Abstract

The integrity of high temperature and high pressure (HTHP) gas well is one of the challenges to the safe and stable production of Tarim Oilfield. As a result, conducting test and evaluation on these wells are of great significance. In this paper, the state of the art of researches related to annular pressure are firstly reviewed, which is followed by the summary of the characteristics and applicable scenarios of the well integrity techniques. In terms of the fact that there are a lot of HTHP gas wells with annular pressure but large scale logging or snubbing operation is unworkable, a method of preliminary integrity is developed. For this method, annular pressure relief and recovery are firstly carried out, with using the ultrasonic method to determine the liquid level of annular space, the pressure gradient and leakage of the annular space can be determined. By using this method, test and evaluation on annular pressure of a HTHP gas well in Tarim Oilfield are conducted and the failure of well barrier parts are determined. Study and filed test show that this simple method can be useful in the preliminary screening of HTHP gas wells before the large scale test operation and thus providing technical support for the logging and snubbing operations.
