Dina-2 Condensate Oil And Gas Field Pipelines Operating Mode Simulation Study

Due to the rapid development of the target marketing economy in the project of "Gas rranfmission from West to East" and the severe shortage of energy sources,the current supply of energy sources is far from meeting the requirement,thus the exploration of new oil and gas fields is in urgent need.Dina 2 gas field is an undeveloped gas condensate field,with 1503.45×10~8m~3 natural gas reserve and 1181.02×10~4t gas condensate in place,and the exploration of which is of fundamental importance to ease the shortage of energy sources in the target market.As Dina 2 gas field locates in the desert,the application of two-phase flow cannot only economize project investment and operating cost,but also enables oil and gas fields in abominable surroundings to get rapid development.This paper brings forward rationale design scheme through the research of pipe pressure drop,holdup,flow model and temperature change.Since Dina 2 gas condensate field has not been put into production and the calculating model is not mature yet,the production parameter is unpredictable through software,Therefore,tazhong6 gas and oil condensate field which has already been put into production is found as an analogy by parameter comparison.Through check calculating of tazhong6 gas and oil condensate field by HYSYS software under different working conditions and the comparison of computer model combinations,a group of calculating model are got with minimal error.The design scheme of Dina 2 oil and gas condense field is basically established through the prediction of four key parameters as pipe diameter,holdup,hydrate,pressure,and the programming of two-phase flow temperature drop calculating procedure by VB.
