摘要： 利用储集层地球化学录井资料定量评价原油性质对于现场快速评价油气层工业价值,及时采取合理的油层保护措施具有重要意义。以塔里木盆地储集层岩石热解资料、中途测试和完井试油成果为依据,探讨了利用三峰岩石热解资料评价原油性质的方法,利用产油率指数建立原油密度和粘度的统计方程,采用亮点指数判别原油类型,取得了较好效果。这一研究成果为充分发挥地化录井的技术优势并为塔里木盆地的油气勘探提供了可靠依据。

Abstract: Using geochemical log data from reservoirs to quantitatively evaluate crude oil properties can be as a guide for field quick evaluation of commercial value of reservoir rocks and timely taking reasonable measures in reservoir protection. The method for evaluating crude oil properties by utilizing Sanfeng petrologic pyrolysis data, statistical equations for establishing crude density and viscosity by production rate index and distinguishing crude oil types by bright spot index were discussed on the basis of Tarim basin's reservoir petrologic pyrolysis data, drill-stem testing and completion well test results. Good effectiveness was achieved by them, which offers reliable basis for making full use of the technical advantage of geochemical log and for hydrocarbon prospecting in Tarim basin.
