【摘要】：随着水平井技术在油气勘探开发领域的广泛应用,水平井测井解释逐渐成为测井解释工作的重要研究内容之一。本文以新疆风城油田齐古组稠油油藏水平井为研究对象,在常规直井测井解释方法基础上,应用三维有限元数值模拟的方法对研究区水平井进行曲线校正。在综合利用岩心资料、测井资料以及地质资料的基础上,本文首先对研究区齐古组进行储层特征和"四性关系"研究,详细分析储层岩性、物性、电性、含油性特征及其相互间的关系。其次,基于三维有限元分析法,模拟不同测井环境,对水平井双侧向电阻率测井进行环境影响因素分析,得出水平井双侧向主要影响因素是层厚和围岩,再根据研究区地层环境,分水平井井轴位置居中、不居中两种情况进行数值模拟,得到适合研究区水平井双侧向测井的校正图版和公式,利用校正公式对水平井进行校正处理。紧接着,在岩心归位后,建立了符合研究区储层的测井解释参数模型,包括泥质含量计算模型、孔隙度模型、渗透率模型、饱和度模型。最后,在实际应用过程中,选取水平井邻近直井的相同目的层段取芯参数,与校正、解释后的水平井进行对比,检验校正效果,发现校正后的水平井测井解释结果更加符合储层参数特征。本文通过以上研究,得出了一套符合研究区水平井的处理、解释方法,为油田后期水平井测井解释工作提供了参考。
[Abstract]:With the wide application of horizontal well technology in the field of oil and gas exploration and development. Horizontal well logging interpretation has gradually become one of the important contents of logging interpretation. This paper takes the horizontal well of Qigu formation heavy oil reservoir in Fengcheng Oilfield Xinjiang as the research object and based on the conventional straight well logging interpretation method. The 3-D finite element numerical simulation method is used to calibrate the horizontal wells in the study area. Based on the comprehensive use of core data, logging data and geological data. In this paper, the reservoir characteristics and "four properties" of Qigu formation in the study area are studied firstly, and the lithology, physical properties, electrical properties, oil content and their relationships are analyzed in detail. Secondly, based on three-dimensional finite element analysis. Simulation of different logging environment, horizontal well dual lateral resistivity logging environmental impact factors analysis, the horizontal well dual lateral main factors are formation thickness and surrounding rock, and then according to the formation environment in the study area. The horizontal well axis is in the center, but not in the middle, and the correction chart and formula suitable for the horizontal well dual lateral logging in the study area are obtained. The correction formula is used to correct the horizontal well. Then, the correction of the horizontal well is carried out. After the core is located, the logging interpretation parameter model is established, including the mud content calculation model, porosity model, permeability model, saturation model. Finally, in the practical application process. The coring parameters of the same target interval in the horizontal well adjacent to the vertical well are selected and compared with the corrected and interpreted horizontal wells to verify the correction effect. It is found that the corrected logging interpretation results are more in line with the reservoir parameters. Through the above research, a set of processing and interpretation methods for horizontal wells in accordance with the study area are obtained. It provides a reference for the logging interpretation of horizontal wells in the late stage of oil field.
