川西气田采出水处理现状及技术对策研究

Research on Water Treatment Status and Technological Countermeasures in West Sichuan Gas Field

川西气田气水同产现象十分普遍,产出的采出水具有高COD含量的特点,处理达标外排十分困难。针对目前川西气田采出水处理现状,本文通过对川西气田采出水进行水质分析,明确了采出水COD值偏高主要是由于泡排剂等药剂的大量加入和凝析油的乳化,提出源头分类、达标排放及回收再利用等技术对策来协同处理采出水,为西南油气田缓解采出水环保压力提供了方法和思路。

The gas and water production in west sichuan gas field is very common, and the output is characterized by high COD content, it is very difficult to deal with the external drainage. For the current situation of water treatment in west Sichuan, in this paper, the water quality analysis of west Sichuan gas field was analyzed. It is clear that the COD value of the extraction of water is mainly due to the large amount of adding and condensate emulsification. To put forward technical countemaeasures such as source classification, standard emission and recycling, etc, to deal with the extraction of water, it provides methods and ideas for alleviating environmental pressure in southwest oil and gas fields.
