摘要
东营凹陷博兴洼陷新生界下第三系沙河街地层沙二段油藏具有规模小、埋藏浅、单井产能高、难以发现等特点,属于典型小而肥的油藏。通过对博兴洼陷沙二段沉积体系研究和储层精细刻画,发现沙二段发育大量三角洲前缘砂体,在正理庄地区逐层上倾尖灭形成多套岩性油藏。运用多种物探技术描述出多个"朵叶体",在这些"朵叶体"高部位部署的多口滚动勘探井均获得了高产油流,实现了沙二段构造--岩性油藏的滚动勘探新突破,探索出一套沙二段构造—岩性油藏的勘探技术和认识,为在其它地区开展类似油藏勘探提供了借鉴。
The second member of the Shahejie formation of the Lower Tertiary Shahejie Formation in the Boxing sag in the Dongying Sag has the characteristics of small scale,shallow burial,high single-well productivity,and difficulty in finding.It is a typical small and fat reservoir.Through the study of the sedimentary system of the second member of the Shahejie Formation in the Boxing Sag and detailed characterization of the reservoir,it is found that a large number of delta front sand bodies are developed in the second member of the Shahejie Formation,and they have been dug out layer by layer to form multiple sets of lithologic reservoirs.Multiple geophysical prospecting techniques were used to describe multiple"lobed bodies",and multiple rolling exploration wells deployed in the high parts of these"lobed bodies"all achieved high oil production flow and realized the second member of the Shahejie Formation--lithologic reservoirs.A new breakthrough in rolling exploration has explored a set of exploration techniques and knowledge for the second member of the Shahejie Formation-lithologic reservoir,which provides a reference for similar reservoir exploration in other areas.
