高凝油开采成本居高不下的主要原因是原油含蜡高,在开采中需要应用热线和电热管技术采油,经过近几年对沈84-安12块的研究和实践,针对高凝油井中、高含水期开采,通过化学冷采技术及提高单井液量等措施,可实现高凝油中高含水期的冷采,大幅度地降低了高凝油的开采成本,在降低高凝油开采成本上取得技术进展。 The main reason for the high cost of high pour point extraction is the high wax content of crude oil. In the exploitation, it is necessary to apply hot line and electric tube technology to recover oil. After researching and practicing Shen 84-An 12 in recent years, , High-water-cut mining, cold-mining with high water cut in high pour-off oil can be achieved through measures such as chemical cold-extraction technology and single-well liquid volume increase, drastically reducing the production cost of high pour-off oil, The cost of making technological progress.
