综合录井数据处理方法

Processing method for mud logging data

录井对应深度采集的数据一般只有步长为整米的对应数据,不利于薄互层及裂缝性油气层的解释评价,对应迟到时间的数据受钻井停、开泵的影响,造成数据不连续且失真。针对存在的这些问题,开展了综合录井剖面井深处理方法研究,阐述了利用程序实现数据处理与转换的条件及实现过程,建立了气测数据的管路延时回归处理方法、录井数据的时间-深度转换处理方法。应用经处理或转换后的数据进行油气层的识别,适应了解释评价向精细且定量化发展的需要。

Dealing with the data corresponding to mud logging depth,the data with common step width are obtained generally corresponding to a meter,which is no benefit to the interpretation and evaluation of thin inter-beds and fractured oil and gas zones.And the data corresponding to the lag time are discontinuous and false under the influence of drilling pump stopping and starting.In view of the above conditions,the method study on processing the depth profile of the comprehensive mud logging was carried out.The author states the condition and process of realizing data processing and transferring by using programs,sets up the regression processing method of pipeline time-delay for gas logging data and the processing method of time-depth transmission for mud logging data.Applying data which is processed and transferred to carry out oil and gas distinguishing can meet the needs of the development of interpretation and evaluation to fine and quantification.
