摘要
岩性序列定量地层划分对比是利用钻井岩性或综合柱状剖面进行地层划分和对比的一种数据处理方法 ,其中包括一重马链地层划分、倒频数法不等权滑动匹配 ,以及为了提高对比计算精度采用的多序列滑动对比、剖面拉伸和断点识别等。该方法不仅地质模型和数学模型正确 ,而且具有较高的实用推广价值 ,尤其在石油地质勘探和钻井数据库中实现井间自动对比方面拥有广阔的应用前景。
The quantative stratigraphic dividing and correlating by lithological successions is a data processing method to divide and correlate st rata by use of well lithology and comprehensive columnar sections.It includes th e one-step Markovian-chain stratigraphic division and the frequency number-re versed inequiweight sliding matching as well as the mutisuccession sliding corre lation,the section stretching and the break-point recognition who are used in o rder to raise the precision of correlation and calculation.This method not only has correct geologic and mathematical models,but also possesses higher practical and spreading values.It has wide prospects for application in realizing interwe ll automatic correlation between petroleum geologic exploration and well databas es.
