摘要
随着非常规油气资源评价工作的深入开展,非常规油气资源经济评价成为油气资源评价工作中越来越重要的一部分。针对非常规油气资源的特点,提出了非常规油气经济评价的目的性、可比性二原则,建立了非常油气资源经济性评价的内容、方法、经济性指标及标准;以高、中、低3种油价情景,探讨了四川盆地页岩气的资源经济性定性和定量评价模式,建立了四川盆地页岩气资源经济性评价工作流程和关键指标体系,指出四川盆地页岩气资源具有较好的经济性,存在3个一类高效经济区、4个二级次有效经济区、2个三级低效页岩气资源区。研究结果对建立科学、有效的非常规油气资源经济评价方法、指标体系、经济评价结果定量化和有利区带层系优选将起到规范和推动作用。
With in-depth development of unconventional oil and gas resource evaluation, economic assess- ment is becoming a more and more important part of oil and gas resource evaluation.Aiming at the charac- teristics of unconventional oil and gas resources, in this paper, we proposed two principles, purposiveness and comparability,and established the evaluation content, method, economic indexes and standards for eco- nomic assessment of unconventional oil and gas resources.Under the conditions of high, medium and low oil prices respectively, we discussed the qualitative and quantitative economic evaluation models, and estab- lished the work process and key indexes system of economic assessment for shale gas resources in the Si chuan Basin.We pointed out that the shale gas resources in the Sichuan Basin is quite economic,and there are three class-Ⅰ high-economic areas, four class-Ⅱ sub-economic areas, and two class-Ⅲ low-economic shale gas resource areas.The research results will standardize and promote the establishment of scientific and effective method and index system for unconventional oil and gas resource economic assessment, quan- tification of economic assessment results, and the selection of favorable areas and layers.
