利用测井曲线进行地层精细划分与对比

摘要

Formation division and correlations of strata is of great importance for the lithologic reservoir exploration because it will directly affect the accuracy of the cognition of individual sand body and lithologic reservoir forecast and oil-gas distribution. Duo to the limitation of limited the coring well and data, when the oil field development comes to its Medium-late Stage, it will take advantage to use well logging data to divide and compare the formation. Only when we divide the formation according to geology regularity and build the correct isochronous correlation, find the reasonable first well and the right comparison way can we build the reasonable geology frame to guide the proper development of oil-gas reservoir.%地层划分与对比直接影响单砂体识别的准确性和预测油藏及油气的分布规律，所以地层划分与对比对勘探开发及岩性油藏探区具有重要的意义。随着油田开发进入到了中后期，开发节点的增加受到取芯井及其他井资料的限制，利用测井曲线进行地层的划分与对比占有绝对的优势。根据地质规律划分地层并建立正确的等时对比，确定合理起始井以及正确的对比路线，建立合理的地质框架对油气田的合理开发有重要指导作用。
