页岩小层水平井对比及其构造三维可视化表征

页岩气建产区是以平台+水平井的井工厂模式运营的，利用水平井开展页岩小层对比及其结构与构造建模，在目前还是一项亟待攻关的技术难题。在解析页岩小层结构特征基础上，建立了页岩小层分层模式和水平井测井多井三维可视化对比方法，依靠井震结合，实现了页岩小层结构与层面构造的三维建模，形成了井工厂模式下页岩气建产区小层结构与层面构造三维可视化表征新技术。成功完成了四川盆地W页岩气田某典型建产区6个页岩小层分层模式的建立、水平井多井可视化对比，以及页岩小层结构与7个小层层面构造模型的建立。在证实该技术实用性及可靠性的同时，还为研究区后期的精细化生产管理提供了构造模型基础。

Shale Layer Correlation of Horizontal Wells and Their 3D Visual Characterization

Till now, it is still a technical problem to build the single-layer architecture and surface structure models for a shale gas-production area under the horizontal well factory pattern. Focusing on the single-layer shale, We analyze the structure characteristics of the single shale layers, establish the shale layer correlation model, develop the method of 3D visual multi-well correlation technology for the single-layer shale by using horizontal well logging, carry out the division and correlation of the single-layer shale, and complete the 3D single-layer architecture and surface structure models by relying on thecoupling method. A new method of 3D visual characterization of the single-layer architectures and surface structures under the horizontal well factory pattern in the shale gas-production area is finally established. By using this method, the establishment of 6 shale layer models, the visual shale layer correlation of horizontal wells and the establishment of the single layer structure and 7 single layer surface structural models in one shale gas-production area of the shale gas field W have been successfully completed, which not only proves the practicability and reliability of this method, but also provides the structural models for fine production management in the later stage of the study area.
