层序地层学在松辽盆地地震勘探中的应用研究
|
摘要
以层序地层学理论为指导,提出了井震对比的一些原则和划分方案,在单井层序划分的基础上,以能在地震剖面上加以识别和追踪为原则,进行测井层序对比,建立研究区的测井层序格架,然后对目的层段做井震对比分析,不仅提高了地震层序划分的分辨率,也提高了地震解释的准确性和合理性。总结油气藏层序特征及规律,找出油气分布与层序体系域之间的内在联系和规律性,确定了有利含油气区带。采用测井约束波阻抗反演技术,进行了砂体分布预测,为研究区下一步勘探提供了依据。
Under the guidance of sequence stratigraphic theory,principles and division projects are proposed for well logging-seismic correlation.On the basis of single well sequence identification,logging sequence correlation is conducted with the principle of seismic profile recognition and tracking,a well logging sequence framework is established and logging-seismic correlation is made on target zones,by which the resolution of seismic sequence identification,the accurate and rationality of seismic interpretation are improved.By summarizing the characters and rules of reservoir sequences,finding out internal contact and rules of hydrocarbon distribution and sequence system domain,beneficial hydrocarbon zones are established.Sandbody distribution is predicted by using logging constrain wave impedance inversion,by which basis is provided for further exploration in the studied area.
