摘　　要：L型水平井及无杆排采工艺是实现煤层气高产稳产和降低成本的重要技术,无杆泵动力液箱缺液造成煤层气井排采不连续,造成产量波动和储层伤害。为了解决上述问题,研制了动力液箱液位自动报警装置,现场应用效果较好。L-type horizontal wells and no-rod drainage technology are important technologies to realize high and stable production and cost reduction of Coalbed Methane. The lack of fluid in the no-rod pump power fluid tank results in discontinuity of CBM well drainage and production, fluctuation of production and damage of reservoir. In order to solve the above problems, an automatic alarm device of liquid level of power tank was developed and the performance of field application is perfect.
