Hydrocarbon Potential of Pre-cenozoic Strata in the North Yellow Sea Basin

The North Yellow Sea Basin ( NYSB ), which was developed on the basement of North China (Huabei) continental block, is a typical continental Mesozoic Cenozoic sedimentary basin in the sea area. Its Mesozoic basin is a residual basin, below which there is probably a larger Paleozoic sedimentary basin. The North Yellow Sea Basin comprises four sags and three uplifts. Of them, the eastern sag is a Mesozoic Cenozoic sedimentary sag in NYSB and has the biggest sediment thickness; the current Korean drilling wells are concentrated in the eastern sag. This sag is comparatively rich in oil and gas resources and thus has a relatively good petroleum prospect in the sea. The central sag has also accommodated thick Mesozoic-Cenozoic sediments. The latest research results show that there are three series of hydrocarbon source rocks in the North Yellow Sea Basin, namely, black shales of the Paleogene, Jurassic and Cretaceous. The principal hydrocarbon source rocks in NYSB are the Mesozoic black shale. According to the drilling data of Korea, the black shales of the Paleogene, Jurassic and Cretaceous have all come up to the standards of good and mature source rocks. The NYSB owns an intact system of oil generation, reservoir and capping rocks that can help hydrocarbon to form in the basin and thus it has the great potential of oil and gas. The vertical distribution of the hydrocarbon resources is mainly considered to be in the Cretaceous and then in the Jurassic.

黄海海域前第三系及油气勘探

黄海位于西太平洋构造域，由中朝地块和扬子地块及其相邻的褶皱带构成，印支运动以来，形成了前第三系克拉通，裂陷和走滑-拉分等叠合的残留盆地，研究认为，黄海前第三系及其残留盆地评价要解决两个关键问题：其一，确定残留盆地的分布及其边界；其二，在恢复原型盆地（包括剥蚀量的恢复）的前提下，进行盆地埋藏史，成烃聚集史的成藏动力学和含油气系统分析，然后进行前第三系的评价勘探，以提高油气勘探的成功率。     

基于GIS数据仓库的激光单分子海洋油气化探数据可视化处理

采用基于地理信息系统(GIS)的数据仓库技术,以激光单分子海洋油气化探数据处理与评价作为数据仓库主题,实现了激光单分子海洋油气化探数据的可视化处理。将可视化处理分为4个步骤:数据预处理、异常背景分析、异常分析、异常综合评价;使用MAPX、DELPHI等软件研制开发了相应的可视化软件模块。通过对渤海湾盆地某测区实测的甲苯化探数据的处理,验证了所开发技术的实用性。     

雷州半岛探油论

雷州半岛与南海北部大陆架相连，为第三系分布区，与北部湾及珠江口盆地都是南海北部大陆架上的第三纪盆地。上第三系从北部湾经雷州半岛至珠江口盆地是一片相连的海相沉积，雷州半岛在第四纪才露出海面成为半岛。根据地质特征分析，雷州半岛是南海北部大陆架的一部分，地层、构造相连，含油气前景相同。北部湾及珠江口盆地巳找到并开发了十多个油田，年产石油1000万t。预测雷州半岛乌石凹陷西部能找到海陆相连的有商业价值的油田。     

南海北缘东部盆地油气资源研究

南海北缘东部的珠江口盆地及台西南盆地蕴藏着十分丰富的油气资源，根据区域构造背景、盆地发育分布的特点及中、新生代的油气地质条件，结合含油气构造、油气田、油气井的分布规律，利用油气资源评价的理论、方法，对区内的油气资源进行了综合研究，并按照油气资源状况划分出油气富集区、油气潜力区、油气远景区，在此基础上，再进一步划分出4条油气富集带、11条油气潜力带、8条油气远景带，充分显示了该区石油、天然气的分布规律和油气地质特点，为商业性的勘探开发和理论研究奠定了基础。
