【摘要】 我国不少注水开发油田都已进入特高含水阶段,水油比急剧增大,经济效益显著变差,因而迫切需要研究油井经济极限含水界限问题。文中提出了油井经济极限含水率的概念,超过这个界限,油井生产即没有经济效益。通过对几个油田的实际调查研究,得出油井经济极限含水率的计算方法和实例计算结果,并提出了对特高-超高含水井进行治理的措施建议,从而改善了油田的开发效果,提高了经济效益。

【Abstract】 There are many waterflooding oilfields in China, which have got into high water content stage. Their water-oil ratio increases rapidly, and the economic benefit is marked bad. The paper puts forward the concept of economical limiting water content about oil well. If the water-oil ratio overtakes the limiting water content,the oil well’s production hasn’ t economic benefit. According to the actual investigation of several oil fields, we get the calculation method of economical limiting water content of oil well and the calculation result of case history, and put forward the suggest how to run the high and superhigh water content well.
