摘要/Abstract

摘要：

受低油价影响,SD油田高效滚动开发难度越来越大。为进一步挖掘SD油田滚动潜力,扩大SD周边圈闭成果,通过采用：①精细构造解释,识别低序级断层;②加强基础地质研究,深化油气成藏主控因素认识;③部署开发兼评井,提高单井利用率;④动静结合,滚动扩大老区含油面积;⑤上下层系立体评价,降低滚动勘探风险等方法,使得SD油田在“十二五”至“十三五”期间新增含油层系2个、含油断块6个,新增探明储量1.011×10⁷ t,有力支持了华东原油持续上产工作,并且建立了SD油田成藏模式,明确戴一段隐蔽油藏与火成岩相关油藏是今后滚动勘探的重点方向。

Abstract:

SD Oilfield’s progressive exploration and development is getting more and more difficult under low oil price. In order to tap its potential and extend the peripheral trap results, by the means such as: ①fine structural interpretation to identification of low sequence faults, ②strengthen the basic geological researches to deepen the understanding of the main control factors of oil and gas reservoir formation, ③deploy the development and evaluation of wells to improve utilization of single wells, ④combined dynamic and static analyses to rolling expand the oil-bearing area of old area, ⑤comprehensive evaluation of upper and lower layers to reduce the risk of the progressive exploration, two oil-bearing layers and six oil-bearing fault blocks have been added in SD Oilfield during the period from the 12th Five-Year Plan to the 13th Five-Year Plan and the newly added proved reserves are 1 011×10⁴ t, which strongly support the persistent increase of oil production in Sinopec East China Oil and Gas Company and establish the accumulation mode of SD Oilfield. It is clear that the key direction of the progressive exploration are the subsurface reservoir and igneous related reservoir of Daiyi Formation in the future.

Key words: SD Oilfield, composed progressive exploration and development, fine structure research, study on sedimentary microfacies, accumulation mode, volcanic rocks reserve
