摘要
小油砂体因其储量规模小、钻遇率低、井网控制难度大、动用难度大、开发效益差,未能引起足够重视。随着老区开发难度的增加,有效合理开发小油砂体,使其成为经济可采储量,形成接替产能日显重要。通过对零散分布小油砂体水驱控制程度及最小含油面积与井网的匹配关系研究,得到了零散分布小油砂体理论水驱控制程度以及最小油砂体面积与注采井距的计算方法,为零散分布小油砂体油藏开发方案的制定和调整提供了理论基础和依据。
Due to the small reserves,low drilling success rate,difficult for well pattern control and producing,as well as poor benefit,enough attention was not paid on small oil sandbodies.With the increase of difficulty of old oilfield development,it became more and more important for rational and effective development of the small oil sandbodies.Through the study of water flooding control level of the stray distribution of small oil sandbody and the matching of minimum oil area with the well pattern,the calculation method was obtained for theoretical waterflooding control level of the stray distribution of small oil sandbody and the minimum oil sand area from the injection-producing well spacing.It provides the theoretical basis for setting up and adjustment of the program of stray distribution of small oil sandbody reservoirs.
