【摘要】：世界能源消费量的不断激增与日益突出的供需矛盾明显,上世纪九十年代后,人们逐渐重视起非常规天然资源,很多国家重要的议事中都提到了非常规油气资源的勘探开发,21世纪重要补充能源中,非常规油气资源被列入其中。美国是最早开发页岩气的国家,目前在美国已经取得成功,从世界范围上来说,我国是页岩气资源量最丰富的国家,但是因为我国页岩气藏的勘探开发起步较晚,许多页岩气勘探和开采关键技术还不成熟。在非常规能源中页岩气的潜力巨大,很多国家相关机构和石油公司开始越来越重视页岩气。然而,目前对某地区页岩气地质储量的计算和页岩储层的评价仍然是需要解决的问题。页岩气的储集层孔隙结构对页岩气的储集能力有影响,同时页岩气储层孔隙结构对页岩气井的产量和最终采收率也有影响。经大量的研究发现,有大半的页岩气存储在孔隙中,岩石孔隙是页岩气主要赋存的空间。对页岩气储层的评价就是对页岩气的孔隙结构研究,页岩孔隙结构研究对页岩气勘探开发具有重要的指导性意义。论文将通过页岩气储层孔隙结构分析,利用页岩气测井评价方法,以评价储层、计算页岩地质储量作为主要研究内容,最终达到对页岩气的合理分布预测目的。本论文对页岩有效储层识别和某区青一段泥页岩有利区地质资源量的计算进行了具体应用。并且利用了页岩气资源量计算里最普遍、最准确的体积法计算。最终结果表明,获得页岩有效储层可以应用测井定量评价法。同时,可以通过页岩气有利区各参数优选,并结合页岩气资源体积法基本原理,确定相关参数,最终计算得到该地区青一段泥页岩页岩气的含气量。
[Abstract]:The increasing increase in world energy consumption and the increasingly prominent contradiction between supply and demand are obvious. Since the 1990s, people have gradually attached importance to unconventional natural resources. The exploration and development of unconventional oil and gas resources have been mentioned in the important deliberations of many countries. Among the important supplementary energy sources in the 21st century, unconventional oil and gas resources have been included in the list. The United States was the first country to develop shale gas, and has now achieved success in the United States. China is the country with the most abundant shale gas resources in the world, but the exploration and development of shale gas reservoirs in China started relatively late. Many key technologies for shale gas exploration and exploitation are not yet mature. The potential of shale gas in unconventional energy sources is so great that many national institutions and oil companies are beginning to pay more and more attention to shale gas. However, At present, the calculation of shale gas geological reserves and the evaluation of shale reservoirs are still problems to be solved. The pore structure of shale gas reservoir has an effect on the reservoir capacity of shale gas. At the same time, the pore structure of shale gas reservoir also has influence on the production and final recovery of shale gas wells. After a lot of research, it is found that most of the shale gas is stored in the pores. Rock pore is the main space of shale gas. The evaluation of shale gas reservoir is to study the pore structure of shale gas. The study of shale pore structure has important guiding significance for shale gas exploration and development. This paper will analyze the pore structure of shale gas reservoir and use shale gas logging evaluation method to evaluate the reservoir. The calculation of shale geological reserves as the main research content, Finally, the reasonable distribution of shale gas is predicted. In this paper, the effective reservoir identification of shale and the calculation of geological resources in the favorable area of the first member of shale in a certain area have been applied concretely, and the calculation of shale gas resources is the most common in the calculation. The most accurate volume method is calculated. The final result shows that the logging quantitative evaluation method can be used to obtain the effective shale reservoir. At the same time, the parameters of shale gas favorable zone can be optimized, and the basic principle of shale gas volume method can be combined with the basic principle of shale gas resource volume method. The relevant parameters are determined and the gas content of shale gas in the first member of Qinghai is calculated.
