摘要
王场油田作为江汉油区最大的整装油田,目前综合含水89.7%,地质储量采出程度41.56%,处于中高含水开发中后期。通过对剩余油分布特征的研究和水驱潜力的评价,认为剩余油呈"普遍存在、局部富集"的特点,并具有较大的提高水驱采收率的潜力。王场油田持续高效开发的技术对策是:坚持滚动勘探开发一体化,按照分类治理的原则,对中高渗透油藏实施精细开发,并通过提液实现深度降压开采;对低渗透油藏分潜431、潜432、潜433共3套层系进行井网重组,并有针对性地制定不同层系的技术措施;同时发展系列配套技术,努力降低能耗。通过多种技术的综合应用,取得较好的稳产效果。
Wangchang Oilfield was the largest un-compartmentalized oilfield in Jianghan Oilfield.Its water cut was 89.7%and geological reserves recovery level was 41.56%,it was at the late stage of production with high water-cut.Based on research of remaining oil distribution and water flooding potential evaluation,it was considered that the distribution characteristics of remaining oil were ' universal existence,local accumulation ',and it had the potential for enhancing the oil recovery further.The technical countermeasures to ensure Wangchang Oilfield keeping stable production and effective development are to insist on the integration of exploration and development,and treat and control according to the principle of classification,carry on fine development on high-permeability reservoirs,implement production by lowing pressure in deep zones,for low-permeability reservoirs,such as Eq4 3 1,Eq4 3 2 and Eq4 3 3 well patterns were reconstructed,countermeasures were set up for different zones.At the same time,matching technologies were developed to reduce the energy consumption.By means of integrated application of many technologies,stable oil production is realized to guide production.
