非常规油气“甜点”预测新技术

New “Sweet Spot” Predicting Technology of Unconventional Oil and Gas

在当前经济技术条件下如何有效开发非常规油气资源,国外油公司在地质、物探、测井等各大领域都研发了针对性的新技术、新方法,特别是预测"甜点"的技术,具体介绍了页岩"甜点"地质综合识别技术、页岩资源综合评价方法、人工神经网络法、GeoSphere油藏随钻测绘服务系统、核磁共振因子分析技术、OVT地震资料叠前地震道处理技术、测井数据函数主成分分析法、油气微生物监测和"4G"勘查模型监测技术、应用高分辨率层序地层学识别煤层气甜点技术、TIER量化法等新技术进展与应用效果。这些技术有的已经成熟,有的还需进一步完善,我们的企业可在非常规油气资源勘探开发工程中择其善者而从之。

As for how to effectively develop unconventional oil and gas resources under the current economic and technological conditions, foreign oil companies have developed some new technologies and new methods in the geological, geophysical and logging areas, the “sweet spot” predicting technology in particular. This article introduces a series of new technologies and application results, such as integrated technology for geological identification of shale “sweet spot”, integrated method for evaluation of shale resources, artifcial neural network method, GeoSphere reservoir mapping-while-drilling service system, NMR factor analysis technology, Pre-Stack gather conditioning techniques of OVT seismic data, fPCA method using well log data, geo-microbial hydrocarbon detection and 4G exploration model technique, technology for identifcation of CBM sweet spot through application of high-resolute sequential stratigraphy, and TIER quantitative method. Some of those technologies are already while the others are under perfection. The enterprises can select the appropriate methods for their exploration and development of unconventional oil and gas resources.
