Problems solved by technology

However, the sources of foam drainage agents currently used are complex and the dosage varies, which makes the post-emulsification treatment of the emulsion more complicated.
The existing oil-soluble condensate oil demulsifier products are difficult to meet the requirements of low dosage, fast demulsification speed, and high condensate oil recovery rate, or poor compatibility, and it is difficult to fully meet the needs of on-site production

Abstract

The invention discloses an oil-soluble condensate oil demulsifier, which is prepared through reacting an SP-type demulsifier, an AP-type demulsifier, an AE-type demulsifier, an AR-type demulsifier and an organic acid and adjusting the pH to be 7-10. The demulsifier has the characteristics of good compatibility, small dosage, high demulsifying speed, high condensate oil recovery rate and clear oil-water interface after demulsifying. Effective separation of oil and water can be quickly achieved through condensate oil after demulsifying at a room temperature, efficient recovery of the condensate oil is ensured and the water treatment technology is simplified. The invention further provides a preparation method of the oil-soluble condensate oil demulsifier. The method is simple in step and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of three-phase separation of oil, gas and water in the field of gas field exploitation, in particular to an oil-soluble condensate oil demulsifier and a preparation method thereof. Background technique [0002] Condensate refers to the liquid phase components condensed from natural gas in condensate gas fields. The main component is a mixture of C5-C8 hydrocarbons. It is divided into three types: paraffin base, intermediate base and cycloalkyl. It occupies a place in the world's oil field development. Domestic condensate oil production areas are mainly distributed in Xinjiang Oilfield, Zhongyuan Oilfield, Donghai Oilfield, and Sichuan Oilfield. Most of these reservoirs have the characteristics of light oil quality, high gasoline content, and significant economic benefits. [0003] Foam drainage and gas recovery technology is one of the main methods of drainage and gas recovery. It injects foam drainage a...
