【摘要】：針對(duì)隔水導(dǎo)管穿刺鞋打樁作業(yè)中出現(xiàn)的溜樁、破巖能力差等問題,研發(fā)了一種新型國(guó)產(chǎn)隔水導(dǎo)管穿刺鞋,采用圓柱形管體防止歪樁,管體外部焊接加強(qiáng)筋提高強(qiáng)度,底部有線形結(jié)構(gòu)合金齒用以破裂堅(jiān)硬巖層。ANSYS數(shù)值模擬分析表明,新型國(guó)產(chǎn)隔水導(dǎo)管穿刺鞋具有較好的貫入能力、抗壓能力及抗外擠能力,其性能指標(biāo)具有較大的安全余量,可滿足現(xiàn)場(chǎng)應(yīng)用要求。新型國(guó)產(chǎn)隔水導(dǎo)管穿刺鞋已在南海西部某區(qū)塊16口井的隔水導(dǎo)管打樁作業(yè)中取得成功應(yīng)用,與周邊油田打樁作業(yè)相比平均每錘進(jìn)尺提高約28%,作業(yè)效率提高約15%,具有良好的應(yīng)用效果和可推廣價(jià)值。
[Abstract]:In order to solve the problems of shoe-passing and poor rock breaking ability, a new type of home-made piercing shoe is developed, in which the cylindrical tube body is used to prevent the pile from tilting, and the external welding reinforcement is strengthened to improve the strength of the shoe. Numerical simulation analysis of linear structure alloy teeth at the bottom for breaking hard rock layer. ANSYS shows that the new type of piercing shoes made in China have better penetration ability, compression resistance and external extrusion resistance, and their performance indexes have greater safety margin. It can meet the requirements of field application. The new type of waterproof pipe piercing shoes have been successfully used in the piling operation of 16 wells in a block in the west of the South China Sea. Compared with the piling operation in the surrounding oilfields, the average stroke advance is about 28% and the working efficiency is increased about 15%, which has good application effect and can be popularized.
