摘　　要：丁家屋子断裂鼻状构造勘探开发目的层构造破碎复杂,在小于400 km2范围内共有大小断层306条,属于复杂断块油气藏。该区勘探目的层试油效果较好,但是试采产能低。在分析区块试油、试采资料的基础上,为了寻找试采效果差的原因,提出了在复杂断块非自喷井中进行延长测试的思路,通过实施,确定地层压力衰减,储层有效渗透率降低,污染加重是导致产能逐步降低的主要原因。The geological structure of Dingjiawuzi faulted nose-like structure is very crushed and complicated,in its area of 400 km2 there are 306 big or small faults.In this block,good flow rates were obtained during well testing but the productivities were low during production test.Extend testing was proposed to find out why it happened.Practice showed that the main reasons are formation pressure depletion,effective permeability lowering,and damage increasing.
