苏里格东部气田气井合理配产技术

苏里格东部气田规模开发对单井稳产提出了要求,而该区块特殊的地质特征和低成本开发思路限制了常规配产方法的使用,迫切需要一种简单实用的气田开发方法指导合理配产。对已投入开发气井合理产量方法进行总结评价,对目前简化试气中存在的问题进行了深入分析,指出常规"单点法"无阻流量用于指导配产存在一定的局限性;在充分分析试采井动静态资料的基础上,提出通过摸索已投产井稳定产量与无阻流量的关系,总结两者匹配关系、规律,可指导新井配产。

Reasonable production proration technique of eastern sulige gasfield

The large exploitation of eastern part of sulige gas field requires stable single well production.But the special geological features and low cost of development limits the capacity of conventional production proration methods.A simple and practical methods of gas field development to guide the development of the field with reasonable production is urgently required.After evaluation of methods of gas wells that have been put into production and deep analysis of problems existed in simplified gas test,we found that there are some limitations in the conventional"single-point method"used to guide the allocation of free flow of production.On the basis of full analysis of static and dynamic well test datas,a method to guide allocation by groping the relationship between stable production and open flow and Summing up the relationship between the two matching was proposed.
