酸性气田地面集输工程调查研究

Corrosion Investigation of Surface Gathering Facilities in Acid Gas Field

磨溪气田是典型的酸性气田，投产5年多来，集输工程中出现了一些问题，由四川石油管理局勘察设计研究院组织、四川石油管理局川中油气勘探开发公司参加的磨溪气田地面集输工程调查小组于1996年11～12月在四川磨溪气田进行了实地调查，对投产的14个集气站场及部分单井（250井）的工艺流程及主要设备进行了详细地考察，特别是针对在高矿化度盐水及合H2S、CO2等腐蚀介质条件下所产生的问题，提出了整改措施。

Moxi Gas Field is a typical acid gas field and some troubles occur in gathering facilitiesduring 5 years since its putting into operation. An investigation group consisting of Sichuan PetroleumEngineering Design and Research Institute and Central Sichuan Oil & Gas Exploration and Development Co. under Sichuan Petroleum Administration made on-the -spot investigation for Moxi Gas Fieldincluding process and equipment of 14 gas gathering stations and partial gas wells (25 wells) fromNov. to Dec., 1996, put forward improvenment measures especially for problems occured under highmineralized salt waler, ind H2S & CO2 corrosive medium.
