成像测井在砂砾岩体勘探中的应用

针对陡坡带砂砾岩扇体复杂油气勘探目标,建立适合的成像测井地质解释方法和模式;利用岩心资料对成像测井图象进行了标定,对成像图象的多解性进行了分析;结合常规测井和地震资料,对有利储层的成像特征和发育展布规律进行了探索研究;建立了砂砾岩体典型岩性和主要沉积构造的成像测井解释图版;纠正了前人在成像资料应用中存在的错误;根据在东营北带砂砾岩体沉积、储层研究中的具体应用,总结了一套完善的成像测井地质解释方法和技术流程.利用成像资料能够对砂砾岩体岩性、沉积构造做较为准确的判识,如何利用成像测井的纵向连续高分辨率实现对有利储层的精细判识是今后研究的重点.

The application of imaging logging in exploration of glutenite

Aiming at glutenite fan body, a complex exploration goal at steep slope zone, a suitable imaging logging interpre-tation method and mode were developed. The pictures of imaging logging were demarcated and multi-solution of pictures was analyzed by a great amount of core data. The imaging characteristics and distribution of favorable reservoir were studied com-bined with conventional logging and seismic data. The interpretation chart for imaging logging data of typical lithology and main sedimentary tectonics of glutenite was built. Some faults during application of imaging data in former work were correc-ted. A series of imaging logging interpretation methods and processes have been summarized according to practice in the study of glutenite in north part of Dongying formation. Exact determination for lithology and main sedimentary tectonics of glutenite can be realized by using of imaging logging data. Fine determination of favorable reservoir by using of vertical continuous high -resolution of imaging logging data is a key point for further research.
