摘要
深水钻井下喷射导管的钻井参数与陆地及浅水钻井存在较大不同。为了模拟喷射下导管过程,为深水钻井喷射下导管作业参数计算提供试验数据,根据深水喷射下导管的特点,以其工具及组合形式为基础,结合土力学基础理论,研制了深水钻井喷射下导管模拟试验装置。该装置主要由土箱、管柱系统、起吊系统、循环系统、加载系统和测量系统组成,可以模拟喷射下导管全过程,通过改变模拟试验中的喷射参数和岩土性质,并对导管的下入速率、承载能力(横向应变、竖向应变及承载能力)进行测量,进而可以研究深水钻井导管喷射作业过程当中,不同岩土性质条件下的喷射参数与导管下入速度和承载能力之间的相互关系和影响规律,建立导管作业参数优化设计方法,为深水油气钻探中导管喷射下入的优化设计提供参考。
Conductor jets running in deepwater drilling have different drilling parameters from that of land or shallow water drilling .In order to simulate the deepwater conductor jet running process ,and pro‐vide experimental data for calculating operation parameter of conductor jetting running ,a new simulating device for conductor jet running in deepwater drilling has been developed according to characteristics of deepwater conductor jet running ,combined basic theory of soil mechanics with the form of running tool as‐sembly .This device mainly consists of a soil box ,pipe string ,hoist ,circulating loop ,loading and measuring systems .It can simulate the w hole process of conductor jet running .By changing the jet parameters and the geotechnical properties in the simulation test ,the running speed of the conductor and bearing capacity ,in‐cluding the horizontal and vertical strain as well as the bearing capacity ,can be measured ,so as to study the relationship among jet parameters ,the conductor running speed and bearing capacity during the course of conductor jet running for deepwater drilling under different geotechnical properties ,develop a optimization design for conductor operation parameters ,and provide a reference for the optimization design of conductor jets running in deepwater drilling of oil and gas well .
