根据CB油田的实际情况,提出了以地震资料应用为基础,结合测井、地质、钻井等资料对油藏进行多层次综合研究的一套方法。主要包括:①利用综合参数法由地震信息预测砂岩发育区,指出勘探目标;②利用地震资料神经网络储层预测方法在砂岩发育区内确定油气富集带和部署探井;③在油气富集带内,利用地震和测井资料完成油井单个砂体的边界确定和厚度定量计算。利用这3 个层次的地震预测技术逐次解决了宏观的砂体分布、油气富集区带和单砂体定量解释。利用其预测结果所布置的2 口探井都见到了高产工业油流,取得了良好的效果
According to the actual situation of CB oilfield, a set of methods based on the application of seismic data and integrated logging, geology, drilling and other data to reservoir multi-level comprehensive study is proposed. Mainly include: (1) Predicting the sandstone development zone from the seismic information by using the integrated parameter method and pointing out the exploration target; (2) Using the seismic data neural network reservoir prediction method to determine the oil-gas accumulation zone and the exploration exploration well in the sandstone development zone; (3) , The seismic determination and well logging data are used to complete the boundary determination and the thickness quantitative calculation of a single sand body. Using these three levels of earthquake prediction techniques, the macroscopic distribution of sand bodies, the quantitative interpretation of oil-gas enrichment zones and single sand bodies are successively solved. Both of the two exploration wells arranged by the prediction result have seen high-yield industrial oil flow and achieved good results
