CBIL测井在火成岩地层中的应用

Application of CBIL to Igneous Rocks

魏涛，田洪，赵立新．ＣＢＩＬ测井在火成岩地层中的应用．测井技术，１９９７，２１（１）：３２～３８井周声波成象测井（ＣＢＩＬ）与岩心描述有着良好的一致性。在火成岩地层中，它清晰地显示裂缝、孔洞以及风化残积的砾石。经过人机联合处理分析，可进一步确定地层储集类型、裂缝产状、裂缝密度、裂缝张开性和张开缝的主要发育方向；确定地质方面无法弄清的古潜山顶部地层的层位。另外。

There is a good consistency between Circumferential Borehole Imaging Log and core description. In the igneous rock formation, CBIL shows fractures, vugs and weathered residual gravel clearly. Interactive processing and analysis can determine reservoir types ,fracture dip and orientation, fracture density, fracture opening and the main direction of open fractures. Horizon of the top of buried hills, which geologists can not make clear, can also be determined. In addition,the straightforward image of hydrofractures also shows the directions of in situ rock stress.
