| titleOfInvention | a drilling fluid |
| abstract | A drilling fluid comprises 100 parts by weight of slurry preparation water, 0 to 0.6 parts by weight of a pH regulator, 0.8 to 3.0 parts by weight of a bag of multifunctional materials, and 0 to 100 parts by weight of a weighting agent. The characteristics of this drilling fluid are: simple preparation, ready-made system with one or two agents, very easy to apply and adjust on site; The eye is clean and stable; it is also economical and environmentally friendly, non-toxic and biodegradable, easy to handle, and low overall cost. It can meet the current environmental protection, low-cost and fast drilling needs, and has a very wide application prospect. |
