Problems solved by technology

Usually, the development of fractures and broken zones will form lost zones. During the drilling process, drilling fluid will leak from these lost zones, which will affect the normal drilling construction.
Especially in large-distance horizontal directional drilling, problems such as drilling fluid loss and slurry emission increase the difficulty of drilling construction
However, in the existing drilling technology, the leakage prevention and plugging effect of the drilling fluid is poor, which reduces the drilling efficiency.

Abstract

The invention discloses a foaming agent, a circulating microfoam drilling fluid and a drilling process. The foaming agent includes 30% sodium dodecylbenzenesulfonate ABS and 70% sodium dodecylsulfate SDS. The recyclable microfoam drilling fluid is 4%-5% pre-hydrated bentonite slurry, adding 0.1% sodium hydroxide, 0.2%-0.3% xanthan gum XC, 0.2%-0.3% medium viscosity flocculent Cellulose CMC and 0.1%-0.3% of the above foaming agent. In drilling construction, the above-mentioned recyclable microbubble drilling fluid is firstly prepared, and then the recyclable microbubble drilling fluid is used for drilling. After foaming agent is added to recirculating micro-foam drilling fluid, micro-foam mud is formed, which has good leakage prevention and plugging effect, good lubricating performance and good rheology, which can significantly improve drilling quality and drilling efficiency.

Description

technical field [0001] The invention relates to a drilling technology, in particular to a foaming agent, a circulating micro-bubble drilling fluid and a drilling process using the drilling fluid. Background technique [0002] Due to the influence of its formation conditions, the structure of solid mineral strata is extremely complex. Usually, the development of fractures and broken zones will form lost zones. During the drilling process, drilling fluid will leak from these lost zones, which will affect the normal drilling construction. Especially in large-distance horizontal directional drilling, problems such as drilling fluid loss and slurry emission increase the difficulty of drilling construction. However, in the existing drilling technology, the leakage prevention and plugging effect of the drilling fluid is poor, which reduces the drilling efficiency. Contents of the invention [0003] The object of the present invention is to provide a kind of foaming agent, recyc...
