【摘要】：巖石熱物理性質的基礎研究大致經(jīng)歷了4個階段,已廣泛應用于巖石圈熱結構、沉積盆地熱演化史、巖土工程、地熱等領域,近年來在油氣領域的科學問題上備受關注。在歸納總結巖石熱物理性質當前研究進展的基礎上,對未來的發(fā)展趨勢進行了展望。熱導率是表征巖石熱物理性質最重要的參數(shù),其獲取方法以室內實驗室測量為主,測量方法有穩(wěn)態(tài)法和非穩(wěn)態(tài)法兩大類。此外還發(fā)展了一些基于圓柱形熱源探管、圓盤形熱源探管、球形熱源探管的原位點測方法和基于數(shù)理統(tǒng)計的預測方法和模型。學者們通過大量實驗探討了巖石熱導率參數(shù)與其他物理性質之間的內在關系,并以火山巖、碳酸鹽巖、碎屑巖等常見巖石實驗結果驗證其存在的一般規(guī)律。研究表明巖石的熱導率受多種因素影響,巖石學特征是其中最重要的因素,孔隙度、含流體性質、聲學特性也與之密切相關,同時會受到溫度、壓力、各向異性的影響�？v觀巖石熱物理性質的研究現(xiàn)狀,認為在油氣領域有以下發(fā)展趨勢:首先,頁巖氣作為目前油氣勘探的熱點,其形成機理和成藏過程受頁巖熱物理性質的控制,但頁巖熱導率與有機孔、有機碳含量、含氣量、可壓裂特征間的關系還未可知,因此探索含氣頁巖的熱物理性質是一大研究方向。其次,大數(shù)據(jù)研究是大勢所趨,盡管巖石熱學參數(shù)的數(shù)據(jù)庫在不斷擴大,但要想得到準確的巖石原位熱導率大數(shù)據(jù)庫,在井中完成熱導率原位連續(xù)測量則是最好的方法。因此發(fā)展基于巖石熱物理性質的測井方法原理和儀器研究是另一大發(fā)展趨勢。
[Abstract]:The basic research on the thermal physical properties of rocks has been widely used in the fields of lithospheric thermal structure, thermal evolution history of sedimentary basins, geotechnical engineering, geothermal, and so on. In recent years, it has attracted much attention in the field of oil and gas. On the basis of summing up the current research progress of rock thermal physical properties, the future development trend is prospected. Thermal conductivity is the most important parameter to characterize the thermophysical properties of rock. The main methods for obtaining thermal conductivity are indoor laboratory measurements. There are two kinds of measurement methods: steady-state method and unsteady-state method. In addition, some in situ point measurement methods based on cylindrical heat source probe, disk heat source probe and spherical heat source probe are developed, as well as prediction methods and models based on mathematical statistics. The relationship between thermal conductivity parameters and other physical properties of rocks is discussed by a large number of experiments, and the general laws of their existence are verified by the experimental results of volcanic rocks, carbonate rocks and clastic rocks. The results show that the thermal conductivity of rock is affected by many factors, among which petrological characteristics are the most important. Porosity, fluid properties and acoustic properties are closely related to the thermal conductivity of rock, and are also affected by temperature, pressure and anisotropy. According to the present research situation of petrophysical properties of rocks, it is considered that there are the following development trends in the field of oil and gas: firstly, shale gas is a hot spot in oil and gas exploration at present, and its formation mechanism and accumulation process are controlled by the thermal physical properties of shale. However, the relationship between the thermal conductivity of shale and organic pores, organic carbon content, gas content and fracturing characteristics is not known, so it is a research direction to explore the thermo-physical properties of gas-bearing shale. Secondly, the research of big data is the trend of the times. Although the database of thermal parameters of rock is expanding continuously, the best method is to complete the in-situ continuous measurement of thermal conductivity in wells in order to obtain an accurate database of in-situ thermal conductivity of rock. Therefore, the development of logging methods and tools based on the thermal physical properties of rock is another trend.
