【摘要】：本论文根据实际科研项目需求,主要开展了优质油气储层--甜点的地震预测方法研究及应用。基于新疆准噶尔盆地玛东YB井区的实际资料,对研究区百口泉组油气储层甜点的主控因素进行了研究,总结出该区油气储层甜点主控因素主要有:有利沉积相带;裂缝发育程度;岩性和物性有利区等。针对甜点主控因素,选取合适的地震预测方法,结合地质、钻测井等资料开展了针对这些主控因素的地震识别和预测,形成了研究区储层甜点的地震预测的方法系列及工作流程。将这些方法和流程应用到研究区实际的优质储层预测中,取得较好效果,为研究区的勘探部署提供了科学依据。本次论文还重点进行了油气储层甜点的地震响应特征的分析研究,主要利用正演模拟的手段,对不同沉积相带及砂体叠置等情况下,地震响应特征的变化规律进行了研究。总结出了一些利用地震属性分析沉积相带的理论依据以及识别砂体叠置的辨别方法等,为该地区甜点储层的精确识别奠定了基础。本次研究解释了YB井区的断裂系统,落实了YB2、YB1块断块圈闭。研究认为研究区裂缝系统主要为断层伴生裂缝为主,裂缝发育带主要处于大断裂带附近。综合优质储层各个主控因素的预测,认为研究区目的层总共有2块储层甜点发育带,分别为YB2井甜点区和YB1井甜点区。以上研究成果为研究区的勘探部署提供了有利的支撑。本次研究所建立的油气储层甜点地震预测方法技术及工作流程对于研究区及类似地区今后的油气储层甜点预测工作具有重要的参考价值,并可以在相似地区应用。
[Abstract]:According to the demand of actual scientific research project, this paper mainly develops the research and application of seismic prediction method of high quality oil and gas reservoir-desserts. Based on the actual data of Madong YB well area in Junggar Basin, the main controlling factors of oil and gas reservoir desserts of Baikouquan formation in the study area are studied. The main controlling factors of oil and gas reservoir desserts in this area are summarized as follows: favorable sedimentary facies belt; Fracture development degree; lithology and physical property favorable areas, etc. According to the main control factors of dessert, the suitable earthquake prediction method is selected, and the seismic identification and prediction for these main control factors are carried out in combination with geological, logging and other data. The method series and work flow of seismic prediction of reservoir desserts in the study area were formed. These methods and processes are applied to the actual high quality reservoir prediction in the study area, and good results are obtained, which provides a scientific basis for the exploration and deployment of the study area. This paper also focuses on the analysis and study of seismic response characteristics of oil and gas reservoirs. By means of forward modeling, the variation of seismic response characteristics in different sedimentary facies zones and sand bodies is studied. The theoretical basis for analyzing sedimentary facies zones by seismic attributes and the discrimination methods for identifying sand bodies are summarized, which lays a foundation for the accurate identification of dessert reservoirs in this area. This study explains the fault system in YB well area and implements the fault block trap of YB _ 2 and YB _ 1 block. It is considered that the fracture system in the study area is mainly fault-associated fractures, and the fracture development zone is mainly located near the great fault zone. Based on the prediction of the main controlling factors of the high quality reservoir, it is considered that there are two zones of dessert development in the target layer of the study area, namely, the dessert zone of YB2 well and the dessert zone of YB1 well. The above research results provide favorable support for the exploration and deployment of the study area. The seismic prediction method and workflow of oil and gas reservoir established in this paper have important reference value for the future prediction of oil and gas reservoirs in the study area and similar areas, and can be applied in similar areas.
