摘要

摘要: 由于致密油藏勘探开发成本高，如何实现致密油效益开发是当前亟需解决的问题。针对鄂尔多斯盆地红河油田长8致密油藏特点，突出单井信息，从影响致密油藏经济性的关键参数——单井经济可采储量入手，建立了一套基于单井经济可采储量的致密油藏效益开发地质评价参数确定方法和流程。针对红河油田长8致密油藏单井可采储量受裂缝控制的特殊性，油藏地质评价参数的确定增加了裂缝发育程度，选取单井技术可采储量、有效厚度、有效孔隙度、含油饱和度和裂缝发育程度5个参数进行分类，细分为6种类型。通过单井技术可采储量与有效厚度交会图，对照2种情景下的经济下限和油藏地质参数分类, 综合确定油藏地质参数下限。该方法在红河油田长8油藏取得了良好的实用效果，可为国内致密油藏“甜点区”的筛选和开发部署优化提供技术支撑。

Abstract: Due to the high cost for exploration and development of tight oil reservoirs, it is an urgent problem to achieve profitable development of tight oil. According to the characteristics of tight oil reservoir in the eighth member of Triassic Yanchang Formation (Chang 8) in Honghe oil field, Ordos Basin, this paper highlighted single well information, started with the key parameters affecting the economic benefit of tight reservoir-single well economically recoverable reserves, and established a series of determination methods and process of geological evaluation parameters for profitable development of tight oil reservoirs based on single well economically recoverable reserves. Considering the particularity that the single well recoverable reserves of Chang 8 tight oil reservoir in Honghe oil field was controlled by fractures, the fracture development degree was added in the study of determination of the geological evaluation parameters. Five parameters, including single well technically recoverable reserves, net pay thickness, effective porosity, oil saturation and fracture development degree, were selected for classification and subdivided into six types. By compiling the intersection diagram of single well technically recoverable reserves and net pay thickness, the cutoffs of geological parameters were determined comprehensively by comparing the economic cutoffs and the classification of reservoir geological parameters under two scenarios. The method was applied to Chang 8 reservoir in Honghe oil field, and its feasibility was verified. The practical application shows that this method can provide effective technical support for sweet spot screening and development and deployment optimization in tight reservoirs.
