| 中文摘要: |
| 地震勘探探测范围广、空间尺度大，数据采集、处理、解释体系完善，资料运用率高，但纵向分辨率低。声波远探测可实现井周数十米范围内的异常体探测，克服了常规测井方法探测深度浅的局限，具有很高的纵向、周向、径向分辨率，但偶极横波远探测具有180°方位不确定性，径向探测范围不及地震勘探。本研究将两者优势结合，通过对缝洞型地质异常体远探测和地震响应特征进行综合分析，约束远探测方位解释结果，精细刻画地质异常体形态及发育情况，完善远探测测井的横向延伸信息，有效提高远探测解释的精准度，最终形成声波远探测测井与地震一体化缝洞综合评价技术，提升缝洞油气藏钻遇率和开发效率。在塔河等缝洞发育地区进行应用，实现多尺度、全方位和高精度的地质异常体描述与解释，为解决油气勘探过程中由于地震分辨率不足造成的脱靶等现象提供了新的思路。 |
| 英文摘要: |
| Seismic exploration has a wide investigation scope and a large spatial scale. Its data acquistion, processing and interpretaion system are complete and own a high utilization rate, but its vertical resolution is low. Acoustic remote detection logging is capable of detecting anomalous bodies that exist tens of meters away from the borehole, which overcome the limitation of shallow investigation depth for conventional logging and has a high resolution in vertical, circumferential and radial directions, but dipole shear wave remote dection has 180 degree orientional ambiguity, and the radial detection range is less than that of seismic exploration. This study combines the advantages of both, and through the comprehensive analysis of the remote detection and seismic response characteristics of the fracture-cavity geological anomalies, constrains the remote detection orientional interpretation results, finely characterizes the morphology and development of the geological anomalies, improves the lateral extension information of the remote detection logs, effectively improves the accuracy of the remote detection interpretation, and finally forms a comprehensive evaluation technology of acoustic remote detection logs and seismic integrated seamhole, which improves the drilling hit probability and development efficiency of the seamhole oil and gas reservoir. The result is a comprehensive evaluation technology that integrates acoustic remote logging and seismic to improve the drilling encounter rate and development efficiency of seamhole reservoirs. With the application in Tahe Area, etc., description and interpretation of multi-scale, all-round and high-precision for geological anomalous body is developed, which provides a new idea to avoid off-target caused by insufficient seismic resolution in oil and gas exploration. |
