摘　　要：枣园油田枣35断块油藏是储集空间和构造类型复杂的火山岩稠油油藏,油田开发难度较大。由于油藏无边、底水,靠天然能量开采,加之地层能量不足,产量迅速下降,开发方式急需转换。开展了以补充地层能量和降粘为目的的水驱、热力采油、微生物驱等多种驱替方式的模拟及室内和现场试验,最终确定了适合该油藏的开发方式。The reservoir in fault block Zao35 oi Zaoyuan oilfield is a volcanic heavy oil reservoir with complex reservoir space and structure, and is difficult to develop. It has no edge and bottom water, and is recovered by natural energy. Oil production declined rapidly due to insufficient formation energy, and it is urgent to convert development scheme. Oil displacement modeling and indoor and field tests such as water flooding, thermal recovery and microbial drive for the purpose of supplementing formation energy and reducing viscosity have been conducted, and a development scheme suitable to this reservoir is finally determined.
