中国陆相致密油储层具有岩性复杂、孔隙结构复杂、非均质性强等特点,常规测井难以准确评价岩性、物性、电性、含油性、烃源岩特性、脆性和水平地应力各向异性,本文综合应用“无源三组合”测井(岩性扫描测井、致密储层核磁共振测井和介电扫描测井)、声波扫描测井、微电阻率成像测井等测井新技术,结合传统“三组合”测井技术,总结出了陆相致密油测井评价思路,目的是解决烃源岩品质、储层品质和工程品质“三类品质”评价问题。运用该思路,对松辽盆地北部Q地区高台子油层测井新技术资料相对齐全的J2井和Q1井,进行精细测井评价,同时,结合常规测井资料,建立了相应的“七性”评价模型,并将模型用于研究工区内20口老井资料的解释,取得了良好效果。最终,在测井精细评价基础上初步建立储层分类标准,形成了一套陆相致密油评价体系。相比常规测井,测井新技术将以其独特优势支持我国陆相致密油勘探开发的深入进行。
The terrestrial oil-tight reservoirs in China are characterized by complex lithology, complex pore structure and strong heterogeneity. Conventional logging is difficult to accurately evaluate lithology, physical property, electrical property, oiliness, source rock characteristics, brittleness and level Stress anisotropy, this paper integrated application of “passive three combination” logging (lithology scanning logging, tight reservoir NMR logging and dielectric scanning logging), acoustic scanning logging, micro-resistivity imaging measurement Wells and other logging new technologies, combined with the traditional “three combinations ” logging technology, summed up the continental tight oil logging evaluation ideas, the purpose is to solve the source rock quality, reservoir quality and engineering quality “three types of quality ”Evaluation problem. Using this train of thought, fine logging evaluation is carried out on Well J2 and Well Q1 which have relatively new logging data of Gaotaizi well logging in the Q area of northern Songliao Basin. At the same time, with the combination of conventional well logging data, a corresponding “ ”Evaluation model, and the model is used to study the data interpretation of 20 old wells in the work area, and achieved good results. Finally, the reservoir classification standard was initially established on the basis of well logging evaluation, and a set of evaluation system of continental tight oil was formed. Compared with conventional logging, new logging technology will support the in-depth exploration and development of continental tight oil with its unique advantages.
