Prediction method for condensate gas well yield

Abstract

According to the method for predicting the yield of the condensate gas well, the yield prediction standard curve of the condensate gas well is established, the abscissa of the yield prediction standard curve is the yield of the condensate gas well, and the ordinate of the yield prediction standard curve is the kilometer heat loss of a wellbore. The mathematical function relation between the yieldof the condensate gas well and the kilometer heat loss of the wellbore is obtained, the kilometer heat loss of the wellbore on the date to be measured is obtained, the numerical value is input into the function corresponding to the yield prediction standard curve, and the yield of the condensate gas well on the date to be measured can be uniquely determined according to the function relation. Theyield of the condensate gas well can be continuously obtained without well staying of a well staying technology, and then the production system of the condensate gas well is adjusted in time accordingto the yield of the condensate gas well.

Description

technical field [0001] The invention relates to oil extraction technology, in particular to a method for predicting the output of condensate gas wells. Background technique [0002] For condensate gas reservoirs exploited by depletion, the daily production control is too small, condensate oil is trapped in the seepage channel of the formation, a large amount of oil in the formation is lost, the daily production control is too large, the production energy is depleted rapidly, and reverse condensation occurs at the bottom of the well analysis, affecting the recovery of condensate oil. Reasonably determining and adjusting the output of condensate gas fields and reducing the loss of formation condensate oil are the key issues to improve the economic benefits of condensate gas fields. [0003] In the existing technology, the production data of condensate gas fields are mainly obtained through metering separators. Metering separators are installed on test production single wells ...
