| 中文摘要:为了进一步提高塔里木盆地中上部地层钻速，依据塔里木盆地的钻井地质特点，本文开展了大排量超高压喷射优快钻井技术研究。依据该地区钻井地质环境，提出来大排量适当钻头压降的超高压喷射优快钻井技术方案，并据此优化升级钻井装备，以满足大排量超高压喷射钻井技术的需求。依据试验方案，对排量和钻头压降两个核心参数进行了优化设计，并开发了水力学计算软件，在此基础上优化了钻进参数和钻井液性能参数。现场应用5口井，与常规技术相比，35MPa高压喷射钻井钻速可提高50%~260%，钻井周期可下降38~58%，同时该技术还具有明显的防阻卡效果，井身质量较好，提速提效显著。 |

| Abstract:In order to enhance penetrate seed bettly, super high pressure jet drilling technology with high discharge is researched.Based on drilling geologic environment of Tarim basin, the super high pressure jet drilling scheme with high discharge & adequate bit pressure drop is proposed, and drilling rig is upgraded,to meet need for high pressure jet drilling scheme with high discharge. Based on drilling scheme, discharge capacity and bit pressure drop is optimized, and hydraulic compute software is programmed. Based on which, drilling parameters and drilling fluid performance parameters are also optmized. The result is used in five wells, and comparaed with conventional technology, penetartion rate with super high pressure jet drilling technology can be enhanced by 50%~260%，and drilling time can be reduced by 38%~58%. Drilling sticking problem can also be reduced obviously, and wellbore quality is better, as well as penetration rate and drilling efficiency are obviously enhanced. |
