基于地震资料双域同步分析的沉积期次划分方法应用研究
|
摘要
对三角洲、砂砾岩体等复杂地层结构而言,常规的沉积期次划分手段主要是利用测井资料进行分析,井与井之间横向对比难,由点及面外推不确定性强,且无法直接获得空间上对沉积特征的认识。为了解决上述问题,特别是针对钻井数目少的勘探新区,采用了基于地震资料双域分析的方法,即时深域与Wheeler域同步分析法进行沉积期次划分,给出了方法的具体实施步骤及分析过程。应用该方法将东营三角洲沙三段中亚段地层划分了9个期次,建立了目的层段地层精细的等时格架。生产实践表明,应用该方法进行期次划分的结果符合三角洲沉积规律,与实际钻井揭示的岩性分布特征吻合程度高。
For complex stratum structure such as delta and sand-gravel bodies,conventional sedimentary sequences classification method using logging data often leads to difficulty in lateral contrast between wells and strong uncertainty extrapolation from point to plane,therefore the recognition of sedimentary characteristics in space cannot be directly obtained.In order to solve the problem,especially for the new exploration area with few drilling wells,we carry out sedimentary sequences classification in double-domain based on seismic data that is to carry out synchronous analysis in time-depth domain and Wheeler-domain.The detail realization steps and analysis procedure are displayed.By using this method,we divide the middle Es3 strata into nine sedimentary cycles and stages in Dongying Delta system and establish fine isochronal stratigraphic framework.Field production practice proves that the classification result is coinciding with the delta sedimentary rules and the actual lithology distribution revealed by drilling.
