| 中文摘要:酸化增产技术是提高油田产量的有效措施，是开发油气层的重要手段。HD-39B地热井完井后，试水效果不理想，通过分析其测井综合成果，并结合地层情况，采用了酸化增产工艺，最终成功扩大裂隙，有效沟通了热储通道，出水量由5.4 m3 /h增加到80.83 m3 /h，井口水温由50 ℃增加到72 ℃，成为一口优质合格井。HD-39B地热井的应用实践证明，油田上使用的酸化增产技术同样适用于碳酸盐基岩裂隙地热井，可根据地热井实况及岩性特征，在类似地热施工中予以推广。 |

| Abstract:Acidizing stimulation technology is an effective measure to improve oil production and an important means of developing oil and gas bearing formation. The water test is not ideal, after the completion of HD-39B geothermal well. The acidizing technology was used based on the analysis on the comprehensive logging data and combined with the formation conditions, cracks were extended and geothermal reservoir channels were linked up, HD-39B turned to be of high-quality with the water yield being from 5.4m3 /h to 80.83m3 /h, wellhead water temperature from 50℃ to 72℃. The application practice shows that the acidizing technology is also suitable for carbonate bedrock fracture geothermal well, which can be popularized in the similar geothermal construction according to the actual conditions and the lithologic characters. |
