摘要
冀中地区滚动勘探开发实践证明,要在复杂断块区进一步提高勘探精度和勘探效益、实现老区增储上产,关键在于根据不同地质条件选择应用变速成图技术。高分辨率及全三维地震资料目标精细处理技术、复杂断块构造精细解释技术和低电阻油层识别技术。这些关键技术对于精细描述潜山顶面构造形态、提高潜山和断块勘探精度、发现新的含油层系能够起到十分重要的作用。冀中地区应用这些技术,“九五”前三年仅在老油田内部就新增石油地质储量2000×104t以上,同步建成产能超过40×104t。图4(梁星如摘)
This paper, based on the actual geological conditions for petroleum exploration and development in Jizhong, diseusses the importance of progressive exploration and development in improving the accuracy and benefits of petroleum exploration in complicated fault blocks.Based on different geologic conditions, the author mainly proposes the key techniques, i. e. use of changeable velocities for time-depth conversion, process of high resolution and three dimension seismic data, interpretation of complicated fault blocks and identification of oil-bearing formations of low resistivity, etc.. The key techniques are of great significance fOr improving exploration acctiracy and benefits in mature areas, that is, raserves increment and producibility improvement. Good economic effects have been achieved through actual application of these techniques in the mature areas.
