【摘要】：以泌阳凹陷南部陡坡带梨树凹地区为例,利用研究区丰富的录井、测井、岩心、分析化验、地震资料,从构造特征、沉积相、油藏精细解剖入手,开展了东部砂体沉积特征与成藏模式研究。研究表明:梨树凹地区主要发育近岸水下扇,具备较好的油气成藏条件,油气成藏主要受烃源岩条件、沉积相带与构造因素的控制;近岸水下扇油藏有2种成藏模式,一种是深层扇根物性封堵、扇中油气聚集的物性封堵型成藏模式;另一种是浅层鼻状构造与扇中砂体配置形成构造+物性控制型成藏模式。近岸水下扇油藏是泌阳凹陷下步油气勘探的重要领域。该研究对泌阳凹陷小型砂砾岩体后续勘探有一定的指导意义。
[Abstract]:Taking the Lish sag area in the southern steep slope of Biyang sag as an example, the abundant mud logging, logging, core analysis, analysis and seismic data are used in the study area, starting with structural characteristics, sedimentary facies and fine anatomy of the reservoir. The sedimentary characteristics and reservoir forming model of sand bodies in the east of China were studied. The results show that there are mainly nearshore subaqueous fans in Lishuwa area, which have good oil and gas accumulation conditions, and are mainly controlled by source rock conditions, sedimentary facies zones and structural factors, and there are two types of reservoir formation models in near-shore underwater fan reservoirs. One is the physical plugging model of the deep fan root, the other is the shallow nose structure and the sand body configuration in the fan to form the reservoir forming model of the structure and physical property controlling the accumulation of oil and gas in the fan and the other is the shallow nose structure and the configuration of the sand body in the fan. Near-shore underwater fan reservoir is an important field of next step oil and gas exploration in Biyang sag. This study has certain guiding significance for the follow-up exploration of small sand and gravel rock in Biyang sag.
