地震勘探:页岩气资源评价的好帮手

Seismic exploration:a good helper for shale gas resource evaluation

随着能源需求的增长,页岩气作为一种重要的新能源资源占有举足轻重的地位。然而,目前我国对页岩气的勘探开发基本处于资源评价、有利区优选和早期开发阶段,技术手段还不成熟。地震勘探技术是一种非常有效的勘探方法,可以凭借较低的成本在不破坏地下结构的情况下获取高精度、高分辨率地质信息,达到降本增效的目标并提高勘探成功率。在页岩气资源评价环节,地震勘探技术在页岩气储层层位解释、页岩“甜点区”预测、页岩含气性检测、页岩目的层裂缝预测等方面具有较为成熟的应用。随着地震勘探技术的不断进步,地震勘探技术将会在页岩气资源评价和开发中发挥更加重要的作用。

With the growth of energy demand,shale gas occupies a pivotal position as an important new energy resource.However,at present,the exploration and development of shale gas in China is basically at the stage of resource evaluation,favourable area selection and early development,and the technical methods are not yet mature.Seismic exploration is a very effective exploration method,which can obtain high accuracy and high definition geological information without destroying the geological structure at a low cost,and increasing the exploration success rate.In shale gas resource evaluation,seismic exploration technology has mature applications in shale gas reservoir interpretation,shale“Sweet Area”prediction,shale gas-bearing capacity.and shale target layer fracture prediction.With the continuous progress of seismic exploration,it will play a more important role in the evaluation and development of shale gas resources.
