摘要
大庆外围地区扶杨油层探明储量占大庆外围地区累计探明储量一半以上。扶杨油层河道砂体规模小,储层物性差,非均质性强。通过分析扶杨油层加密调整区块开发效果和开展未开发储量评价,提出了扶杨油层储量注水开发优选界限和建立有效驱动体系井排距界限,研究形成了“两个界限”以上Ⅰ,Ⅱ类储量井网与压裂整体优化设计方法,在肇源油田源35等区块注水开发见到了明显效果。此外,探索了Ⅲ类储量采用特殊结构井、非常规方式开发的可行性。
The proved reserve of Fuyang oil layer, with small-scale channel sand body, poor physical property and serious heterogeneity, accounts for more than 50 percent of accumulative proved reserve in outlying pools of Daqing Oilfield. By analyzing development effect of infill-regulate block and estimating undeveloped reserves, this paper determines the waterflood development optimal limit for Fuyang oil layer reserves and the well line spacing limit of effective drive system, prescribes types I and II reserves well pattern according to the “two limits” and integral optimization procedure for fracturing, by which obvious effect has been observed in the process of waterflood development in Yuan35 Block, etc. in Zhaoyuan oilfield. In addition, the feasibility of adopting special structure well and unconventional development plan to type III reserves was discussed in this paper.
