摘　　要：哈拉哈塘采油井见水特征受缝洞的空间发育特征、水体大小及接触关系等差异明显,但见水后产油量急剧降低,严重影响油井的开发效果。运用地球物理方法与录井响应特征,结合生产动态对油藏油水关系进行分析,建立了6种不同类型油藏模式;并通过分析出水井见水特征,结合地震、钻井、测井等资料,利用生产动态特征进一步分析油井的产水机理,分类型提出合理、有效的控水对策。对于暴性水淹型油井加强见水预警,及时调整工作制度,延长无水采油期;裂缝"水窜"台阶上升型无水期控制生产压差,含水停喷后提液生产;先升后降弱底水水淹型油井考虑关井压锥,压锥见效后,采取提液生产,哈拉哈塘奥陶系缝洞型油藏单井增油效果显著。Halahatang oilfield Ordovician reservoir is the typical complex fracture-vug reservoir.After water broke through,the production of oil well sharply drop ped down.Formation water problem is the outstanding issues of impeding crude oil production,restricting oil recovery.Think of the object of study formation water well in Halahatang oilfield,on the basis of concluding water production type,the water production mechanism of oil well is analyzed further with earthquake、drilling well、logging data,combining production characteristic.This provides reliable reference basis for reasonable and effective water control strategy,enhancing oil recovery.For sudden water influx oil well,water-breakthrough warning should be enchaned,adjusting working system timely and extending water free oil production period;for fracture 'water channeling ' step type,the production pressure differential in the water free oil production period should be controled and the liquid production should be enhanced when the oil well stops producting.For showing a trend from decline to rise and weak bottom water flooding oil well,shut-in coning technique should be considered firstly.If the water cut decreases with shut-in coning technique,the liquid production should be increased for this type well.
