摘要/Abstract

摘要： 隐蔽油气藏已成为渤海湾盆地油气勘探的重点，其中岩性油气藏更是今后增产稳储的重要目标。近几年的勘探实践表明，岩性圈闭的含油性变化较大，其含油性和充满度大小的估算已成为油田勘探决策、井位部署及油田开发过程中不可缺少的重要技术。在地质统计和层次分析的基础上，找出了控制东营凹陷岩性油藏含油性的主要地质因素，并对其定量化，运用多元线性回归方法建立了东营凹陷各构造区带岩性圈闭充满度的数学预测模型。模型可靠性的验证结果表明，80%的岩性圈闭充满度的理论值与实测值吻合较好，说明此种定量预测的方法是可行的。

Abstract: Subtle oilgas pool has been the explorative emphases in Bohai bay basin and the lithologic pool is the important aim for reserves improvement. But the exploration in recent years indicated that the different petroliferous quality of lithologic trap is very distinct. The estimate that if the trap is oilbearing or not and how much is the fullness degree of lithologic trap has been indispensably important technology in the whole course of decisionmaking of exploration， arrangement of well position and exploitation of oil field. On the basis of geological statistics and AHP(analytic hierarchy process) analyses of 236 lithologic traps of Dongying depression， the main controlling factors of reservoir formation are found out and rationed. Then making use of multilinearity regress method， the fullness degree forecast models of lithologic trap at each structural zone in Dongying depression are established. The validation results of this forecast models indicate that 80% forecast fullness degree of lithologic trap is consistent to the factual value，implying that the forecast method can be used in oil and gas prospection.

Key words: Bohai bay basin, lithologic reservoir, petroliferous property, fullness degree, quantificational forecast
