| 摘 要： | 林4-36X井是二连油田低压区块上的一口开发井,目的层段压力系数0.6～0.9,钻井过程中在油层段1372.4 m和1485.3 m处发生漏失,井漏时钻井液密度1.19 g/cm3;在发生井漏的同时,也存在着油水外浸.在井温低、水泥用量小的情况下,采用低密度防漏防窜水泥浆体系固井,通过降低水泥浆密度并在水泥中加入弹性防漏堵漏材料,提高水泥浆的防窜性能等技术措施进行固井,施工作业顺利,电测固井质量优质. |
| 关 键 词： | 林4-36X井 固井 低密度水泥浆 防漏 防窜 |

| Abstract: | LIN 4-36X is a development well located in the low-pressure block of Erlian Oilfield. Pressure coefficient of its target layer is between 0. 3 to 0. 4. In the course of drilling, leakage happened in the positions of 1372. 4m and 1485. 3 m. The fluid density came to 1.19 g/cm3 when leakage and water soak happened. In that condition, low-density drilling fluid for leak protection and water shutoff was used for cementing and the added flexible leak-proof material made the cementing operation become smooth. Electrical logging results showed that the cementing was of high quality. |
| Keywords: | LIN 4-36X Well cementing low-density drilling fluid leak protection anti-channeling |
