地化录井技术现状与展望

Geochemical logging technology status and prospects

通过对岩石热解、轻烃分析、罐顶气分析、热解气相色谱分析等地化录井技术的现状、优势和缺陷进行总结分析,认为轻烃录井不受样品的影响,对钻井工艺过程限制较少,同时抗污染能力较强,对气层、轻质油层、油层、油水同层及气水同层、水淹层有很高的分辨率和准确度,具有独特的技术优越性,是解决PDC、油基钻井液条件下油气层识别与评价的有效录井方法。岩屑类的录井方法需要优选,才能提高服务质量。

By summarizing and analyzing the technology status,advantages and defects for the rock pyrolysis,light hydrocarbon analysis,tank top gas analysis,pyrolysis gas chromatography analysis,the authors believe that the light hydrocarbon logging isn′ t impacted by the samples and has fewer restrictions on the drilling process with stronger anti-pollution ability and higher resolution and accuracy for the layers of gas,light oil,oil,oil and water,water and gas,and water flooding.The light hydrocarbon logging has a unique technical advantage,which is an effective mud logging method to solve the oil and gas identification and evaluation under the conditions of PDC and oil-based drilling fluid.In order to improve service quality,the cutting logging methods require the optimization.
