Embodiment 1
[0011] The rare earth gain agent includes the following materials, by weight: cyclopentadiene rare earth 1.5-25%, cyclopentadiene manganese carbonyl 1.5-5%, ferrocene 2-6%, absolute ethanol 10-40%, methanol 5-30%, petroleum ether 5-20%, xylene 5-18%, dimethyl ether 10-30%, mix the above substances at room temperature according to the above ratio, stir evenly, and get a clear and transparent brown or brownish yellow solution , that is, the rare earth gain agent is obtained, and it is used for future use.
[0012] The prepared rare earth gain agent is put into the 35-liter steel container first, and the addition amount of the rare earth gain agent accounts for 0.3-1.2% of the total weight, and then natural gas is filled into the steel container, and it can be used after standing for 0.5 hours.
Embodiment 2
[0014] 1) Prepare 1 kg of rare earth gain agent: weigh 100 grams of cyclopentadiene rare earth, 20 grams of cyclopentadiene manganese carbonyl, 40 grams of ferrocene, 300 grams of absolute ethanol, 220 grams of methanol, 100 grams of petroleum ether, 150 grams of toluene, 70 grams of dimethyl ether, cyclopentadiene rare earth is cyclopentadiene containing 23-27% lanthanum, 49-52% cerium, 3.5-6% praseodymium, 14-16% neodymium and a small amount of medium and heavy rare earth cyclopentadiene ene compound, mix the above substances at room temperature, stir evenly, and obtain a clear and transparent brown or brownish-yellow solution, that is, a rare earth gain agent, and set aside.
[0015] 2) Add 0.045 kg of the prepared rare earth enrichment agent into a 35-liter steel container, then fill the steel container with 3.8 kg of natural gas, and let it stand for 0.5 hours before use.
[0016] Adopt the natural gas prepared by embodiment 2, the steel plate cutting contrast experiment ...
Embodiment 3
[0020] 1) Prepare 1 kg of rare earth gain agent: weigh 100 grams of cyclopentadiene cerium, 20 grams of cyclopentadiene manganese carbonyl, 30 grams of ferrocene, 300 grams of absolute ethanol, 220 grams of methanol, 100 grams of petroleum ether, 170 grams of toluene and 60 grams of dimethyl ether were mixed at room temperature and stirred evenly to obtain a clear and transparent brown or brownish-yellow solution, that is, a rare earth gain agent, which was set aside.
[0021] 2) Add 0.045 kg of the prepared rare earth enrichment agent into a 35-liter steel container, then fill the steel container with 3.8 kg of natural gas, and let it stand for 0.5 hours before use.
[0022] Adding rare earth booster to the coalbed methane in Jincheng, Shanxi, preheating and drilling a 40mm steel plate, the time is 9 seconds, and the punching time is 13 seconds. This is the test data of the coalbed methane in Jincheng, Shanxi.
[0023] Rare earth additives were added to coalbed methane in Jin...
