小龙湾地区位于辽河盆地东部凹陷热河台油气田东南侧，属于翘倾断块复式油气聚集带。在对该区构造演化史、沉积史深入研究的基础上，建立了成藏模式。分析认为，受烃源条件、圈闭条件的控制，在该区内不同部位发育了岩性圈闭、构造—岩性圈闭、不整合面圈闭、古潜山圈闭、披覆背斜圈闭等。据此，分别对翘倾断块低部位的上倾方向、下倾方向，以及翘倾高部位进行了储层预测。今后的勘探重点应放在Ｅｓ３构造—岩性圈闭和Ｅｓ１岩性尖灭圈闭上，并兼顾对古潜山和披覆圈闭的勘探。
Located in the southeastern side of the Rehetai oil and gas field in the eastern sag of the Liaohe Basin, the Little Bay area belongs to the overthrust block multi-stage hydrocarbon accumulation zone. Based on the deep research on tectonic evolution and sedimentary history of the area, a reservoir forming model was established. According to the analysis, under the control of hydrocarbon source conditions and traps, lithologic traps, tectonic-lithologic traps, unconformity trap, buried hill trap, drape anticline are developed in different parts of the area Trap and so on. Based on this, the reservoir prediction was made on the up-dip direction, down-dip direction, Future exploration should focus on the Es3 structure - lithologic traps and Es1 lithic pinnacle trap, and take into account the exploration of buried hills and drape enclaves.
