中文摘要:
      我国稠油油藏蒸汽吞吐为主要开发方式,目前其多数区块已进入开发后期,亟需进行开发方式转换。火烧油层是蒸汽吞吐后的重要接替技术,但由于其技术要求高,对区块实施火烧油层的潜在适应性进行研究至关重要。由于原有的火驱筛选标准已产生滞后,且未形成系统的筛选方法,不足以适用于当前火驱油藏的筛选。因此需建立适应性更好、可靠性更强的火驱油藏筛选方法。对此,本文在大量调研的基础上总结国内外火烧油层矿场实例及其油藏参数,首先从油藏类型、开发历史对火驱候选油藏进行初步筛选,然后利用差异置信法及灰色关联法对油藏参数进行分析评价以建立油藏参数筛选标准,最后对于火驱预期效果的预测选用支持向量机方法。由此形成一套火驱油藏筛选评价方法,并将该方法应用于辽河油田多个区块以确定适宜火驱的候选区块,实现火驱油藏筛选的完善评价。
英文摘要:
      Cyclic steam stimulation (CSS) is an important development method of heavy oil reservoir in China. Most blocks have entered the later stage of CSS, so the replacement of development method is considered urgently. In-situ combustion (ISC) is an available replacement method after CSS, and to study the potential adaptability of ISC is essential due to the high technique requirement. But the existing reservoir screening guide lags behind, and systematic screening methods have not been proposed, which are not suitable for the current ISC project. Therefore, it’s necessary to establish a reservoir screening method with better adaptability and reliability for ISC. In this regard, this paper summarizes the field examples and reservoir parameters at home and abroad based on a lot of investigations. Firstly, the reservoir type and development history of candidate reservoir are preliminarily screened. Secondly, the reservoir parameters are analyzed and evaluated by differential confidence method and grey correlation method to establish the reservoir parameter screen guide. Finally, the support vector machine method is selected to predict the development efficiency of ISC. Based on the above steps, a method of reservoir screening and evaluation for ISC is formed and applied to several blocks of Liaohe Oilfield to determine the suitable candidate blocks, which fulfilled the optimized evaluation of reservoir screening for ISC.
