老井复查技术在苏北盆地HY区块的应用

Application of Old Well Review Technology in HY Block in Subei Basin

苏北盆地海安凹陷勘探开发程度较低,已有成熟油田为曲塘次凹张家垛圈闭的张家垛区块以及曲塘圈闭的曲塘区块,而位于海北次凹的HY区块,从生、储、盖到圈、运、保所有地质资料均表明,该地区也具备良好的油气地质条件,预示着有较好的油气勘探前景。因此,针对外围区块老井开展了此次老井复查,寻找有利区块。

The degree of exploration and development in the Haian Sag of the Subei Basin is relatively low.The existing mature oilfields are the Zhangjiaduo block in the Zhangjiaduo trap of the Qutang sub-sag and the Qutang block in the Qutang trap,and the oilfields are located in the Haibei sub-sag.In HY block,all the geological data from generation,storage,capping to circle,transportation,and preservation indicate that the area also has good oil and gas geological conditions,which indicates a good prospect for oil and gas exploration.Therefore,the old well review was carried out for the old wells in the peripheral blocks to find favorable blocks.
