Abstract

The invention discloses an environmental-friendly type foam water-draining agent and a preparation method thereof. The environmental-friendly type foam water-draining agent adopts a biodegradable material; and the foam water drainage refers to discharging liquid accumulated at the bottom of a well out of the well by utilizing the water containing performance of foam and the own capability of the well bottom so as to realize the purpose of increasing the yield of the natural gas well. In a field experiment, the foam water-draining agent disclosed by the invention has the advantages that the foam water drainage gas producing process can be met by good foaming capability, foam stabilizing capability and liquid carrying capability, and the foam water-draining effect can be achieved. The environmental-friendly type foam water-draining agent is characterized by comprising the following components of: cocamidopropyl dimethylamine hydroxysultaine, dodecyl dimethyl betaine, alkyl glycoside, cocamidopropyl betaine, lauramidopropyl betaine, dodecyl dimethyl ammonium oxide, hexadecyl trimethyl ammonium chloride, fatty alcohol polyoxyethylene ether, urea and water.

Description

technical field [0001] The present invention relates to foam drainage and gas recovery technology for natural gas wells, in particular to an environment-friendly foam drainage agent and its preparation method. The environment-friendly foam drainage agent uses biodegradable raw materials. The foam drainage It refers to the use of the water content of the foam and the energy of the bottom of the well to discharge the well fluid to the outside of the well to achieve the purpose of increasing the production of natural gas wells. The foam drainage agent can satisfy the foam drainage and gas recovery process with its good foaming ability, foam stabilizing ability and liquid-carrying ability in the field experiment and achieve a remarkable effect of drainage and gas recovery. Background technique [0002] With the continuous development of gas fields, the capacity of gas reservoirs and the pressure of gas wells continue to decrease, natural gas wells have successively produced form...
