摘要：

As in the Ying-Qiong basin, in a number of target layer formation of wells, the pressure is over 100MPa, and downhole temperature exceeds 170 degrees C. It has great challenges and risks to the well test operation. Therefore, risk assessment and technology research for high-temperature super-pressure testing are needed. In this article, HPHT well test safety control technology is studied from the aspects of wellbore temperature and pressure field and hydrate prediction, and the theoretical calculation module of wellbore temperature and pressure field during HPHT test is established. Based on simulated experiment, the prediction module of gas hydrate formation conditions is established. Combined with field conditions of HPHT test, it proposes specific measures to control hydrate to further reduce the risks of testing operation.
