塔中地区零散试采井放空天然气回收技术应用 李循迹1、王立辉1、侯秉仁2、任东兴1 （1.中国石油塔里木油田分公司，新疆 库尔勒 84100；2.中国石油天然气运输公司沙运司， 新疆 库尔勒 84100） 摘要：油气田开发试采期间,塔中地区有部分零散试采井存在天然气放空现象，国内经济发展迅猛但能源紧缺，回收天放空然气既增加供气能力，又节约能源，减少环境污染。为实现这一目标，现场经摸索实践形成了一套采用撬装化、模块化处理设备，按照2×104Nm3/d、3×104Nm3/d、5×104Nm3/d三个等级进行多撬搭配的天然气回收技术。当实施回收的试采井产气量下降，撬装设备可以重新组合，并在短时间内搬迁至新的井场重复利用。经过近3年的现场应用,设备运行正常已累计回收天然气2.9亿方。该技术的成功应用对今后类似现场放空天然气回收有一定的借鉴作用。 关键词：放空天然气；回收；撬装；技术应用 文献标识码：B The recovery HYPERLINK app:ds:technology%20application \t _self technology application to scattered pilot production wells vent natural gas in Tazhong region Li xunji,Wang li hui,Ren dong xing( Petrochina Tarim Oilfield Company，Korla XinJiang，China 841000) Hou bing ren(CNPC Transporting Company Limited ShaYunSi,Korla XinJiang,China 841000) Abstract：During the trial production period of oil and gas field development process, part of the scattered pilot production wells presence of natural gas venting phenomenon. Recent year domestic economic developing Rapidly, energy shortages, recycling pilot production well venting gas both increase gas supply capacity, also save energy, reduce environmental pollution. For the recovery of this part of the natural gas, a series skid mounted Modular processing equipment were formatted, all skid-mounted equipment were manufactured According to three classes :2×104Nm3/d、3×104Nm3/d、5×104Nm3/d. When the recovery well gas decline, all skid-mounted equipment can be re-combination, and in a short time moved to a new site. After nearly three years of field application, the selected device is running normal cumulative recovery of 0.29 billion cubic meters of natural gas. This technology provide basis for future similar site vent gas recovery.
