中文摘要:针对油气及非常规油气、科学钻探中，砂质泥岩和砂泥岩互层钻进效率低、钻头寿命短的难题，通过齿形金刚石复合片与圆形复合片的交错布置，研制的新型高效耐冲击复合片取心钻头在新疆吉木萨尔油田36-4井页岩油芦草沟组进行了试验研究。结果表明：研制的新型高效耐冲击复合片取心钻头机械钻速较其他钻头提高了2.4~3.1倍，取得了良好的社会经济效益。

Development and application of high-efficiency and impact-resistance PDC core bits
Abstract:In oil and gas， unconventional oil and gas， and scientific drilling， drilling efficiency in sandy mudstone， and interbedded sand and mudstone is low， and the bit service life is short. Through the staggered arrangement of tooth shaped PDC and circular PDC， a new high-efficiency and impact-resistance PDC core bit was developed and tested in Lucaogou Formation of shale in Well 36-4 of Jimusaer Oilfield， Xinjiang. The results showed that the penetration rate of the new type of high-efficiency and impact-resistance PDC core bit was 2.4 to 3.1 times higher than that of other bits， and good social and economic benefits have been achieved.
