Research And Application On The Reifning Description Measures Of Meandering Single Sandbodies

Nowadays the Daqing Oilfield has entered its later high water-cut stage, and thewell pattern also become very dense. Based on the material of the core and welllogging, the Daqing placanticline fluvial facies sedimentary mode has been deeplyacknowledged by researching such five architecture hierarchies as sedimentary Units,sedimentary facies, single meandering belt, single point bar and lateral accretionbodies. Through the studies of the lateral accretion interlayer's scale and model ofmeander sand body, the four important parameter of lateral accretion interlayerincluding dip direction, dip angel, expanded range and horizontal range weredescribed, and a new refining interpretation method has been established. And theaccuracy rate of interlayers logging interpretationhas been lifted. This paper provide arelatively mature reservoir modeling method of the fluvial facies, realizes theconnection of the intraformational model building and numerical simulation. Thispaper's research acknowledgments have got some effectiveness from the fieldapplication, and can be generally applied in the future.
