摘要/Abstract

摘要： 针对苏里格气田低渗透气藏有节流器气井井筒内临界携液参数取值认识不清的问题,建立了有节流器气井气液两相流动压力分布模型,分析了4种临界携液模型的适用性,总结了该区块有节流器气井的临界携液参数沿井深的分布规律。研究表明:Turner、Coleman、Peng Zhaomin模型适合判定苏里格气田气井是否积液;有节流器气井临界携液流速随井深增加而持续减小,在节流器位置突降,井底处最小;临界携液流量在节流器上方随井深增加持续降低,在节流器下方持续增高,其最大值位于井口;建议以临界携液流量沿井深分布的积分与井深的比值做为临界携液流量的最终值。该研究对提高临界携液模型应用效果及气井稳产具有重要指导意义。

Abstract: In the low-permeability reservoirs of Sulige Gas Field, aiming at the problem of unclear understanding of critical liquid-carrying parameters in the wellbore of gas wells with restrictor, a pressure distribution model for gas-liquid two-phase flow in gas wells with restrictor was established, and the applicability of four types of critical liquid-carrying models were analyzed. The distribution law of critical liquid-carrying parameters along the depth of gas wells with restrictor was summarized. The research show that: Turner, Coleman, and Peng Zhaomin models are suitable for judging whether the gas wells in Sulige Gas Field have fluid accumulation; the critical fluid-carrying rate of gas wells with restrictor continues to decrease with the increase of well depth, with a sudden drop around the position of the restrictor and a minimum value around the bottom of gas wells; above the restrictor, the critical fluid-carrying volume continues to decrease with the increase of well depth, while below the restrictor, the critical fluid-carrying volume keeps increasing, and the maximum value appears around the wellhead. It is recommended to take the quotient of the integral and the well depth as the final value of critical liquid-carrying volume, where the integral is from the distribution of critical liquid-carrying volume along well depth. This research has a guiding significance for improving the application effect of the critical liquid-carrying model and for stabilizing production of gas wells.

Key words: critical liquid-carrying parameter, low-permeability gas reservoir, turner model, restrictor, Sulige Gas Field
