Experiment Study on Effect of Cuttings on Foam Drilling Fluid Properties

Abstract:

Experiment study was made on the effect of cuttings type, size and concentration on foaming and half-life of foaming agent so as to guide the practical foam application for making full use of it in the actual drilling. After the performance improvement for years, foaming performance and half-time of ADF-3 foaming is improved, it is widely used in water well and gas discharge well construction with its unique function in DTH drill.
