川南地区页岩气测井技术系列研究

Study on Shale Gas Logging Technology Series in Southern Sichuan

摘要: 测井在页岩气勘探开发过程中发挥着至关重要的作用，经济合理的测井系列将直接关系到储层的综合评价，并对一个地区的勘探开发效果产生重要影响，同时也间接决定后期资金的投入。目前，川南威远–永川地区页岩气仍处于勘探开发阶段，勘探阶段丰富的测井资料能较好地支撑储层精细评价；随着开发阶段测井项目逐渐减少后，有限测井资料不足以满足地质工程评价需求的矛盾日益突出。本文从各类页岩气测井项目的用途出发，结合实际案例开展系列优选方案研究，总结出适合川南地区页岩气勘探开发的测井系列，期望为后期施工提供参考。

Abstract: Logging plays a vital role in the exploration and development of shale gas. Economical and rea-sonable logging series will directly affect the comprehensive evaluation of the reservoir, have an important impact on the exploration and development effect of a region, and indirectly determine the investment in the later stage. At present, the shale gas in Weiyuan-Yongchuan area in southern Sichuan is still in the exploration and development stage, and the rich logging data in the explora-tion stage can better support the fine reservoir evaluation; With the gradual reduction of logging projects in the development stage, the contradiction that the limited logging data is not enough to meet the needs of geological engineering evaluation has become increasingly prominent. This paper starts from the purpose of various shale gas logging projects, carries out a series of optimization scheme studies in combination with actual cases, summarizes the logging series suitable for shale gas exploration and development in southern Sichuan, and hopes to provide reference for later construction.
