摘　　要：针对复杂断块老油田地层对比方面所存在的一系列难题,在广泛消化前人研究成果的基础上,提出了一套强调综合分析和运用地面露头、地震资料、测井资料、测试资料等所能提供的一切有用信息,并使之相互配合、相互验证,进而达到精确地层对比的综合方法——"地震测井结合、分块分级对比"的小层对比方法。该方法综合利用测井资料纵向上的高分辨率优势和地震资料横向上的优势对砂层组进行识别及划分对比,此外,还应用油田开发过程中丰富的生产动态资料进行方案的验证和必要的调整,从而达到动态资料与井震资料的统一。该方法在现已处于开发中后期的缅甸PYAY油田的应用中取得了很好的效果,对断层展布特征和油水系统均取得了新的认识,并克服了原方案划分方法较笼统、精度不足等缺点。因此,在方法研究和实际应用中都取得了新进展,建立了一套专门针对类似的复杂断块老油田开展精细地层对比研究的工作模式和技术方法模式。Aimed at a series of difficulties about stratigraphic correlation in complicated fault-block field, a method of stratigraphic classification and correlation is proposed, which puts the stresses on the using of the data from outcrop, seismic horizon, logging and dynamic performance. This method utilizes the advantages from logging data in the vertical direction and seismic data in the horizontal direction to carry out the recognition and correlation of sand. Good effects have been achieved in the application of this method for the fine stratigraphic classification and correlation in PYAY Field in Burma and new cognitions about fault distribution are obtained. A technical model of fine stratigraphic correlation for the similar complicated fault-block oilfield is established.
