地化录井解释评价技术研究

Interpretation and evaluation techniques for geochemical logging

地化录井参数较多,每一个参数都有其在油、气勘探和评价方面的意义。从地化录井的原理出发,建立了热解地化录井在生油岩、储集岩方面的评价技术。同时依据多个参数之间的联系,建立起定量解释模版,克服了单个参数解释的不足,提高油气解释精度。依据热解气相色谱录井理论,总结了其在油、气、水层的特征,为油气勘探提供依据。

There are many geochemical logging parameters and each parameter has its significance of petroleum exploration and evaluation. This paper establishes the evaluation technique of pyrolysis geochemical logging in oil source rock and reservoir rock based on the geochemical logging theory. At the same time, we establish a quantitative interpretation template according to the multiple parameters relations, which overcomes the interpretation deficiency of single parameter and improves the interpretation precision. On the basis of the logging theoretical technology of pyrolysis gas chromatography, we summarize its characteristics in the oil, gas and water layers. That provides an evidence for petroleum exploration.
