某水平井产量异常综合资料解释分析
|
摘要
国外某区块的第一口X水平井的产量比相邻的直井产量相比,差别不大,没能完成地质任务,本文系统分析对射孔、测井、录井、测试、地震资料综合分析和评价,认为各种施工作业正常,所取资料属实。同时资料综合研究表明本井的水平段钻遇的好储层有限,储层质量因泥质含量增加,储层质量变差;地震反演表明是因沉积相带发生变化。该井设计时没能进行地震资料反演,造成该并没能完成地质任务,事实表明勘探开发程序不能逾越。
There is a little difference between the first horizontal well and neighboring vertical well in some oversea block. The geological tasks did not accomplish in this horizontal well. The comprehensive analysis and evaluation, including perforation, well logging master data, well testing and seismic data proves the good reservoir intervals in the horizontal part are limited. The properties of reservoir become bad because of increase of shale volume. The seismic inversions indicate the sedimentary face has changed. No valid seismic inversions were done in the design phase of the horizontal well, which caused the geological destination didn't fulfilled in this well. The facts testify that the normal development and exploration procedure must be done before drilling well.
