层序地层学在油田开发中的应用突破了以往岩性地层对比的局限性，建立了一个高分辨率的年代地层格架，为油田开发建立更为可靠的地质模型提供了保证。通过典型井及过井地震剖面层序组合及体系域的划分，表明轮南油田JIV油组相当于层序1及层序2的低水位体系域，可划分为4个体系域、10个准层序、20个单层，并应用以上层序地层研究成果解决了轮南油田JIV油组的小层对比问题，验证了层序地层学方法在油田开发小层对比中的可行性。

This paper applies the sequence stratigraphy to the development of oilfields.The applation of this concept brokes through the
limitation of lithological correlation of stratigraphy in the past, and builts up a high-resolution formation frame, which generates a
relatively precise geological model for oilfield development. Based on the division of sequence associations and system tracts of
typical wells, the oil measures JIV of Lunnan Oilfield, analogous to the system tracts of low water level in sequence one and
sequence two, can be divided into four system tracts,ten parasequences and twenty single layers. At last this paper applies the
research result to the contrast and classification of oil measures JIV of Lunnan Oilfield, which proves the feasibility of the
application of sequence stratigraphy theory to the classification and correlation of thin layers during oilfield development.
