摘　　要：合理的工作制度是实现缝洞型油气藏高效开发的关键,而工作制度与储层类型有着密不可分的联系。以塔中I号气田试采井为基础,对储层类型与初期产量、产量递减、见水特征、流压及采收率等试采特征的关系进行了研究,并在此基础上对塔中I号气田合理工作制度的制定进行了评价,结果表明储层类型不同造成试采特征差别很大,裂缝—溶洞型储层初期产量高,但后期递减快,稳定期短,流压下降幅度较大,出水类型为暴性水淹;而裂缝-孔洞型储层初期产量较低,后期低产稳产,稳产期较长,流压相对平稳,出水类型为间歇产水。而试采特征同时体现了储层的特征,据此可以制定科学的工作制度,实现油气藏的高效开发。The key to achieving high-efficiency development of oil and gas is to formulate a reasonable work system,which is closely related to reservoir type f or vuggy fractured reservoir.This paper studies the relationship between reserv oir types and production testing characteristics such as initial production,pro duction rate decline,water cut,flow pressure,recovery ratio,etc.for Tazhong-I gas field,and on this basis,it evaluates the work system of production test ing wells in Tazhong-I gas field.The results show that distinct reservoir types demonstrate different production testing characteristics： high initial producti on,quick decline rate,short stable production period,great decrease of flow p ressure,and sudden water flooding for facture-caved type of reservoir.While fo r facture-vuggy type of the reservoir,the features illustrate low initial produ ction,stable production rate and flow pressure,and intermittent water producti on.Furthermore,the production testing characteristics also show the characteri stics of reservoir.This,accordingly,suggests scientific work system is able t o realize the better development.
