子长油田中山川区长6剩余油潜力研究

Residual oil potential of chang 6 in zhongshanchuan area of zichang oilfield

以子长油田单井控制地质储量分布为基础,充分利用研究区现有开发动态资料,运用水驱曲线法对子长油田中山川油区主力层长6进行了采收率标定,确定单井控制可采储量,通过对研究区剩余油分布的研究,明确其中富集量和规模大的有长612,较大的有长611、长613,较小的有、长621、长622,为该区长6油层调整挖潜提供依据。

Based on the distribution of c ontrolled geological reserves of single well in Zichang Oilfield, this paper makes full use of the existing development dynamic data in the research area, and uses the water drive curve method to calibrate the recovery ratio of the main reservoir of Chang 6 in Zhongshanchuan Oil Region in Zichang Oilfield to determine the controlled recoverable reserves of single well.Through the study on the distribution of remaining oil in the study area, it is clear that the enrichment and scale of Chang 612 and Chang 613 are large, followed by Chang 611 and Chang 613, and the enrichment and scale of Chang 621 and Chang 622 are the smallest, providing the basis for adjusting and tapping the potential of Chang 6 oil layer in the study area.
