1.非常规油气资源空间分布预测技术有效规避勘探风险纯随机模拟法和资源密度网格预测法等5种评价新方法相继推出。纯随机模拟法细化了评价地区和评价过程,针对已钻井区和未钻井区采取不同的评价方法、数学模型和评价步骤,大大提高了非常规油气资源丰度与空间分布预测的精确度。资源密度网格预测法针对连续型油气区带资源评价,解决了传统类比法没有考虑不同评价单元最终可采储量的空间关系等方面存在的问题,可以有效评价非常规油气资源潜力,预测油气资源在空间的分布。2.深层油气“补给”论研究获得重要进展
1. Unconventional oil and gas spatial distribution forecasting technology to effectively avoid exploration risk Pure stochastic simulation method and resource density grid forecasting method five kinds of evaluation methods have been introduced. The pure stochastic simulation method is used to refine the evaluation area and evaluation process. Different assessment methods, mathematical models and evaluation steps are taken for the areas that have been drilled or not drilled, which greatly improves the accuracy of unconventional oil and gas resource abundance and spatial distribution prediction. The resource density grid forecasting method solves the problems existing in the traditional analogy method without considering the spatial relationship of the final recoverable reserves of different evaluation units. It can effectively evaluate the potential of unconventional oil and gas resources and predict the oil and gas resources Distribution in space. 2. Deep research on oil and gas “supply ” made significant progress
