Chang4+5 And Chang 6 Of Baota-Ganquan Area Reservoir Logging Evaluation

Papers in the study area is located in shaanxi province, between ganquan and rich county, belongs to the southeast of shanbei slope of ordos basin, the purpose of the research on the horizon is Triassic extended leader 6 reservoir to 2 reservoir long group, focus on the long 4+ 5 and chang 6 reservoir.Paper based on the actual production of oil field, a large collection of logging data, logging data, analysis, test and test report and other data, through to the existing log data processing, and with modern interpretation of modern reservoir description theory as the guidance, using the theory and technology such as well logging geology, reservoir geology method, concrete from core analysis, comprehensive utilization of well drilling, well logging, testing, pre-production, production performance data, focus on using new well coring, testing, test data, focuses on study of key Wells "four sex" relationship, determine the reservoir chart, "four sex" relationship between oil and water layer interpretation chart, determine the lower limit of effective layer standards; On this basis for comprehensive evaluation of reservoir.This paper established four sexual interpretation chart, it is concluded that the area of oil and water layer electrical identification and lower limit of effective thickness standards, to improve the interpretation coincidence rate of oil and gas water, for an explanation of adjacent structure oil and gas water has important guiding significance. To reinterpret the log data, this paper through the lithology, physical property, oil-bearing and electricity sex research as well as logging interpretation model to be reliable basis to calculate oil reserves in the region. In the division of logging curve to identify reservoir and effective thickness plays an important role. Through long district 4+5, and 6 in the area of reservoir logging evaluation, evaluation and the basis to the next step the production of oil and gas exploration and development production, provides a strong basis.
