Abstract

The invention provides a foam scrubbing agent and a preparation method thereof. The foam scrubbing agent is used for solving the problem that a foam scrubbing agent in the prior art cannot meet high temperature resistance, salt resistance and gas condensate resistance at the same time. The foam scrubbing agent is prepared from the following components in percentage by weight: 15-25% of coconut oil acyl propyl hydroxyl sulfobetaine, 5-10% of dodecyl imidazoline, 3-15% of alkyl polyether ammonium oxide, 1-3% of an organic solution, 0.5-1% of an inorganic salt solution and the balance of water. Through functions and synergistic effects of all the components in the formula, selection of raw materials, and optimal formula tests, the fluid carrying capacity of the foam scrubbing agent is still high when the mineralization degree is high. The foam scrubbing agent provided by the invention has the advantages that the foam scrubbing agent has good liquid-carrying capacity in the presence of high-content (30%) gas condensate, the components have good synergistic effect, good foam scrubbing effect and good compatibility with other chemical assistants, and the preparation method of the foam scrubbing agent is low in cost, simple, low in production cost and easy to realize batch production.

Description

Technical field [0001] The present invention belongs to the chemical aids and synthesis, and more particularly to a foxtile and a preparation method thereof. Background technique [0002] With the in-depth of gas field development, the gas well production, the pressure gradually decreases, which causes the water gas well to cause a difference in self-carrying capacity, the fluid fluid is severe, the reservoir energy is less than, the gas cannot bring the well water to the ground, water It gradually accumulates in the wellbore, which seriously affects the yield of the gas well, so it is necessary to drain and gas. [0003] The foam drainage gas is a drainage gas technology that has developed rapidly in recent years. Its essence belongs to chemical drainage, which is the bubble property of surfactants in chemical agents, and the chemical active agent and well bottom by mixing the surfactant in chemical agents. The fluid acts generates a foam, reducing the density of the flow medium...
