Sub-sag A3 and A4 are potential hydrocarbon kitchens. The crude oil belongs to typical continental oil and main originates from the Wenchang Formation source rock, however, Enping Formation has the li-mited contributions. The study area has two petroleum systems, which are the north and south of Lu-feng sag petroleum systems. Crude oil of the south of Lufeng sag petroleum system originates from Wenchang Formation in A3 subsag, secondly, from A4 subsag. Crude oil of north of Lufeng sag petro-leum system main originates from A3 subsag Wenchang Formation, and at the same time, a spot of oil originates from A2 subsag Wenchang Formation and Enping Formation. Lufeng sag has two stages of hydrocarbon charge. The earlier first stage started before in Middle Miocene (12.89~10.05 Ma), with mainly low liquid hydrocarbon. The second stage sated before in Late Pliocene (2.52 Ma), with mainly mature hydrocarbon. In a word, the oil-gas exploration direction should be given priority to the deep region (Wenchang Formation) and the next important target is the early deep structure.KeywordsPearl River Mouth Basin, Lufeng Sag, Paleogene, Source Rock, Hydrocarbon Accumulation, Geochemistry珠江口盆地陆丰凹陷古近系烃源岩评价及油气成藏王玺凯1,2，郭建华1,2*，刘辰生1,2，于汪1,2，王张虎1,2*通讯作者。

尤其是在生烃凹陷的深凹陷区，一般烃源岩品质较好，但由于钻井很少，甚至没有，导致难以获取烃源岩样品。

为研究其储层特征及主控因素，以恩平凹陷A油田高泥质储层为例，对比其储层特征、开发特征和B油田常规海相砂岩储层的差异，研究表明：与常规海相砂岩储层相比，高泥质储层黏土矿物含量更高、孔喉更小、粒度更细、物性更差，开发过程中具有低阻产水、易出泥砂、能量不足的特点，明确了高泥质储层宏观上受控于弱水动力的沉积环境，细粒沉积物及黏土矿物的胶结作用是储层渗透率降低的主要因素，并对油田开发造成不利的影响。

The reservoir characteristics and development characteristics are quite different from that of conventional marine sandstone. In order to study its reservoir characteristics and main controlling factors, by taking the high argillaceous reservoir of A oilfield in Enping sag as an example, the differences of reservoir characteristics and development characteristics between it and the conventional marine sandstone reservoir of B oilfield are compared. The research shows that compared with conventional marine sandstone reservoir, high argillaceous reservoir has higher clay mineral content, smaller pore throat, finer particle size and worse physical properties. During the development process, it has the characteristics of low resistance, easy mud and sand production and insufficient energy. It makes clear that the high argillaceous reservoir is macroscopically controlled by the sedimentary environment of weak hydrodynamic force. The cementation of fine-grained sediments and clay minerals is the main factor for the reduction of reservoir permeability and has an adverse impact on oilfield development.Key words:Pearl River Mouth basin; Enping sag; sedimentary environment; marine sandstone; high argillaceous reservoir南海珠江口盆地经过30年的开发实践，形成了独特的海相砂岩高速高效开发对策和技术，这类储层在珠江口盆地可称为常规海相砂岩储层，具有物性好、分布稳定、展布范围广、连通性好、边底水天收稿日期：2021–03–30；修订日期：2021–05–17。

珠江口盆地惠州凹陷主力烃源岩测井预测及评价袁彩萍;徐思煌;薛罗【摘要】利用惠州凹陷文昌组与恩平组声波时差、自然伽马、电阻率、密度和中子孔隙度等测井参数对烃源岩有机碳含量（ TOC）的响应特征，建立了单井及惠州凹陷综合的五元回归定量预测模型。

应用该模型对12口钻井进行了泥质烃源岩TOC测井预测，获得了这些井文昌组、恩平组烃源岩连续的TOC曲线，并按陆相泥质烃源岩评价标准计算了好与很好、中等与差烃源岩的厚度。

结果表明，TOC 预测结果相对误差大多在20％内，且单井模型略优于综合模型。

层位上，恩平组中等烃源岩厚度比例在50％以上，其次为差烃源岩，好烃源岩厚度占比一般低于20％；文昌组好与很好烃源岩厚度比例大多高于75％，因此文昌组烃源岩整体优于恩平组。

横向上，惠西半地堑最优，惠东半地堑次之，惠南半地堑与惠北半地堑烃源岩相对不够发育。

烃源岩测井预测纵向分辨率高，但受钻井分布所限难于揭示烃源岩空间展布。

测井约束下综合地球物理烃源岩评价应具有更广阔的应用前景。

%The prediction models of 5 variate regression equation for individual well and the Huizhou Sag were built according to the response relationship of TOC to the well logging values of sonic transit time, natural gam-ma, resistivity, density and neutron porosity from the Wenchang and Enping Formations. By using these predic-tion models, the organic carbon content of mudstone source rocks of the Wenchang and Enping Formations of 12 wells was calculated, and the thickness of source rocks of different ranks, including good and very good, middle and poor, was obtained according to the evaluation criterion of mudstone source rocks in Chinese lacustrine ba-sins. Most relative errors of TOC predicted by welllogging are less than 20%, and the prediction results from in-dividual well model are better than those from collective model. In the Enping Formation, the source rocks of middle rank take higher percentage than 50% in thickness for most wells, poor source rocks take subdominant, and good and very good source rocks just take lower percentage than 20% in thickness. In the Wenchang Forma-tion, good and very good source rocks take higher percentage than 75% in thickness for most wells, and middle and poor source rocks just account for very small proportion in thickness. So, as main source beds in the Huizhou Sag, the Wenchang Formation is more favorable than the Enping Formation. Among 4 half-grabens of Paleogene developed in the Huizhou Sag, the western Huizhou half-graben is most favorable for source rock generation, the eastern Huizhou half-graben less, and the northern and southern Huizhou half-grabens poorest. Limited by well distribution, it is difficult to characterize the spatial distribution of source rocks even though the vertical resolu-tion of logging is high. The predication and evaluation of source rocks with the method of well-constrained com-prehensive geophysics should illustrate a wider prospect of application.【期刊名称】《石油实验地质》【年(卷),期】2014(000)001【总页数】7页(P110-116)【关键词】有机碳;测井响应;定量预测;烃源岩;古近系;惠州凹陷;珠江口盆地【作者】袁彩萍;徐思煌;薛罗【作者单位】中国地质大学构造与油气资源教育部重点实验室，武汉 430074;中国地质大学构造与油气资源教育部重点实验室，武汉 430074;中国石油勘探开发研究院西北分院，兰州 730020【正文语种】中文【中图分类】TE122.1+15烃源岩评价是含油气盆地油气资源评价的重要基础。

基于浅层断裂埋藏浅、活动晚、封闭性弱的特征, 提出穿断成藏模式成功地指导了隆起带勘探, 发现一批商业性油田。

对恩平凹陷南、北隆起带浅层主要油田成藏特征进行剖析, 阐述了浅层油气穿越未成岩断裂运移富集成藏模式及其成因机制。

断层岩弱成岩导致有限油柱封闭高度与油气强充注是其形成机制, 弱成岩是关键。

断裂‒输导砂体‒构造脊构成多次穿断运移的地层格架, 油气充注强度与圈闭汇聚能力的平衡控制穿断运移路径上圈闭的富集程度, 断‒储排替压差控制穿断过程中油气垂向侧向分流。

穿断运移成藏模式对浅层油气成藏具有一定借鉴意义。

老油田滚动开发的创新思路和实践作者：邓周荣来源：《科技创新导报》2015年第02期摘要：该文以南海东部陆丰油田FSOU单点系泊系统升级改造及移位项目为例，介绍了陆丰油田群为适应油田滚动开发需求，适时对油田布局进行调整。

该措施不仅解决了新油田对老油田老设施的依赖，提高了整个油田生产安全保障性，也减少油田间油液长途输送的能耗。

同时，通过对输送通道的扩容，解决了原有输送通道输送能力不足的问题，破解了依托老油田滚动开发的制约瓶颈。

油田设施包括LF13-1DPP平台，LF13-2DPP平台，LF13-2WHP平台，“南海盛开”号FSOU（Floating Storage and Offloading Unit，以下简称FSOU）以及正在建设的LF7-2平台。

LF13-2WHP和LF13-2DPP以栈桥连接，LF13-2DPP和LF13-1平台之间以一根12 km 12英寸海管连接，LF13-1平台和FSOU以一根2000 m 6寸输油软管连接。

陆丰油田群各个油田在不同时期开发，且开发的时间跨度较大。

1993年中海油和日本JHN公司合作开发LF13-1油田，由LF13-1平台和FSOU组成。

后期中海油独立开发了陆丰13-2油田，分别于2005年建成了LF13-2WH平台，2011年建成LF13-2DPP平台。

2013年中海油和美国新田公司合作开发的LF7-2油田也正在建设中。

陆丰油田群按原规划建成后，整个油田设施将呈串联布局（见图1）。

LF7-2生产的纯油（处理后达销售标准原油）通过13 km海底管道送到LF13-2 DPP平台，LF13-2 WHP和LF13-2DPP（两平台通过栈桥连接）油液一起经过LF13-2 DPP平台一级分离处理，再和LF7-2平台送来的纯油混合后通过已有的12 km海底管线（12寸）输送至LF13-1平台，经在LF13-1平台处理合格后，再通过软管输送到FSOU储存、外输。
