【摘要】 王集复杂断块群油藏断裂系统复杂、物源多、地震品质较差,滚动勘探开发难度大,要想提高该区钻探成功率,必需做到地震地质有机衔接。首先是发挥专业优势,分别开展全区断裂系统空间解释及地质上的油组统层对比;其次地震地质紧密结合,在层位精细标定的基础上,利用地震地质连井大剖面相互验证,进一步确定断裂解释及油组界限的合理性;然后开展全区的精细构造解释,并结合测井、试油、试采及生产动态资料,对小断层、小断块及小砂体分布特点进行深入研究,搞清全区已知各类井的油水关系;最后研究总结全区油气分布及聚集规律,开展圈闭综合评价,提供钻探目标。这套研究方法科学指导了王集地区的滚动勘探开发部署,效果显著。更多还原

【Abstract】 As Wangji complex fault blocks oil reservoir was characterized by complex fracture system,multi-sources,poor seismic quality and great difficulties in progressive exploration and development,seismic-geologic research must be combined to improve the success rate of drilling in the area. First of all,carry out fracture system space interpretation and stratigraphic correlation;secondly,further determine fracture interpretation and rationality of oil group boundary based on fine horizon calibration by using seismic-geologic well-tie profile;thirdly,carry out fine structural interpretation of the whole area,make a further study on small fault,small fault-block and small sandbodies distribution in combination with logging,oil testing and dynamic production data,and make clear oil-water relation of different types of wells;finally,carry out comprehensive evaluation of traps and provide drilling targets based on the summary of hydrocarbon distribution and accumulation regularity.The facts prove the method provides guidance for progressive exploration and development and achieves good effect.更多还原
