目的解决研究区小层划分对比上的问题。方法借鉴油藏数值模拟中的有限差分网格方法,利用测井资料提出油田开发中一种新的实用性较强的地层划分对比方法——有限差分网格方法。结果在层序地层和沉积旋回控制的基础上,重新标定出了研究区的小层对比统一标志,找出了一系列辅助标志层。结论研究结果对指导沉积矿产资源勘查,层序地层划分具有指导意义。
Aim To solve the problem of contrasting and dividing the small area in the study area. The method draws lessons from finite difference grid method in reservoir numerical simulation and uses logging data to propose a new and practical method of stratigraphic division and contrast - finite difference grid method in oilfield development. Results On the basis of sequence stratigraphy and sedimentary cycle control, the uniform sign of small-scale contrast in the study area was recalculated and a series of auxiliary sign layers were found out. Conclusion The results of the study are instructive to guide the exploration of sedimentary mineral resources and the stratigraphic division.
