摘要： 春光油田新近系沙湾组以曲流河沉积为主，河道不断迁移改道，砂体叠合频繁，井网密度小，单一河道边界识别困难，局部井区油水关系矛盾大，限制了单砂体剩余油的进一步挖潜。为精细刻画研究区单一河道边界，达到油气精细开发的目的，以测井响应特征为基础，总结了单一河道边界4种典型标志；建立初始地质模型，通过地震正演，总结地震识别标志，为稀井区单一河道的识别提供技术方法；依据地层切片上砂泥岩响应特征，在平面上识别出不同时期单一河道的展布特征和发育位置。井震联合方法克服了测井资料横向上预测的不确定性，提高了单一河道的刻画精度。

Abstract: The sedimentary system of the Neogene Shawan formation in Chunguang oilfield is dominated by meandering river deposits. Due to the continuous river channel migration and diversion, frequent vertical superposition of sand bodies and sparse well pattern, it is hard to identify the boundary of a single channel. Besides, the oil-water relationship is contradictory in some wellblocks, which limits the further remaining oil potential tapping. To detailedly characterize the single channel boundaries and achieve the goal of fine oil and gas development and on the basis of logging responses, the paper concludes four typical indicators to depict the boundary of single channel, establishes an original geological model and summarizes seismic identification indicators. According to the responses of sandstone and mudstone on the strata slices, the distribution characteristics and development positions of single channels of different periods are identified. The logging-seismic combination method can overcome the uncertainty of lateral logging data prediction and improve the accuracy of single channel characterization.Keywords:
