南黄海海相油气勘探前景探讨与问题分析

南黄海海域的中、古生代海相油气前景广阔，是重要的油气战略接替基地。由于多期构造运动的改造作用，原型盆地遭受强烈破坏，地质构造复杂，地球物理勘探精度低，造成对地层与构造认识不清，油气分布规律不明。针对勘探中面临的主要问题，提出的主要对策是：重点开展地球物理勘探技术创新研究与攻关试验工作，提高方法技术的适用性与有效性；在大地构造理论的指导下，重点开展多期构造活动背景下有效烃源岩、储层、保存条件等因素的研究工作，对区域油气地质条件优越且地层、岩性等特征存在争议的局部构造实施科学钻探等。

Marine Oil and Gas Exploration Prospects,Problem and Strategies in South Yellow Sea

The Mesozoic and Paleozoic marine oil and gas have broad oil and gas prospects in South Yellow Sea, and are important strategic replacement bases for oil and gas. Due to the transformation of multi period tectonic movement, the original basin was destroyed severely. The geological structure is complex, the precision of geophysical prospecting is low, the structure and formation are unavailable, and the oil and gas distribution is unknown. In view of the main problems faced in the exploration, the main strategy we suggested is to focus on the research of geophysical exploration technology innovation and test work, and then to improve the applicability and effectiveness of the method and technology; under the guidance of the geotectonic theory to carry out the research works for hydrocarbon source rock,reservoir and oil gas preservation conditions based on the background of multi-period tectonic movement; to implement scientific drilling in local structural areas where the regional petroleum geological conditions are superior and the characteristics of strata and lithology are controversial.
