摘　　要：石西地区八道湾组已对12口井、21个层位进行了试油,在射孔井段较大的条件下,各井段产液量普遍极低,且无一口井获得工业油气流。在老井油层复查中,共发现6口井有油层,但都位于圈闭边缘或圈闭外。对石西地区八道湾组进行了孔隙度和渗透率分析,结果表明八道湾组属于低孔特低渗至特低孔超低渗储层,具有较强的非均质性,导致油气在储层内的侧向运移不通畅。In Badaowan Formation,12 wells and 21 oil layers are tested under the conditions of large perforated interval,every interval has generally low liquid producing capacity,and no well is obtained commercial oil and gas flow.By re-examination of oil layer,6 wells found oil layer,but the wells are all located in the ring or outside the trap.By analyse of the specimen's porosity and permeability,the quality of Badaowan Formation reservoir is low porosity and ultra-low permeability to ultra-low porosity and super-low permeability,the heterogeneity is stronger,the lateral migration of gas and oil in the reservoir is unsmooth.
