摘　　要：在堵漏过程中,对堵漏材料和堵漏浆配方的优选是决定堵漏成功的关键。为了能在现场对堵漏进行评价,研制出了BDY-1便携式堵漏仪。该堵漏仪主要由不锈钢钢柱,圆钢,压力表等加工而成。该堵漏仪体积小、重量轻、价格低,仅为国产堵漏仪的1/20。试验结果表明,BDY-1便携式堵漏仪操作简便,可快速对堵漏材料进行评价并筛选出堵漏配方;数据重复性好,准确可靠,能达到进口或国产堵漏仪的水平;在模拟漏层选定后,可采用多套压力梯度,对堵漏浆封堵效果进行评价;在压力梯度选定后,可评价堵漏浆对不同类型漏层的封堵效果;如果扩大压力范围,可对封堵后的漏层进行破裂试验,从而确定合理的钻井施工参数;适用现场操作和应用。The key for a successful lost circulation control depends on the optimization and selection of lost circulation materials and formulation of plugging fluids. Lost circulation evaluation devices used in the past are inconvenient due to their large sizes, high costs and long evaluation time. A portable device BDY-1 is developed, which is made up of a stainless steel post, round steel and a pressure gauge. This portable device has such advantages as small size and light weight, and its price is only 1/20 of the conventional one. It is simple and suitable for on-site use, and has good data repeatability and reliability.
