| titleOfInvention | Drilling stability liquid and drilling method |
| abstract | An object of the present invention is to efficiently and inexpensively provide a drilling stabilizing solution which is hard to rot, has no toxicity, and has excellent drainage. Further, there is provided an excavation method using the excavation stabilizing liquid. A water-soluble polymer (A) having a weight average molecular weight of 1,000,000 or more obtained by polymerizing a monomer composition having an ethyl acrylate ratio of 1 to 20 mol% in all monomer compositions. ) And drilling stabilizer using water as an essential component. It is a preferred embodiment that the insoluble content of the water-soluble polymer (A) is 5% by weight or less. Further, it is an excavation method using an excavation stabilizing solution containing the water-soluble polymer (A). [Selection diagram] None |
