目前油井加化学药剂是外围低渗透油田保持油井正常生产的重要手段,但如何加化学药剂及如何用最少药量达到最长的加药周期,提高外围低渗透油田经济效益,是必须解决的问题。本文介绍的套管加药装置,通过矿场试验,在降低采油成本,提高采油效益等方面,取得了较好的效果。1基本结构?
At present, oil well plus chemical agent is an important means to keep oil well normal production in peripheral low permeability oilfield. However, it is an issue that must be solved how to add chemical agent and how to achieve the longest dosing period with the least dose and improve the economic benefit of peripheral low permeability oilfield. . This article describes the cannula dosing device, through the field test, in reducing oil costs, improve oil recovery benefits, and achieved good results. 1 basic structure?
