水力喷射径向水平钻井水力参数设计
|
摘要
基于流体力学理论分析,建立了水力喷射径向水平钻井循环系统沿程压耗的计算模型。结合现场工艺过程,以最大水力钻头压降为优化目标,建立了水力喷射径向水平钻井水力参数的优化模型,提出了径向水平钻井水力参数的设计方法。结合具体工程实例,验证了计算模型及设计方法的正确性,分析了各参数的敏感性。结果表明,最优排量及最大钻头压降随着连续油管、高压软管的内径和最大泵压允值的增加而增大,而随着钻井液黏度的增大而减小。该方法为径向水平钻井的水力参数设计提供了理论依据。
Based on the theoretical analysis of fluid mechanics, the calculation model of pressure loss of circulating system for radial horizontal drilling by hydrajet was established. Combined with field technology, the optimization model of the hydraulic parameters of hydraulic jetting radial horizontal drilling was established and the design method of hydraulic parameters of radial horizontal drilling was proposed to optimize the pressure drop of the maximum hydraulic bit. Combined with specific project case, the validity of calculation model and design method was verified and the sensitivity of each parameter was analyzed. The results reveal that the optimal pump rate and the pressure drop of the maximum bit increase with the increase of the inner diameters of coiled tubing and high-pressure hose as well as the permissible value of the maximum pump pressure, but decrease with the increase of the viscosity of drilling fluids. This method provides a theoretical basis for the design of hydraulic parameters of radial horizontal drilling.
