AI Technical Summary
Technical Problem
Existing technologies do not fully consider the movement characteristics and perforation similarity of downhole television in downhole video transmission, resulting in low accuracy of perforation area measurement and affecting the accuracy of fracturing effect evaluation.
Method used
By analyzing the connected component features in video frames, we construct the perforation confidence and cross-perforation matching risk value, dynamically adjust the merange parameter of the HEVC algorithm, and optimize the encoding and transmission process.
Benefits of technology
It improves the accuracy of perforation area measurement and fracturing effect evaluation, and ensures the stability of code transmission and the integrity of perforation boundary contours.

Abstract
本申请涉及图像传输技术领域，具体涉及一种油气井的压裂改造效果可视化评价方法，该方法包括：实时采集油气井测量过程中的视频帧和电缆长度；提取视频帧中的分析帧；基于各分析帧中各连通域的边缘特征、灰度特征和形状特征，获取射孔连通域；基于各分析帧中射孔连通域的数量，判断是否采用默认merange参数进行编码传输；若不采用，则基于各分析帧内射孔的密集程度、差异程度和帧间位移，以及所述电缆长度，对各分析帧的默认merange参数进行优化，进而对各分析帧所在分析区间的所有视频帧进行编码传输；基于传输后的各视频帧对压裂改造效果进行评价。本申请通过自适应地调节merange参数，提升了压裂改造效果评价的准确性。
