吉林腰英台油田油水分布特征及成因探讨     

殷红 《江苏地质》2005,29(1):28-31

腰英台油田是东北地区新发现的油田，目前刚开始勘探开发，在勘探开发初期遇到不少问题。其中之一是开采时高含水：就油田的实际油水分布特征进行了分析，分析油水同出的可能原因，认为这是受油藏储层物性及构造幅度和实际油柱高度的影响，由于储层低孔、特低渗。实际构造幅度低，实际油柱高度大多低于油藏产纯油所需的油柱高度，致使油藏大都处于油水过渡带。故开采时多含水，油水同出。根据这一分析，认为进一步的油气勘探重点考虑西部水下冲积扇的有利部位。此处储层物性好，有利于接受更多油源。  相似文献

塔里木盆地碳酸盐岩主要分布于台盆区寒武系—奥陶系,它既可以作为油气的储层和源岩,也可以作为油气的盖层或遮挡体。碳酸盐岩主要发育于碳酸盐岩台地相和斜坡相之中,其中开阔台地及台地边缘坡折带的生物碎屑滩和砂屑滩、局限台地的白云岩坪是主要的储集相带。潜山溶孔溶洞型白云岩、石灰岩及礁滩复合体中的生物碎屑灰岩、砂屑灰岩、鲕粒灰岩、礁灰岩以及潮坪白云岩是主要的储集岩。寒武系—下奥陶统、中—上奥陶统都发育有较好的碳酸盐岩烃源岩。根据油气的分布与聚集特点,对碳酸盐岩油气藏作了分类。论述了塔里木盆地碳酸盐岩油气勘探的前景和重要目标。  相似文献   

Utility Efficient Frontier: An Application in the Oil and Gas Industry   总被引：1，自引：0，他引：1  

Mansoor Hamood Al-Harthy 《Natural Resources Research》2007,16(4):305-312

Current practice shows that the use of portfolio and utility theory is very low among petroleum companies. This article advocates the use of both portfolio theory and utility theory as decision-making tools to improve performance of oil and gas companies. We introduce a model that can be practically used and applied in the oil and gas industry. This model generates an optimized, efficient portfolio and, at the same time, enables the decision maker to incorporate his risk attitude and policy. This can only be done by combining both the portfolio theory and utility theory through an approach called the utility mean-variance model. A typical oil portfolio optimization problem is investigated by applying both portfolio and utility theories. Through the utility mean-variance model, an efficient frontier that captures decision maker risk attitude is achieved.  相似文献   

从已发现的油气田看中国海相油气勘探   总被引：5，自引：1，他引：5  

张抗 《海相油气地质》2002,7(2):1-14

中国海相油气勘探的主要目标是古生界碳酸盐岩,在漫长的演化历程中它的主要成藏类型是准原生型。对形成保存至今的工业油气藏来说,碳酸盐岩中有效烃源岩的总有机碳含量下限应≥0.5%,滨海相或海陆交互相煤系可对生烃作出重大贡献。碳酸盐岩中的储集体受裂缝—岩溶发育程度的控制而分为三种基本类型:(1)以孤立的缝洞储集体为主者称纳溪型,各储集体内的流体性质、压力均可有不同;(2)各储集体间相互连通从而有统一的压力和气、油、水界面,若其似块状者称任丘型,若其似层状者则称威远型;(3)居于这两个端元间的过渡类型为塔河型,其各部分之间的流体性质和压力可有一定差别,无统一油水界面。应注意对似层状储集体的勘探研究,保存条件的好坏对海相油气田有决定性的意义。在分析复杂的多期成藏史中,要注意古隆起和晚期成藏的辩证关系。我国的海相油气勘探有难度,要重新评价有效和高效烃源岩,从较浅部和次生油气蒇入手逼近油气源,寻找主力油气藏,要重视岩性圈闭和各构造(形变)层间的不吻合性。中国的海相油气勘探方向可分为优先勘探、立争突破、劣中选优三个层次。  相似文献

Palynostratigraphy and palynofacies indications of depositional environments and source potential for hydrocarbons: the mid Cretaceous Nahr Umr and lower Mauddud formations, Iraq   总被引：1，自引：0，他引：1  

T. K. Al-Ameri  T. K. Al-Najar  D. J. Batten 《Cretaceous Research》2001,22(6):735

Palynomorphs recovered from core and cuttings samples from five boreholes in the East Baghdad Oilfield indicate a mid Albian–early Cenomanian age-range for the Nahr Umr Formation and the lower part of the overlying Mauddud Formation. Two palynomorph zones and four types of palynofacies have been identified. The latter are interpreted to indicate delta-top swamp and marsh, silty–muddy deltaic, inner silty and carbonate-rich platform, and limestone-platform environments. The palynofacies of the two types of platform accumulations suggest that these are potential sources of biogenic methane and condensates, and may yield more liquid hydrocarbons in areas where the formations are at greater depths than within the region studied.  相似文献

Meso-scale testing and development of test procedures to maintain mass balance     

Bonner J  Page C  Fuller C 《Marine pollution bulletin》2003,47(9-12):406-414

The Conrad Blucher Institute for Surveying and Science (Texas A&M University––Corpus Christi) has conducted numerous petroleum experiments at the Shoreline Environmental Research Facility (Corpus Christi, Texas, USA). The meso-scale facility has multiple wave tanks, permitting some control in experimental design of the investigations, but allowing for real-world conditions. This paper outlines the evolution of a materials balance approach in conducting petroleum experiments at the facility. The first attempt at a materials balance was during a 1998 study on the fate/effects of dispersant use on crude oil. Both water column and beach sediment samples were collected. For the materials balance, the defined environmental compartments for oil accumulation were sediments, water column, and the water surface, while the discharge from the tanks was presumed to be the primary sink. The “lessons learned” included a need to quantify oil adhesion to the tank surfaces. This was resolved by adhering strips of the polymer tank lining to the tank sides that could be later removed and extracted for oil. Also, a protocol was needed to quantify any floating oil on the water surface. A water surface (oil slick) quantification protocol was developed, involving the use of solid-phase extraction disks. This protocol was first tested during a shoreline cleaner experiment, and later refined in subsequent dispersant effectiveness studies. The effectiveness tests were designed to simulate shallow embayments which created the need for additional adjustments in the tanks. Since dispersant efficacy is largely affected by hydrodynamics, it was necessary to scale the hydrodynamic conditions of the tanks to those expected in our prototype system (Corpus Christi Bay, Texas). The use of a scaled model permits the experiment to be reproduced and/or evaluated under different conditions. To minimize wave reflection in the tank, a parabolic wave dissipater was built. In terms of materials balance, this design reduced available surface area as a sink for oil adsorption.  相似文献
