摘要
大庆喇嘛甸油田开发的目的层主要为萨尔图、萄花油和高台子油层,断层边部的厚油层顶部属于低水淹层,存在剩余油。利用水平井可扩大泄油面积、提高油层动用程度,且水平段能够穿越夹层,可以实现挖潜断层边部剩余油的目的。应用开发地震技术,结合钻井、测井、试油、沉积相等资抖,通过细致描绘喇嘛甸油田萨Ⅲ31层的顶面构造特征,预洲萨Ⅲ31层的分布形态、厚度和展布范围,可为水平井设计提供了可靠的地质依据。
The main development layers of Daqing Lamadian oilfield are Salto,Putaohua and Gaotaizi oil reservoirs,the the top of thick reservoirs at the edge of faults is lowly waterflooded,exist remaining oil.Application of horizontal wells may enlarge drainable area,increase the degree of producting performance of reserviors,and produce the horizontal section cross interbeds,it can realize potential tapping of remaining oil at the edge of faults.Application production seismology,in conjunction with data of well drilling,well logs ,testing and sedimentary facies,through detailed depiction of top structural characteristics of SⅢ31 reservoir in Daqing Lamadian oilfield,predicting distribution shape,thickness and distribution range of SⅢ31 reservoirs,it provides reliable geological basis for design of horizontal wells.
