【摘要】：我国稠油在油气资源中占有很大的比例,但稠油不同于常规原油,主要是粘度大,很难用常规方法开采,因此需要一些特殊的工艺措施。我国稠油开采已经发展出多种技术如蒸汽吞吐、蒸汽驱、火烧油层等,热力采油就是当今稠油开采主要技术。目前陆地油田的石油产量呈逐年递减趋势,且国家建设和人们生活对石油消费呈逐年递增趋势,所以海上石油产量持续增长是稳定国民石油消费的重要组成部分。渤海油田是国内原油储量和产量比较高的海上油田,稠油储量占其总储量的近2/3左右。由于稠油油藏具有原油黏度高、油层渗流阻力过大和流动性差等特点,水驱开发效果较差,稠油油藏的合理高效开发,对于海上油田的增产稳产具有重要意义。由于海上特殊的自然环境,采油平台空间有限等条件限制,2008年我国在渤海南堡油田开展了B14m井、B2S井注热先导性试验。本文是在现有研究的基础上,以渤海南堡油田南区为研究平台,以B33h和B36h两口热采井为研究对象,从多元热流体吞吐机理,注热参数优化,注热配套工艺设计,现场施工方案及风险分析,热采井产出液处理等方面进行系统研究,提炼出了一套完整的适合海上平台多元热流体吞吐技术工艺设计方法和实施方案,为全面推广海上平台多元热流体吞吐技术,改善海上稠油开发效果,促进海上稠油油田高效开发具有重要指导作用。
[Abstract]:Heavy oil in China accounts for a large proportion of oil and gas resources, but heavy oil is different from conventional crude oil, mainly because of its high viscosity, it is difficult to be exploited by conventional methods, so some special technical measures are needed. A variety of technologies have been developed for heavy oil production in China, such as steam huff and puff, steam drive, burning oil layers and so on. Thermal oil recovery is the main technology of heavy oil production nowadays. At present, the oil production of land oil field is decreasing year by year, and the national construction and people's daily life are increasing year by year, so the continuous increase of offshore oil production is an important part of stabilizing national oil consumption. Bohai Oilfield is an offshore oil field with high crude oil reserves and high production. Heavy oil reserves account for nearly 2 / 3 of its total reserves. Due to the characteristics of high viscosity of crude oil, excessive flow resistance and poor fluidity in heavy oil reservoirs, poor water drive development effect and rational and efficient development of heavy oil reservoirs are of great significance for increasing production and stable production in offshore oil fields. Due to the special natural environment on the sea and the limited space of the oil recovery platform, in 2008, China carried out the heat injection pilot test of B14m well B2S well in Nanbao Oilfield of Bohai Sea. This paper is based on the existing research, taking the south area of Bohai Nanbao Oilfield as the research platform, and taking the two thermal recovery wells B33h and B36h as the research object, from the aspects of the mechanism of multivariate heat fluid huff and puff, the optimization of heat injection parameters and the design of the matching technology of heat injection. Field construction scheme and risk analysis, thermal recovery well production fluid treatment and other aspects are systematically studied, and a set of complete process design method and implementation scheme suitable for offshore multi-element heat fluid huff and puff technology are refined. In order to popularize the multicomponent heat fluid huff and puff technology of offshore platform, improve the development effect of offshore heavy oil, and promote the high efficiency development of offshore heavy oil field, it has an important guiding role.
