鲁克沁油田开发时,主要选取深层稠油开发注水技术,此项技术应用后油水的粘度相对大,且剖面、平面注采相对严重,对注入水单向突进会产生较大影响。因此,油田开发人员以分层系注水、开发、精细注水以及化学调剖等开发技术为主,不断改善整个平面、剖面矛盾,以使水驱动用的程度得以进一步提升,慢慢恢复地层压力,以保证自然递减得以较好地控制。为此,本文重点基于深层稠油注水开发技术的鲁克沁油田开发做如下分析。
In the development of the Ruqin Oilfield, the main injection technology for deep heavy oil development is selected. After the application of this technology, the viscosity of oil and water is relatively large, and the cross section and plane injection are relatively serious, which will have a significant impact on the one-way sudden water injection. Therefore, oilfield developers are mainly developing technologies such as stratified water injection, development, fine water injection and chemical profile control to continuously improve the contradiction between the entire plane and the section so that the degree of water-driven use can be further enhanced and the formation pressure can be gradually restored. In order to ensure that the natural decline can be better controlled. To this end, this paper focuses on the development of deep heavy oil injection technology in Luqinqin oilfield to do the following analysis.
