technol-ogy solutions are designed to be built on the basis of core analysis above. Du84Xing Block VI heavy oil reservoir effective development requires in-depth understanding of reservoir characteristics, recognizing stratigraphic features such reservoirs, sedimenta-ry facies characteristics, features rock, rock debris particles and interstitial material characteristics, petrochemistry feature corre ondence between lithology and electrical characteristics, etc., caused by the exploitation of research SAGD oil reservoir proper-ties change, including changes before and after the heat and the potential role of miner-als due to the sensitivity of the reservoir.so, This needs for debris and mineral cements electron microprobe analysis, analysis of rock inclusions, rock major and trace element analysis of mineral morphology analysis and so on. The analysis is based on the expe-rimental understanding of SAGD hydrothermal rock mining process, the role of the ba-sic parameters of crude oil.For Du84Xing VI Block heavy oil reservoir coring wells samples were carried out electron microprobe analyzes of rocks and minerals; rock major elements, trace ele-ments, REE analysis; scanning electron microscopy and ectroscopy (morphology and mineral oxide minerals matter) analysis; X-diffraction whole rock and clay minerals (minerals) analysis; micro ancient plants (pollen, algae) analysis; NMR analysis and inclusions (salinity, composition and temperature) analysis. The purpose is to solve the VI Block Xing Du84heavy oil reservoir rock debris particles and interstitial material characteristics and other issues.A total of375test sample program, the actual test407.

Then the results obtained in preliminary studies, the conclusions drawn first step, more in-depth study for the next play down the foun-dation.These tests are the basis for determining the Du84Xing VI Block heavy oil reser-voir geological features, including the following a ects: The use of core data to carry out the reservoir four sexual relations, reservoir clas-sification and evaluation studies and reservoir types and reservoir heterogeneity re-search. Determine the physical parameters of favorable reservoir limit, analyze the main characteristics of favorable reservoir distribution reservoir sand bodies. Select all of reservoir evaluation parameters, and the reservoir layer, heterogeneity and its micro-planar phase analysis, reservoir quality assessment; determine the mechanism of di-agenetic evolution of mineral diagenesis evolution; determine reservoir mineral major elements, trace elements and REE composition; determine Du84Xing VI Block’s heavy oil reservoir into the reservoir formation, the formation temperature of times and understand the evolution of the reservoir.For Du84Xing VI Block, super heavy deep reservoir of ecial features to se-quence stratigraphy theory, from the core section coring analysis, combining the results of laboratory core analysis, logging data, seismic data, on-site production test results to identify the coring Inoue base level cycle, the Block identified a number of ways of combining layers of fine-grained comparison of ideas, in XingVI Blocks sandstone foundation Du84Xinglongtai oil division, the establishment of a84Du Xing Block VI reservoir stratigraphic framework, to ensure that the reservoir modeling longitudinal meshing accuracy.Based on the coring phase core observation and analysis of single well, combined with regional geological setting of the study area, the area come Xinglongtai Xing VI Block for underwater oil gravity flow fan depositional model; Xing VI Block for the lake shallow basin edge of the fan-delta deposition mode。Core analysis data measured as the main core analysis technique using a combina-tion of methods, combined with existing data, analyzed sedimentary Du84Xing VI Block reservoir with signs, establish the relationship between the particle size distribu-tion and sedimentary environment and paleontology。...
