微地震监测在地震地质工程一体化中的应用

Microseismic monitoring in seismic and geology integration

随着全球经济发展对油气需求的持续增长以及勘探开发技术的不断提高,非常规油气藏正逐步成为接替资源及勘探开发热点。在储层甜点预测技术、水平井钻完井技术、储层改造增产技术以及微地震监测技术日渐成熟的背景下,中国石油集团东方地球物理公司在理论研究与实际应用中总结出一套涉及多学科的综合地震地质工程一体化技术思路。本文主要描述了在四川盆地昭通页岩气示范区等地开展的基于微地震监测技术的地震地质工程一体化实践,取得了良好的应用效果,同时也证明该套技术具有推广价值。

With the increase of oil and gas demands of global economic development and the exploration technology progress,unconventional oil and gas resources have gradually become now an alternative resource and a hotspot in the exploration and development all over the world.China has abundant unconventional oil and gas resources.There are large zones of unconventional oil reservoirs in many basins such as Sichuan Basin,Songliao Basin,and Junggar Basin,and their peripheral regions,where shale and tight sands provide favorable geologic conditions for reservoir formation.Based on the developments of reservoir sweet-spot prediction,horizontal well drilling and completion,reservoir stimulation,and microseismic monitoring,our research team has summarized a strategy of seismic and geology integration.This involves many disciplines and has been already applied in the field.The paper presents an example in Sichuan Basin.
