Description
Technical Field
The invention relates to a solid foam drainage agent composition, a preparation method and application thereof, in particular to a solid foam drainage agent composition suitable for an ultra-deep gas well, a preparation method and application thereof.
Background
With the enhancement of the exploitation strength of the gas field, the water output of the gas field becomes a key problem restricting the normal production of the gas well. Foam drainage gas production is a drainage gas production technology which is rapidly developed at home and abroad in recent years, and has the advantages of simple equipment, convenience in construction, low cost, wide applicable well depth range, no influence on normal production of gas wells and the like. Foam drainage is to inject foam drainage agent into a well through an oil pipe or an oil casing ring, and foam with certain stability is generated under the stirring of airflow. The liquid phase slipped and deposited in the pipe is changed into foam, the relative density of fluid at the lower part in the pipe is changed, and the continuously produced gas phase displacement foam flows out of the shaft, so that the accumulated liquid in the shaft is discharged, and the purposes of water drainage and gas production are achieved.
The development of foam drainage agent since the sixties of the last century is carried out abroad, and surfactants such as sulfonate, benzene sulfonate, alkylphenol polyoxyethylene and the like are mostly selected. At present, a multi-component compound system is mostly adopted in the foam drainage agent for drainage and gas production, and in order to enhance the stability of single foam, auxiliaries such as alkali, alcohol, polymer, alkanolamide and the like are usually added into a formula to form reinforced foam. US7122509 reports a high temperature foam drainage agent formulation, which adopts a research idea of neutralization of anionic surfactant and amine to improve the temperature resistance of the system, and the drainage effect and use concentration are not referred to in the patent. US20120279715 reports a foam fluid for increasing oil yield by recovering gas in a gas well, which is an amido group-containing quaternary ammonium salt surfactant having both foam drainage and sterilization functions, a hydrophobic chain is a hydrophobic segment in substituted naphthalene ring, benzene ring or natural oil ester, and has strong chlorine resistance and condensate oil resistance, and also has good corrosion inhibition performance, the foam agent with an active matter concentration of 400ppm has a foam drainage rate of 86.8% in tap water and a foam drainage rate of 79.1% in simulated brine with a mineralization degree of 130000mg/L, however, because an amide group sensitive to high temperature is contained in a molecular structure, the foam fluid has poor adaptability to gas wells with a temperature of more than 100 ℃. China is a technology for researching foam drainage and gas production processes from the last 80 years, and a patent CN102212348A discloses a salt-resistant and methanol-resistant foam drainage agent, which comprises the following components in percentage by weight: 20-40% of cocamidopropyl betaine, 45-65% of amine oxide, 5-20% of alpha-olefin sulfonate, 5-15% of triethanolamine, 0.2-2% of fluorocarbon surfactant and 0-5% of methanol, wherein the mineralization resistance can reach 18 ten thousand, and the amount of the foaming agent is 5000ppm, but the agent contains the fluorocarbon surfactant, so that not only the cost is greatly improved, but also the environmental impact is large.
The results show that the poor high-temperature and high-salt resistance is a main factor for restricting the development of the foam drainage technology of the high-temperature ultra-deep gas well.
Disclosure of Invention
The invention aims to solve the technical problems that the existing foam drainage agent has poor high-temperature resistance in an acid environment, cannot solve the problems of yield reduction and even spray stopping caused by liquid accumulation of a high-temperature ultra-deep gas well and difficulty in filling a liquid foam drainage agent, and provides a solid foam drainage agent composition suitable for the ultra-deep gas well, which is applied to a high-temperature deep well, has very good temperature resistance under an acid condition, and has strong liquid carrying, foaming and foam stabilizing properties.
