摘要:
渤海中深层储层普遍具有中低渗透率、高温的油藏特点,注水开发过程中存在注入压力较高、纵向吸水剖面严重不均、部分注采井间水窜明显以及传统凝胶类、颗粒类调剖体系适应性差等问题。为了改善水驱开发效果,在渤海中深层油藏K油田开展了层内生气调剖技术应用试验。对已实施井组开展调剖效果评价及其影响因素分析,结果显示,层内生CO2和层内生N2调剖体系均对中深层油藏的渗透率、温度有很好的适应性,也取得较好的解堵降压与降水增油效果,分析认为体系生气反应速度、注入方式及应用轮次等对调剖效果影响较大,并指出下步改善方向,为类似油田调剖技术的开展提供指导和借鉴。
Abstract:
The middle and deep reservoirs in Bohai Sea are generally characterized by low and medium permeability and high temperature. In the process of water injection development,there are some problems,such as high injection pressure,serious uneven longitudinal suction profile,obvious water channeling between some injection-production wells,and poor adaptability of traditional gel-type and granular profile control systems. In order to improve the effect of water drive development,the application test of in-layer gas generation control technology was carried out in the K Oilfield of Bohai Sea. The profile control effect evaluation and influencing factors analysis were carried out for the implemented well groups. The results showed that the endogenous CO2 and N2 profile control system had good adaptability to the permeability and temperature of the medium and deep reservoir,and also achieved good effects of plugging relief and pressure reduction and precipitation oil increase. It was analyzed that the gas reaction rate,injection mode and application rounds of the system had a great influence on the profile control effect. The next improvement direction is pointed out to provide guidance and reference for the development of similar oilfield profile control technology.
