摘要
莺琼盆地已进入以大型重力流岩性圈闭为主的勘探阶段,该类储集体纵向期次多,横向相变快,微相丰富,而海上钻井少,取心成本高,高分辨率电成像测井资料在解决微相及优质储层识别与预测等方面有较好的应用。采用从已知到未知的基本原理,利用岩心或井壁取心资料刻度成像图像,再用刻度后的成像图像识别和建立精度更高的岩性剖面;通过岩性精细解释和典型沉积构造识别,指出不同沉积微相的判别特征,以及有利储集微相的特征;通过交错层理的识别,寻找受底流改造过的优质甜点储层分布。应用实践表明,在大型重力流储集体的勘探过程中,应用成像测井技术可以达到提高沉积学研究精度和降本增效的作用。
The exploration of the Yingqiong basin has turned into the main exploration stage of large gravity flow lithologic traps. But this reservoir is often multi-stages and abruptly changes in facies in lateral, sedimentary microfacies are rich; the number of offshore drilling is small, but the cost is high. High resolution electric imaging logging data are better used in solving difficult problems such as sedimentary microfacies and prediction of high quality reservoir. Its application is. Using the basic method from known to the unknown, identify lithology with the core calibration FMI image, build more accurate lithologic sections; By fine interpretation of lithology and identification of micro sedimentary structures, the features of different sedimentary microfacies and the characteristics of high quality reservoir are pointed out; Through identification of cross bedding, looking for dessert reservoir which is reworked by bottom current. Applications of this technology in Yingqiong basin prove that application of imaging well logging technology can improve the research definition of sedimentology facies, and reduce cost and improve efficiency in the process of large scale gravity flow reservoir exploration.
