摘要

为对我国老油田后期挖潜、尤其是特高含水低效开发油藏的战略调整等提供新的思路,拓展老油田挖潜的领域与方向,以东营凹陷梁家楼油田沙三中纯47块高渗透大厚层高含水油藏为例,对其水淹特征与剩余油分布规律进行了综合研究。结果表明,该块油层水淹程度仅80%左右,剩余油在平面上分布于区块的绝大部分区域,且与构造高低无明显关系,纵向上主要集中于层段的上部,尤其是位于该块西北区构造低部位的北断层区潜力单元,是与目前老油田潜力区主要局限于正向型微构造区所不同的新类型与新领域。在此系统研究与总结基础上,提出并建立了高渗透大厚层油藏水驱与水淹模式图,同时提出了剩余油动态富集形成再生油藏的新观点,并建立了剩余油动态运移富集形成再生油藏的成藏模式。
In order to prvoide the new clue for the later tapping oil potential of maturing oilfiled,especially for the stratagem adjustment of high water-cut inefficient exploitation reservoir,and prolongate the realm and orientation of tapping oil potential,the waterflooding characteristics and the law of remaining oil distribution were studied.In case of Chun 47 block,high-permeability,big-thick-stratum and high water-cut massive reservoir in S_3 of Liangjialou Oilfield in Dongying depression,the study results indicate that the waterflooding degree of this region is only about 80 percent.The remaining oil distributes in the major region of the block that is obviously unconcerned with the high or low tectonic in plane direction and the super stratum in vertical direction.In particular,the north fault potential unit situated in the low position of northwest tectonic is the new type and new realm which is different from the potential confined mainly in the forward thin tectonic region.Based on the systematic study and summarization,the water-drive and waterflooding pattern drawings were brought forward and built for the high-permeability and big-thick-stratum reservoir. At the same time,the new standpoint was put forward that the remaining oil will concentrate dynamicly to form the renewable reservoir.And the corresponding mode of reservoir formation was established.
