地层中与油气扩散有关的热释光变化规律的研究

This program is developing and continued of previous item "Mechanism of detecting potential oil field using thermoluminescence(TL) of ground soil (pass No.49572127) ". It laid emphasis on to research the space relation between TL and a reserve of oil and gas. It is the first time exploring for oil on well bottom using TL. Though combining the flat surface (on ground watch) with the depth (on well bottom), the correlation of TL and an oil field is initially revealed in 3-D stereo space. The petroleum migration is confirmed under indoor simulated test and natural conditions. The radioisotopes migration is found with present determination or history records. It is discovered that accumulative effects conduce to differentiate between efficacious signal and background noise. And testing the feasibility using optical luminescence to petroleum exploration.

利用地表土反映的平面热释光异常区探测地下油气藏，是油气勘探研究只的新思路。现已取得的初步理论模式与实践，是进一步深入研究的良好基础。本项目申请，重点拟研究热释光在埋深方向上的变化规律，结合上一课题研究成果，探讨油气扩散在三维立体空间的影响，以及热释光直接找油的可能性。它不仅具有较高的学术理论研究意义，而且具有明显的生产应用价值，是一项实用性很强的应用基础研究。.
