摘要:
以多元热流体吞吐开发为主要研究对象,结合多元热流体开发稠油时的储层特征,进行多元热流体岩心驱替地层模拟实验、空化水射流破岩实验等,发现多元热流体高温组分的溶蚀作用、气泡的空化作用、降黏作用以及多元热流体的组分变化都会导致储层出砂。进一步通过多组分多元热流体吞吐出砂模拟实验,发现焖井时间是影响出砂的主要因素。针对吞吐开发时的多轮次特点,进行了多轮次出砂模拟实验,随着吞吐轮次的变化,各因素对出砂的影响愈趋明显,即温度影响程度最强,注入速度次之,压力最弱。研究有利于指导精细化防砂,设定合理的生产开采制度,对延长油气井寿命和提升经济效益具有十分重要的作用。
Abstract:
This paper takes the huff and puff development of multi-component thermal fluid as the main research object, based on the reservoir characteristics of multi-component thermal fluid in the development of heavy oil, through searching relevant literature and carrying out formation simulation experiments of multi-component thermal fluid core displacement, cavitation water jet rock breaking and other experiments, it is found that the dissolution of high-temperature components of multi-component thermal fluid, cavitation, viscosity reduction, and composition changes of multi-component thermal fluid will lead to reservoir sand production. Furthermore, through the sand production simulation experiment of multi-component thermal fluid huff and puff, it is found that the soaking time is the main factor affecting sand production. In view of the multi-round characteristics of huff and puff development, multi-round sand production simulation experiments are also carried out in this paper. In view of the multi-round characteristics of huff and puff development, multiple rounds of sand production simulation experiments were carried out. As the huff and puff rounds change, the influence of various factors on sand production becomes more and more obvious, that is, temperature has the strongest influence, and injection speed is the second. In short, the pressure is the weakest. This study is helpful to guide fine sand control, set up a reasonable production and mining system, and play a very important role in prolonging the life of oil and gas wells and improving economic benefits.
