摘要:
辽东走滑断层转换带东营组油田具有储量规模大、丰度高的特点，但该类油藏形成条件尚不明确. 利用钻井、三维地震、测井以及分析化验等资料对辽东湾拗陷辽东走滑带旅大A油田的油藏特征及油气综合成藏条件进行了研究. 结果表明该油田含油层系是古近系东营组，具有含油层段集中、储量丰度高的特点，是一个整装优质古近系油田. 烃源岩厚度大，有机质丰度高、成熟度适中、类型好，为高丰度油田提供了充足的物质基础. 辽中1号走滑断层转换带控制形成断背斜圈闭，东营组发育辫状河三角洲沉积形成巨厚储层，以及辽中1号走滑断层内部诱导裂缝带形成高效油气运移通道，共同构成了良好的成藏条件，是高丰度油田形成的保障. 东营组发育一期油气充注，具有晚期快速充注的特征，是高丰度油田形成的前提.
Abstract:The oilfield of Dongying Formation in Liaodong strike-slip fault transfer zone is characterized by large reserves and high abundance. However, the forming conditions of such reservoirs remain unclear. This study investigates the reservoir characteristics and comprehensive hydrocarbon accumulation conditions of Lyuda-A oilfield in Liaodong strike-slip zone of Liaodong Bay Depression by using drilling, 3D seismic, well logging and analytical test data. The results indicate that the oil-bearing series is the Paleogene Dongying Formation, belonging to an integrated high-quality Paleogene oilfield with the characteristics of concentrated oil-bearing intervals and high reserves abundance. The source rocks with large thickness, high abundance of organic matter, moderate maturity and favorable types provide sufficient material basis for the high-abundance oilfield. The faulted anticlinal trap controlled by the LZ1 strike-slip fault transfer zone, the thick reservoir formed by braided river delta developed in Dongying Formation and the efficient hydrocarbon migration pathway formed by induced fracture zones within the LZ1 strike-slip fault collectively constitute favorable accumulation conditions, ensuring the formation of high-abundance oilfield. The first-stage oil-gas charging in Dongying Formation is characterized by the late-stage rapid charging, which serves as a prerequisite for the formation of high-abundance oilfield.
