The Pearl River Mouth Basin, which is situated on the northern margin of the South China Sea, has attracted great attention not only because of its tectonic setting but also because of its abundant hydrocarbon resources. We have analyzed the Cenozoic tectonic subsidence history of 4 drilled wells and 43 artificial wells from the zhu 1 Sub-basin of the Pearl River Mouth Basin by back-stripping, using newly interpreted seismic profiles. We also calculated the average tectonic sub- sidence rates of the four sags in the zhu 1 Sub-basin. The rifting and post-rifting stages are separated by abrupt changes in the tectonic subsidence curves and average subsidence rates. In the eastem sags of the zhu 1 Sub- basin, tectonic subsidence started to slow at ca. 30 Ma, compared with ca. 23.8 Ma in the western sags. This probably corresponds to the timing of break-up and suggests that tiffing in the Pearl River Mouth Basin ended earlier in the eastern sags than in the western sags. Anomalously accelerated tectonic subsidence occurred at 17.5-16.4 Ma during the post-tiffing stage, with average subsidence rates as high as 301.9 m/Myr. This distin- guishes the Pearl River Mouth Basin from classical Atlantic passive continental marginal basins, which demonstrate exponentially decaying post-rift tectonic subsidence.

The South China Sea began to outspread in the Oligocene. A great quantity of terraneous detritus was deposited in the northern continental shelf of the sea, mostly in Pearl River Mouth Basin, which constituted the main paleo-Pearl River Delta. The delta developed for a long geological time and formed a superimposed area. Almost all the oil and gas fields of detrital rock reservoir distribute in this delta. Thirty-three oil sandstone core samples in the zhujiang Formation, lower Miocene （23-16 Ma）, were collected from nine wells. The illite samples with detrital K feldspar （Kfs） separated from these sandstone cores in four sub-structural belts were analysed by the high-precision 40Ar/39Ar laser stepwise heating technique. All 33 illite 40Ar/39Ar data consistently yielded gradually rising age spectra at the low-temperature steps until reaching age plateaus at mid-high temperature steps. The youngest ages corresponding to the beginning steps were interpreted as the hydrocarbon accumulation ages and the plateau ages in mid-high temperature steps as the contributions of the detrital feldspar representing the ages of the granitic parent rocks in the provenances. The ages of the detrital feldspar from the zhujiang Formation in the four sub-structural belts were different：（1） the late Cretaceous ages in the Lufeng 13 fault structural belt; （2） the late Cretaceous and early Cretaceous-Jurassic ages in the Huizhou 21 buried hill-fault belt; （3） the Jurassic and Triassic ages in the Xijiang 24 buried hill-fault belt; and （4） the early Cretaceous - late Jurassic ages in the Panyu 4 oil area. These detrital feldspar 4~Ar/39Ar ages become younger and younger from west to east, corresponding to the age distribution of the granites in the adjacent Guangdong Province, Southern China.

The low-temperature and low-pressure artificial hydropyrolysis experiment proves that at the immature-low mature thermal evolution stage of source rock, the condensation reaction and the thermal degradation reaction occur continuously and simultaneously in both soluble organic matter and insoluble organic matter. This process was called 'antipole evolution',

Noble and active gases are released from geological samples during gas extraction for noble gas isotope analyses. The active gases should be removed before inletting to mass spectrometers for the analyses. The normal noble gas preparation systems can clean up most geological samples. However, authigenic minerals from sedimentary rocks in oil/gas fields contain organic matter, which cannot be cleaned up by the normal preparation systems and thus influence the noble gas analyses. We introduce a novel gas purification system （PRC patent No. ZL201320117751.2）, which includes several reversible purification pumps with different absorbing and degassing temperatures. It can well clean up water steam, carbon dioxide and organic gas- es. Mica minerals are often used for 40Ar/39Ar dating. A muscovite sample （2082MS） which could not be cleaned up by the normal preparation system with two SAES NP10 getters, becomes the test sample for a comparative experiment in this study. The experiment is assigned into 4 sections with the organic gas removal system （OGRS）＂Closed/Opened＂ in turn. When the OGRS is closed only with two NP10 getters for purification, the 40At intensities increase in curves with inlet time because of impurities, the 40Ar/39Ar dating results yield age errors about ＋2%-±1% （20-）. When the OGRS is opened for purification, in contrast, the 40Ar intensities decrease linearly with inlet time. This indicates that the gases have been cleaned up effectively, and the 40Ar/39Ar results yield ages with errors in ±0.4%. The OGRS is very helpful to obtain high-quality analysis data.

PY30-1构造是珠江口盆地番禺低隆起一个发育底辟体的重要含油气构造,为揭示其油气成藏规律,在确定该构造存在热流体活动的基础上,研究其油气来源和超压演化,并进一步分析油气成藏过程。镜质体反射率（Ro）、蒙脱石—伊利石矿物不正常转换和流体包裹体均一温度均指示PY30-1构造存在热流体活动,热流体活动的同时伴随烃类的运移。油源分析结果表明PY30-1构造中的油气主要来自白云凹陷恩平组煤系烃源岩,文昌组泥岩为次要烃源岩。地层压力演化史模拟结果表明：由于受珠琼运动二幕、南海运动和东沙运动的影响,白云凹陷存在3期压力释放过程,分别是在距今37~40 Ma、31~33 Ma和0~16 Ma,最后一期压力释放与油气充注期具有很好的一致性。研究认为PY30-1构造中的油气是东沙运动引起白云凹陷压力释放,使得烃类从烃源岩中排出沿底辟构造中的断裂垂向运移的结果。

位于南海北缘的珠江口盆地深水区作为我国海洋油气勘探的重点区域,具有良好的油气勘探前景。本文利用钻井地热测量数据分析了珠江口盆地深水区现今地温场及岩石圈热结构特征,通过古温标反演和拉张盆地模型正演相结合的方法定量揭示了白云凹陷新生代以来的热史,总结了不同地热地质条件对油气生成的影响。研究结果表明:珠江口盆地大地热流分布特征具有北低南高的特点,同时具有“热幔冷壳”的特征。珠江口盆地深水区始新世以来经历了两期拉张过程,第一期(47.8~33.9 Ma)拉张自始新世发生,拉张强度较大,凹陷中心基底热流快速上升至~82 mW/m^2;第二期(23~13.8 Ma)拉张发生于中新世,此次拉张在白云凹陷南部更强烈,白云凹陷主体在13.8 Ma达到最高古基底热流,此后进入热沉降阶段,基底热流值一直缓慢下降。磷灰石裂变径迹、磷灰石(U-Th)/He及锆石(U-Th)/He联合反演给出了最高古地温在13.8 Ma附近达到,后期温度基本稳定。

珠江口盆地发现的油气资源主要集中在拗陷期沉积的中新统-渐新统,在断陷期沉积的始新统中找到的油气仅占已发现油气资源的8%,而在中生代古潜山领域尚未获得商业性油气发现。富烃洼陷是否有大量的油气仍保存在中-深层的断陷层系内,古近系和中生代古潜山(“双古”)地层油气运-汇通道是否有效发育,成藏动力的强弱,以及圈闭和储-盖组合是否发育等是古近系和中生代古潜山领域勘探面临的主要问题。基于“源-汇-聚”评价思想,通过对珠江口盆地惠州26洼的源(烃源岩类型与质量、热成熟演化史与生排烃史、油气资源类型与规模)、汇(运-汇单元、运-汇方向、输导通道、汇聚强度)、聚(二级构造带与圈闭、储-盖组合、充注强度、保存条件)等静态和动态成藏要素相结合进行深入研究,揭示了惠州26洼古近系和中生代古潜山领域的源-汇-聚特征,提出了“油型烃源岩晚期加快熟化、先油后气、断-压双控、源-储对接强势供烃、立体运聚”动态成藏模式,推动了惠州26-6构造古近系和中生代古潜山新领域勘探获得重大突破。
