Used for oil extraction (hydrops) drainage technology of the well. This process is known as the oil (gas) induced spray (drainage) technology. Foaming agent with pump truck or proportion of plunger pump from tree lubricators directly into the oil and gas Wells.
Recommended dose = 0.1% of the bottom hole water + 0.1% of the daily fluid or according to the estimation of nissan water meter, 0.5 ~ 10 kg/m3. To timely adjust the dosage according to the using effect and well conditions.
Selecting well conditions: a. caused by bottom water production, production of oil and gas Wells; B. gas-liquid ratio in more than 350 Wells.
Used for foam sand washing process. Foaming agent mixture will W - 101 1 ~ 6% aqueous solution, using pressure fan and pump truck according to certain proportion to gas and aqueous solution foaming agent into the foam generator, the foam generator to produce foam fluid into the wellbore sand washing. The sand washing process should be determined based on the depth of the formation pressure and wellbore gas liquid ratio. To wellbore pressure control in general, equal or slightly bigger than the formation pressure is less than the static water pressure, so can reduce the leakage, and guarantee the spit no sand reservoir. If reservoir, high temperature and in order to control the wellbore pressure to less than the formation pressure. Recommended dose: according to the leakage of oil Wells, general is 80 ~ 600 kg.
Product packing can be made according to request of users, in general, there are 50 kg and 200 kg of two kinds of packaging. Transportation should avoid packing damage to avoid leakage.
Product should be stored and ventilation, cool and dry place. In the guarantee of the provisions of this standard under the condition of storage, transportation, one year warranty.
