Development Techniques for Abnormal High-Pressure Gas Fields and Condensate Gas Fields in Tarim Basin

摘要

Tarim Basin is the most hydrocarbon-abundant onshore basinrnin China. It occupies an important position in “West-to-EastrnGas Transportation” project. The major force gas fields are ofrnlarge scale, abnormal high prossure and high productivity of arnsingle well. The condensate gas fields are usually of highrnformation pressure, high condensate oil content and highrnpressure of dew point. Through deepening study on therndevelopment mechanism and development technologies of therngas fields and condensate gas fields, a series of developmentrntechnologies in the super-deep and high-pressure gas fieldsrnand condensate gas fields in Tarim Basin have come intornbeing in the development practice. The technologies not onlyrnhave helped to build up Yaha Condensate Gas Field with thernlargest condensate oil productivity in China, but also havernbeen extensively applied in the early-stage developmentrneveluation of several gas fields in “West-to-East GasrnTransportation” project and the comprehensive adjustment ofrnKekeya Condensate Gas Field. A new model has been createdrnto develop super-deep and high-pressure gas fields andrncondensate gas fields.
