列的焦油在许多中东地区碳酸盐岩储层存在。沥青垫的存在已经成为最严重的问题之一,在石油行业,还有额外的影响(IOR)采油技术。本身。沥青垫,大多是半固态暗棕色到黑色,可以从一个油藏隔离含水层。了解沥青垫,能够描述和识别它们是至关重要的减少生产成本和战略原油生产。这里介绍研究的目的是描述高粘性沥青油的理化性质。五焦油核心来自科威特的碳酸盐岩储层和13个样本准备从每个焦油胡萝卜。从每个样本用于评估一个核心在提取之前,而另12被用于评估与甲苯萃取后,C, 135°C, 225°C,和315°C)。热的沥青油样品进行了分析使用新技术如macro-primary分析不同的106年,热解Rock-Eval 6,索氏仪器和薄层色谱法。Rock-Eval 6热解的结果表明,科威特的碳酸盐岩储层是石油/天然气的主题(干酪根类型会和ll-lll)。大多数的样本热成熟和良好的生烃。 However, These samples were produced from oil. In addition, the H / C ratio increased as the API decreased. In addition, the results showed that most of the parameter values, while hot water and surfactant, were only slightly affected. hydrocarbons. However, the oil could not have been produced from these samples. In addition, the H / C ratio increased as the API decreased. In addition, the results showed that most of the parameter values, while hot water and surfactant, were only slightly affected. hydrocarbons. However, the oil could not have been produced from these samples. In addition, the H / C ratio increased as the API decreased. In addition, the results showed that the toluene had the most impact on the parameter values. Tar mats are very common in Kuwait and are usually located at the bottom of the oil column. In petroleum tanks, the thickness of the column of tar mats can vary even in the same tank and can reach a few hundred feet of tar mats with petroleum or extra heavy bitumen and have API ° and / or viscosity in situ above 10,000 cp. Due to their high content of asphaltenes, the order of 20 to 60% of their weight, the tar mats have a low gravity and a high viscosity according to Wilhelms and Larter. Asphaltenes are the highest molecular weight hydrocarbon components of petroleum. The tar mats are located near the base of the oil buildup or near the surface when the oil infiltrates. Geochemical studies have shown that the thermal formation of a number of causes is related to Moore and Hirschberg. Most researchers believe that tar mats are formed by the combination of asphaltenes or variations in the oil column, which causes differences in oil viscosity. Five tar cores were selected from a carbonate tank in Kuwait at depths of 2,674 ft, 2,703 ft, 2,723 ft, 2,755 ft and 2,782 ft. Then, 13 samples were taken from each core; One sample from each carrot was used for evaluation before extraction, and the other for 12 The properties of tar mats can vary depending on the depth and area of the same field. Analysis of physical properties / water. Elemental analysis of the tar carpet samples showed that the H / C ratio increased as the API gravity decreased. Rock-eval 6 and TOC analyzes have shown that most tarp carpet samples have excellent generation potential. These samples had high TOC values (> 4% by weight) and S2 pyrolysis values between 38.88 and 73.54 mg HC / g rock. The HI versus Tmax and OI diagrams showed that this formulation was composed of types II and II / III kerogens of terrestrial or marine origin capable of emitting oil and gas. In addition, the values of Tmax, transformation ratio (PI) and reflectance of vitrinite (% Ro) suggest that this formation went from immature to maturity. Based on the assessment of organic matter, the five tar cores taken from the samples The SARA analysis of the results showed that the tar carpet samples contained less resins and asphaltenes than saturated and aromatics. In addition, the Colloid Instability Index (CII) values were calculated using the SARA method of predicting the stability of crude oil. Samples AB3, AB4 and AB5 had lower CII values, 9 0.9, indicating that their deposition of asphaltenes tended to be aromatic and resinous. On the other hand, the CII value was greater than 0.9 for the samples AB1 and AB2, which are two of these samples,
