低渗透气田加密调整技术研究

Research into Infill Drilling Adjustment Technology of Low-Permeability Gasfield

加密调整是保持气田稳产的重要技术措施。为了提高低渗透气田的采收率和开发经济效益．基于气藏工程理论，采用动态法计算气井动态储量、储量动静比、泄流范围等有关开发技术指标，结合气井静、动态特征进行分类．分析、评价不同类型气井开发效果，从而指出需要进行加密调整的井区，加密部署井距参考邻井泄流直径、物性等。提出的气田加密调整技术方法思路新颖、实用有效、简便易行。

Infill drilling adjustment is important to maintain the stable gas field technical measures. In order to improve oil recovery in low permeability gas, field development and economic benefits, based on the gas reservoir engineering theory, using dynamic method calculate well dynamic reserves, static and dynamic ratio of reserves, the discharge range etc. technological development indicators, combining with gas wells static and dynamic characteristics, classifying, analyzing, evaluating the different types of gas wells development effect, thus the need to be infilled adjusting well. Discharge diameter of adjacent wells can be reference for well spacing of infill drilling deployment, properties and so on.
