【摘要】：枯竭油气藏型储气库建库时筛选满足重复利用条件的老井用于注采气能够有效减少新钻井数量、降低建库成本。由于该方面可供借鉴的公开资料十分有限,在此以23储气库为例,根据气库设计要求,结合专家咨询和资料调研成果,采用AHP层次分析法对拟利用井初步筛选指标进行对比分析,最终优选出固井质量、井筒状况、气井服役年限及井身结构4类关键性指筛选标,在此基础上建立了拟利用老井筛选原则。依据该原则从文23气田主块57口老井中筛选出11口可利用井,先导注气试验结果表明筛选出的老井能够圆满完成现场注气任务,进一步印证了该筛选原则的适用性和可靠性。
[Abstract]:The selection of old wells satisfying the conditions of reuse for gas injection and production can effectively reduce the number of new drilling wells and reduce the cost of building reservoirs. Due to the very limited public information available for reference in this respect, taking 23 gas storage tanks as an example, according to the requirements of gas reservoir design, combined with expert consultation and data research results, This paper uses AHP analytic hierarchy process (AHP) to compare and analyze the preliminary screening indexes of wells to be used. Finally, four kinds of key index screening criteria, such as cementing quality, wellbore condition, service life of gas wells and wellbore structure, are selected. On this basis, the principle of selecting old wells is established. According to this principle, 11 available wells were selected from 57 old wells in main block of Wen23 gas field. The pilot gas injection test results show that the selected old wells can successfully complete the field gas injection task, which further confirms the applicability and reliability of the screening principle.
