苏里格气田致密砂岩气藏的天然气储量规模和年产气量目前都位居中国第一。随着开发不断深入，气田储量品质劣质化及未动用储量碎片化趋势明显，增加了未来效益开发的不确定性。为确保气田致密砂岩气藏的可持续效益开发，基于深化气田开发过程中所获得的地质与气藏工程认识的基础上，梳理了影响气田效益开发的影响因素，建立了该气田效益开发的技术对策。研究结果表明：①基于以经济产量为中心的评价模型对气田各区块经济效益进行实证分析，可以评价气田目前整体效益开发现状，指导未来整体开发方向；②为了支持气田致密气产业进一步发展，根据气田各区块效益评价，从地质和气藏工程的角度去寻求有效开发的配套措施，分类治理，分类施策，进而形成苏里格气田效益开发技术对策，实现气田持续经济有效开发。

At present Sulige Gas Field holds the distinction of being the largest in terms of natural gas reserves and annual production among tight sandstone gas reservoirs in China. However, as development progresses, there is a noticeable decline in the quality of gas field reserves and an increasing fragmentation of untapped reserves, escalating the uncertainties surrounding future development. This study builds upon a deepened geological and gas reservoir engineering comprehension acquired during earlier phases of gas field development. It methodically identifies the factors influencing the advantageous development of the gas field and formulates technical countermeasures to ensure its sustainable development. Key findings from the research include: ① An empirical analysis, centered on economic production, evaluates the economic benefits of each block within the gas field. This model assesses the current benefit status and directs future overall development strategies. ② To foster the continued advancement of the tight gas industry within the field, the study evaluates the benefits of individual blocks and explores supportive measures for effective development. These measures include classified management and specific technical strategies, derived from geological and gas reservoir engineering perspectives. This approach culminates in the formulation of technical countermeasures aimed at enhancing the effective development of Sulige Gas Field, thereby ensuring its continued economic viability.
