摘要(Abstract)：

针对砂泥薄互型致密油储层水平井设计及导向跟踪的难题,选取松辽盆地三肇凹陷扶余油层F区块为靶区,综合考虑构造、储层、砂体、物性及含油性等地质资料,优选构造有利的地垒,沉积砂体规模大和试油产量高的区块部署水平井,通过制定精细的水平井井位部署流程——油层精细划分、地震储层预测、三维地质建模和水平井参数设计,完成9口水平井部署;通过跟踪对比确定标志层、及时调整控制入靶点以及采用三维模型控制法、地震储层预测法、综合控制法进行实时地质跟踪导向。结果表明,9口井砂岩钻遇率为91.2%,含油砂岩钻遇率为88.1%。
Aiming at the difficulties in designing, geosteering and tracking the horizontal wells in thin sand-mud interbedded tight oil reservoirs, Block F of Fuyu oil reservoirs in Sanzhao Sag of Songliao Basin was selected as the target area, by means of the comprehensive analysis of the structure, reservoir, sandbody, physical property and oil-bearing property, the favorable horst in the structure was optimized, and horizontal wells were deployed in the blocks with a large-size sedimentary sandbody and high-production oil test, with the help of the compiled fine flowsheet of the horizontal well location deployment,namely finely dividing the oil layers, predicting the seismic reservoir, 3 D geological modeling and horizontal well parameter designing, total nine horizontal wells were deployed.Through tracking and contrasting, the marker beds were determined, the target point was timely adjusted and controlled, and moreover the real-time tracing and geosteering were engaged by means of three-dimensional model controlling method, seismic reservoir predicting method and comprehensive controlling method. The results show that the sandstone drilling ratios in the nine wells are up to 91.2%,and the ratios of penetrating the oil-bearing sandstone can reach 88.1%.
