Abstract

Although various geochemical and geophysical investigations have already indicated a great resource potential in the Xisha area of the South China Sea, the origin of organic matter and molecular evidence for tracing the migration of hydrocarbons from deep petroleum reservoirs are still lacking. In this study, systematic organic geochemical analyses, including bulk organic matter parameters and lipid biomarkers were performed for deep sediments from two cores. The C/N ratios and δC and δN values of organic matter in most of the samples, together with the maxima of short-chain -alkanoic acids and mid-chain -alkanols, high abundances of monounsaturated fatty acids C and C, jointly indicate the dominance of marine organic matter. -Alkanes in sediments from core GMGS4-XH-W06B are characterized by small unresolved complex mixture (UCMs) humps, high odd/even predominance (OEP) and carbon preference index (CPI) values, clearly exhibiting characteristics of modern sediments. However, the sediments for core GMGS4-XH-W03B are featured with big UCMs, associated with OEP and CPI values around 1.0, showing signatures of petroleum hydrocarbons from high maturity sources. Considering the geologic background, the biomarker signatures are solid evidence for indicating the existence of underlying petroleum reservoirs, and may provide the valuable information for assessing the hydrocarbon resources in the Xisha area.

摘要

尽管各种地球化学和地球物理调查已经表明南海西沙地区具有巨大的资源潜力，但有机物质的来源和追踪深油藏中碳氢化合物运移的分子证据仍然缺乏。在这项研究中，对两个岩芯的深部沉积物进行了系统的有机地球化学分析，包括有机质参数和脂质生物标志物。大多数样品的 C/N 比、δC 和 δN 值以及短链 -烷酸和中链 -烷醇的最大值，共同表明了海洋有机质的主导地位。GMGS4-XH-W06B 岩芯沉积物中的 -烷烃的特点是小未解析复杂混合物 (UCM) 峰，高奇偶优势 (OEP) 和碳优先指数 (CPI) 值，明显表现出现代沉积物的特征。然而，GMGS4-XH-W03B 岩芯的沉积物具有大的 UCMs，与 OEP 和 CPI 值约为 1.0 相关，显示出源自高成熟源的石油碳氢化合物的特征。考虑到地质背景，生物标志物特征是存在底层石油储层的有力证据，并可能为评估西沙地区的碳氢资源提供有价值的信息。
