摘要:泰国湾区域经历了前裂谷期、裂谷期、裂后期的构造演化阶段,形成了多个裂谷盆地。泰国湾区域东北部在渐新世经历了一次明显构造反转,较泰国湾区域大部分地区强烈。通过对比区内钻井,结合地震解释,对该区的沉积特征和构造演化进行了略论,认为这次反转构造导致了反转构造带上构造、沉积特征与邻区有较大的不同。由于这次反转构造,泰语论文范文,泰国湾东北部在新层系发育新类型的油气系统,即深部的始新统油气系统烃源岩为中始新统湖相泥岩,泰语论文范文,储层为上始新统一渐新统三角洲相砂岩,盖层为下中新统三角洲前缘相泥岩和上中新统以上的海相泥岩。该油气成藏系统已被钻井钻遇油气显示,是本区有效油气成藏系统。 Abstract:The Thailand Bay area has experienced the stages of pre rift, rift and post rift tectonic evolution. The Thailand Bay area northeast experienced an obvious tectonic inversion in the Oligocene, most areas of Thailand Bay area strong. Through the comparison of drilling, combining with the seismic interpretation, the sedimentary characteristics and tectonic evolution are analyzed, that the tectonic inversion resulted in tectonic inversion zone structure, sedimentary characteristics and its adjacent areas are quite different. Due to the inversion tectonics, the Northeast Gulf of Thailand in the new series of strata and development of new types of oil and gas system, namely deep beginning new system of oil gas system of hydrocarbon source rocks started Miocene lacustrine mudstone, reservoir for beginning a new unity gradually Miocene delta facies sandstone, cover layer for the lower Miocene delta mudstone and upper above the Miocene marine mudstone. The oil and gas reservoir forming system has been drilled in the case of oil and gas, and it is an effective oil and gas reservoir forming system in this area. 引言:1引言泰国湾区域是东南亚地区著名的油气富集区,区内发育马来盆地、北大年盆地等大型富油气盆地[1],具有优越的油气地质条件和油气资源勘探前景。由于泰国湾区域基底埋深较深,地层沉积厚度巨厚,所以现阶段油气勘探除钻探前第三系潜山构造外,勘探层位均在渐新统及更新统地层,始 |
