摘　　要：哈拉哈塘油田建产区块目前大部分缝洞带能量不足,地层压力下降快,自然递减大,为了实现区块的高效开发,减缓递减,需要补充能量进行注水开发。总结单井钻井放空漏失状况、酸压特征、开发试采特征、试井特征和测井,给出洞穴型、裂缝-孔洞型储层特征及判识标准;对哈拉哈塘油田不同典型缝洞体进行了数值模拟研究,给出哈拉哈塘油田定容洞穴、裂缝孔洞型、连通缝洞体合理的注水时机、闷井时间、注入速度、周期注采比。基于数值模拟结果和油藏地质特征,为井区下步的开发调整提供了依据。At the present, most of the fracture cavity system energy deficiency of the HLHT oilfield, the formation pressure drop quickly,and the natural decline of the production is very big.In order to realize the highefficient development of the main block and control the nat ural decline,the injection development is need to replenish energy.According to the reservoir characteristics,development production characteristics,drilling vent leakage situation,and characteristics of well test,the reservoir characteristics and recognizing standard is given for cavity system and fracture cavity system reservoir.The numerical simulation is done accord ing to different fracture cavity system typical well,the reasonable injection opportunity,well boring time, injection velocity and cycle injectionproduction ratio is given of single cave, fracture cavity system and connected fracture cavity system, providing basis for the next development of the main block.
