| 摘 要： | 地层的精细划分与对比是油气勘探研究的基础工作，地层划分的好坏直接影响着油气勘探后续的研究。在收集大量的地质资料基础上，以鄂尔多斯盆地姬塬油田主要生油层——延长组长2油层组为研究目的，在全区内寻找分布比较稳定的主要标志层K9和长2底砂岩以及K7辅助标志层，将延长组长2油层组地层划分为3个小层。本研究为该地区的开发提供可靠的依据，并为下一步大规模开发建产作好了技术储备。

| Abstract: | The fine division and contrast of stratum is the basic work of oil and gas exploration, and the following research of oil and gas exploration is affected by the division of the stratum directly. Based on a large number of geological data, the main petroleum source bed - extended 2 oil group at Jiyuan Oilfield in Ordos Basin is studied. K9 marker bed which is steady distribution and extended 2 lower sandstone and K7 supplementary marker bed in the whole region were discovered. Reference to the rule of gyration, thickness, and electrical characteristics of rocks, the extended 2 oil group were divided into small layers of 2 - 1,2 - 2 and 2 - 3. This provides basis for the development of extended 2 blocks and the reliable technical reserves for the next large - scale development and instruction. |
