摘　　要：四川盆地内具有较为丰富的低效天然气资源,但转化率很低。为提高四川盆地低效油气藏的勘探开发成功率,充分利用现有成熟的勘探技术,积极开展了四川盆地低效油气藏勘探配套技术研究。应用地质、物探、测井、录井的新认识、新技术、新方法对各区域和构造的报废井和老井分门别类开展评层选井论证,利用裂缝储层综合描述、AVO烃类检测、砂体描述、缝洞预测等技术,结合录井、测井资料开展综合研究。在区块整体勘探方面,针对各区块均为浅层的特点,应用成熟勘探技术加强研究工作,取得了很好的成果。运用研究成果及认识,已在花果山、苏码头、盐井沟、观音寺、白马庙、大塔场等构造和地区拟定了新钻井目标30个,截至目前勘探成功率达93.3%。Low-efficiency gas resources are relatively abundant in the Sichuan basin,but their conversion rate is very low.Currently available and mature exploration techniques are fully utilized to improve the success rate of exploration and development of this kind of reservoirs in the Sichuan basin.New understandings,new techniques,and new methodologies in respects of geology,geophysical prospecting and logging are used to evaluate the abandoned wells and old wells in each block.Comprehensive study is carried out by integrating various techniques such as description of reservoir and fracture,AVO hydrocarbon detection,sandbody characterization and fracture-cavity prediction and combining with various logging data.Given all the blocks are shallow in burial depth,the mature exploration techniques are used to enhance research,achieving satisfactory effects in respect of overall exploration.Based on the study results,30 new drilling targets are selected in several blocks including Huaguoshan,Sumatou,Yanjinggou,Guanyinsi,Baimamiao and Datachang.Up till now the successful rate of exploration is up to 93.3%.
