The invention discloses an anti-collapse and anti-leakage drilling washing fluid used during drilling and a field production method thereof, belongs to the technical field of geological core drilling technology, and aims to solve the problem that drilling washing fluid is poor in wall protecting effect under the stratum conditions of strong breaking and continuous leakage. The drilling washing fluid is characterized in that 30-50kg of bentonite, 2-4kg of soda ash, 2-5kg of tackifier, 20-50kg of fluid loss agent, 5-15kg of flow pattern regulator, 30-80kg of bridging agent, 20-50kg of blocking agent, 10-30kg of inhibitor and 1-3L of foaming agent are added to each cubic meter of water. The anti-collapse and anti-leakage drilling washing fluid has the advantages that the drilling washing fluid is good in collapse preventing effect, fast in leakage blocking, high in leakage blocking strength, wide in adaptive crack width range, and widely applicable to the drilling of water-sensitive and loose and broken stratums, low-pressure leakage layers and fracture hole developed stratums.

The invention provides a rich-foam toilet cleaning block which comprises an anionic surfactant, a nonionic surfactant, tea saponin, sodium alginate, sodium citrate, a bactericidal deodorant, sodium chloride and the like. The bactericidal deodorant used in the rich-foam toilet cleaning block is one or mixture of more of broadleaf holly leaf extract, cloven extract, phellodendron bark extract and mint extract. The rich-foam toilet cleaning block has excellent foaming and foam stabilizing capacities, and can effectively remove yellow scales, urine scales and water scales. By adopting the pure plant extracts, the rich-foam toilet cleaning block can efficiently decompose peculiar smell, has the bactericidal and deodorizing functions, and is harmless to the human body and environment. The rich-foam toilet cleaning block can emit a natural fresh plant odor on the premise of deodorization.

The invention discloses a foaming agent for a low temperature-resistant soil pressure balance shield, and a preparation method and the application of the foaming agent. The foaming agent is prepared from formulation components in percent by weight: 2 to 4 percent of alpha-olefin sulfonate, 4 to 10 percent of fatty alcohol-polyoxyethylene ether alkyl sulfate, 1 to 2 percent of coco fatty acid diethanol amide, 0.5 to 1 percent of cocamidopropyl betaine, 0.5 to 2 percent of polyethylene glycol, 0.1 to 0.5 percent of glycerol, 0.05 to 0.3 percent of lauryl alcohol, 0.1 to 0.5 percent of sodium chloride, 0.05 to 0.15 percent of 5-chloro-2-methyl-4-isothiazolin-3-one, 0.05 to 0.2 percent of citric acid and the balance of 79.35 to 91.65 percent of water. The foaming agent disclosed by the invention is used for construction under minus 20 DEG C, is particularly suitable for winter construction and is used for improving a soil body of which a construction soil layer is fine sand, medium-coarse sand and / or sandy gravel, the transparency of the foaming agent used for shield construction under a low-temperature condition in winter is ensured, so that a high foaming rate of the foaming agent is ensured, the foam stability is high, and an adverse effect brought to the construction as the foaming agent changes along with the temperature is reduced.

The invention discloses a negative-nonionic sulfonate high-temperature foamer for oil extraction. The invention adopts the technical scheme as follows: the foamer is characterized by belonging to negative-nonionic surfactants and mainly comprises the following components: a Spann sulfonate surfactant, a Tween sulfonate surfactant, a foam stabilizer and a pH regulator. The foamer has the benefits that negative-nonionic sulfonate is adopted as a main raw material; the foamer is applied to a site, is good in water solubility and dispersity when being used in an oil-water well, is good in foamability and excellent in foam stability at high temperature (89 DEG C), and belongs to new-generation high-temperature foamers; foam generated by the foamer is very high in surface strength and very stable; the foamer is good in compatibility with wastewater; the gas release speed is high and can be controlled; the effect of foaming for foam flooding is achieved.

The invention relates to a self-stabilized carbon dioxide / ammonia water switch foam system which is composed of CO2, a bubbling liquid and ammonia water. The CO2 is stimulating factors and bubbling gas, the ammonia water is a defoaming liquid, the bubbling liquid is prepared from a bubbling agent and deionized water, the bubbling agent accounts for 0.1-1% by mass of the bubbling liquid, and the bubbling agent is erucyl amide propyl-N,N-dimethyl tertiary amine or oleic amide propyl-N,N-dimethyl tertiary amine. The foam system is simple in component and sensitive in foam switching property, and still has relatively good foaming property and switching property in a high-temperature and high-pressure environment.
