Geophysical well-log evaluation in the era of unconventional hydrocarbon resources (mainly tight oil and gas, shale oil and gas) is complicated and challenging. This review aims to fill this gap between well-log evaluation and unconventional hydrocarbon resources by characterizing the source rock property, reservoir property and engineering property using petrophysical well logs. The advanced well-log series used for unconventional oil and gas evaluation include nuclear magnetic resonance (NMR) log, image logs, array acoustic logs, elemental capture spectroscopy (ECS) and LithoScanner logs. The source rock property in terms of total organic carbon content is predicted using conventional logs and LithoScanner log. Then petrophysical parameters including porosity, permeability and oil saturation are calculated, and the appearance of natural fracture is predicted from conventional, sonic logs, image logs and NMR logs. Additionally, the reservoir property is evaluated to optimize the favorable layers with high hydrocarbon bearing property and productivity. Brittleness index as well as in situ stress direction and magnitudes are characterized by the comprehensive use of density, sonic log, ECS log and image logs. Then, the engineering property (high brittleness index but low horizontal stress difference) is evaluated to screen out the prospected layers for hydraulic fracturing. The internal relationships between the three types of properties are unraveled, and the geological and engineering sweet spots are optimized by integrating lithology, reservoir quality, hydrocarbon bearing property, source rock property, brittleness and in situ stress magnitude and direction. This multidisciplinary approach provides a comprehensive method for optimizing sweet spots in unconventional play, and will support petroleum geoscientists’ and engineers’ decisions in exploration and exploitation of unconventional hydrocarbon resources.

非常规油气资源（主要为致密油气、页岩油气）时代的地球物理测井评价复杂而具有挑战性。本综述旨在通过利用岩石物理测井表征烃源岩性质、储层性质和工程性质，填补测井评价与非常规油气资源之间的空白。用于非常规油气评价的先进测井系列包括核磁共振 (NMR) 测井、图像测井、阵列声学测井、元素捕获光谱 (ECS) 和 LithoScanner 测井。使用常规测井和 LithoScanner 测井预测烃源岩总有机碳含量。然后计算孔隙度、渗透率和含油饱和度等岩石物理参数，通过常规、声波测井、图像测井和核磁共振测井预测天然裂缝的出现。此外，还对储层物性进行评价，以优化具有高含烃性和产能的有利层级。综合利用密度、声波测井、ECS测井和图像测井来表征脆性指数以及地应力方向和大小。然后对工程性质（脆性指数高，水平应力差低）进行评价，筛选出水力压裂的前景层。理清三类性质的内在联系，综合岩性、储层质量、含烃性质、烃源岩性质、脆性和原位应力大小和方向。这种多学科方法提供了一种优化非常规油气最佳位置的综合方法，并将支持石油地球科学家和工程师在非常规油气资源勘探和开发中的决策。
