| 摘 要： | 本文根据气井防砂砾石的粒径构成特征及完井防砂砾石充填是多种粒径砾石混合而成的堆积碎散性特征,通过剖析高压充填条件下混合粒径砾石堆积的排列结构,建立砾石堆积孔喉直径结构理论模型,推导出计算砾石堆积孔喉直径尺寸的公式。同时,通过理论计算分析了砾石颗粒的粒径比对砾石堆积孔喉直径尺寸的定量影响规律,为水合物试采井防砂砾石粒径的选择提供了理论依据。

| Abstract: | According to the characteristics of gas well sand gravel and particle size composition of sand control completion gravel pack is accumulation of a variety of particle size of gravel mixture of broken characteristics, through the analysis under the condition of high pressure filling mixed particle size of gravel pile arrangement structure, establish a gravel pile diameter pore throat structure theoretical model, deduce the calculation formula of gravel pile up pore diameter size. Gravel particles were analyzed at the same time, through the theoretical calculation of the size ratio on gravel pile pore diameter size of the quantitative influence law for hydrate test well sand control provides theoretical evidence for the selection of gravel size. |
