Research On The Downhole Dynamic Test Technique Of The Steam Injection Well

In the world, the storability of heavy crude oil resource is so rich that it exceeds conventional crude oil. As the price of global oil is increasing and the probability of finding out huge clean oil reservoirs is decreasing, the development of heavy crude oil resource obtains more and more respect. An important field of research on the development of oil and gas is completing petroleum reservoir performance and conducting optimization of production, and among them, management of oil reserve pressure and temperature is the basis of conducting effective management and enhancing oil recovery in oil reservoirs. It is very important for conducting optimization of production and enhancing oil recovery to research a technique which is able to monitor manifold parameters of oil reservoir continuously and in real time. The downhole dynamic checkout technique of the steam injection well is proposed on the basis of actual situation of field production. The technology is able to not only achieve downhole temperature and pressure dynamic test in both injection well and production well in real time, and also proceed drawdown test in soak stage of injection well.The Successful application on location indicates that, this technology has ont only resolved the technologic problem of steaming monitoring of heavy oil recovery in real time inland and outland, and also broken the situation in which the way of heavy oil recovery test is only memory type mode at home, and it offers effective technologic method for shengli oil field to recovery both heavy oil reservoirs and extra-heavy oil reservoirs with techniques such as steam drive and SAGD and so on.
