【摘要】：我国当下的石油开采技术,虽然相比国外有一定的差距,但是方法多种多样,其中一种比较重要的开采方式是注水开采。我国石油开采方式大都是依靠地层压力进行开采,而注水克服了地层压力不足的缺点,并且在实际开采过程中,注水可以开采依靠地层能量无法开采的石油,提高了采收率。但是就注水而言,本身就是一项宏大的工程,随着这些年我国注水技术的大面积推广,我国利用注水来开采石油的项目也越来越多。我国注水的发展具有一定的历史,对于不同阶段的石油开发,以及对注水要求的不同,我国注水按照不同因素可以分为多种,这主要是因为注水的规模与性质不同。就目前我国的注水而言,主要有两种早日注水与二次注水两种。早日注水是为了稳固地层的压力,在日后的开采时,可以顺利并稳定地进行开采,以便有效进行后续开采。在这个过程中,可以保持泵到干流的阻力、地面与注水管道的阻力、油藏压力都由其提供。二次注水通常是在开采时压力不足时,为提供一定的能量而采用方式。在实际注水中,这两种注水方式的表现非常接近,而且都与地层等性质相关。在进行注水时,整个注水过程都是由注水站负责,注水站在过程中控制着整个注水工作。在对实际的注水效率进行审核之后,发现在整个过程中,有需要可以改善的地方。在实际注水中,为了高效的对注水进行控制,提高注水的效率,并且帮助注水站改进注水流程,并且减少人为成本,减少安全事故的发生。本文的出发点是整个注水环节的管理工作,可以高效科学的对所有的注水工作进行管理,来研发了注水站24小时管理系统,可以对井场上相关设备进行管理与控制,在此基础上来研究泵工作时最适合的压力,以及减少注水工作的费用成本,设计最佳的注水方案。在上述研究的基础上,建立一定的模型,然后使用计算机软件,通过在现场进行综合实验,来设计注水进水检测系统,然后绘制注水曲线。在试验后。取得的实验成果符合理想状况,提高了注水效率,控制了注水成本,具有一定的价值与意义。对于油气开采而言,注水是一项实际生产中比较常见的开采措施,特别是对于我国陆地上开采的石油,但是在实际注水中发现注水耗费的成本非常多。随着目前我国开采含水率较高的油田的数量越来越少,注水的成本在不断上升。对于油田开发而言,控制其发展成本对于改善油田的成本非常重要。本文研究的出发点是南十五注水站,通过对注水系统进行改良,找出注水最大的能源消耗,并找到解决方法。
[Abstract]:Although there is a certain gap between China and foreign countries, there are a variety of methods, one of which is water injection. Most of the oil exploitation methods in China depend on formation pressure, but water injection overcomes the shortcoming of insufficient formation pressure, and in the process of actual exploitation, water injection can exploit the oil which can not be exploited by formation energy, which improves the recovery efficiency. However, as far as water injection is concerned, it is a great project in itself. With the popularization of water injection technology in China in recent years, there are more and more projects using water injection to exploit oil in our country. The development of water injection in China has a certain history. For different stages of oil development and different requirements for water injection, water injection in China can be divided into a variety of factors according to different factors, which is mainly due to the different scale and nature of water injection. At present, there are two kinds of water injection in China: early water injection and secondary water injection. Early water injection is to stabilize the formation pressure and can be exploited smoothly and stably in the future in order to effectively carry out subsequent mining. In this process, the pump to the main flow resistance, surface and water pipeline resistance, reservoir pressure are provided by it. Secondary water injection is usually used to provide certain energy when the pressure is insufficient. In the actual water injection, the performance of these two water injection methods is very close, and both are related to formation and other properties. In the process of water injection, the whole water injection process is controlled by the water injection station. After reviewing the actual water injection efficiency, it is found that there is room for improvement in the whole process. In order to control the water injection, improve the efficiency of water injection, and help the water injection station to improve the water injection process, and reduce the artificial cost, reduce the occurrence of safety accidents. The starting point of this paper is the management of the whole water injection link, which can efficiently and scientifically manage all the water injection work, and develop the 24 hour water injection station management system, which can manage and control the equipment related to the well field. On the basis of this, the most suitable pressure is studied, and the cost of water injection is reduced, and the best water injection scheme is designed. On the basis of the above research, a certain model is established, and then the water injection detection system is designed and the water injection curve is drawn by using the computer software and the comprehensive experiment in the field. After the experiment. The experimental results accord with the ideal condition, improve the water injection efficiency and control the water injection cost, which has certain value and significance. For oil and gas production, water injection is a common measure in actual production, especially for the oil produced on land in China, but the cost of water injection is very high. With fewer and fewer oil fields with high water cut, the cost of water injection is rising. For oilfield development, it is very important to control the development cost to improve the oil field cost. The starting point of this paper is to improve the water injection system to find out the largest energy consumption of water injection and to find out the solution.
