STUDY OF CONDENSATION PROCESS DURING WELL OPERATIONUNDER ABNORMALLY HIGH RESERVOIR TEMPERATURES (BY EXAMPLE OF THE YUBILEINOYE GAS-CONDENSATE FIELD)

Abstract

Some of gas-condensate fields lying at great depths are characterized by abnormally high reservoir temperatures. One of the problems during the operation of wells at depleted fields which are developed without methods to maintain reservoir pressure is fluid accumulation at the bottom. The Yubileinoye gas-condensate field is selected as an example for study. At the field abnormally high reservoir temperature is combined with low molecular weight of formation fluid. Since the change in the content of components produced from the formation to the surface of the gas-condensate mixture changes condensate emission even at the constant volume of gas production. It is important to understand the physical processes occurring in the operation of wells.
