摘要/Abstract

摘要： 随着含油气盆地勘探程度的不断提高，油气区带与圈闭的定量评价成为油气勘探走向精细化、提高评价精度的必由之路。基于中国49个石油开发区带、44个天然气开发区带和360个圈闭的解剖与控制因素分析，综合不同类型油气区带和圈闭的控制因素，优选评价油气区带和圈闭有效性的关键参数，提出了基于评价参数网格化的油气区带与圈闭的无量纲定量评价方法。通过对油气区带和圈闭的评价参数进行无量纲归一化和网格化定量处理，计算被评价油气区带和圈闭的有效性评价参数，结合资源量可以确定油气区带和圈闭的有效性，实现油气区带与圈闭有效性的定量评价。塔里木盆地库车坳陷克深1—克深2圈闭的勘探实践验证了天然气区带与圈闭有效性定量评价思路和方法的有效性，在新方法的指导下于秋里塔格构造带中秋1井白垩系巴什基奇克组获得高产工业油气流。油气区带与圈闭有效性定量评价方法可大幅提高油气区带与圈闭评价的符合率，有效提高油气区带和钻探靶区的选择精度，为提高油气勘探的钻探成功率提供技术支撑。

Abstract: With the continuous improvement of the exploration of petroliferous basins, the quantitative evaluation of petroleum plays and traps is an essential way for the refined exploration of oil and gas and the accuracy of evaluation. Based on analyzing the control factors of 49 petroleum development zones, as well as 44 gas development zones and 360 traps in China, summarizing the controlling factors for different types of petroleum zones and traps, this paper selects the optimal key parameters for evaluating the effectiveness of petroleum zones and traps, and proposes a dimensionless quantitative evaluation method for petroleum zones and traps based on the gridding of evaluation parameters. Through the dimensionless normalization and gridding quantitative processing of the evaluation parameters of petroleum zones and traps, this paper calculates the effective evaluation parameters of the evaluated petroleum zones and traps. Further, in combination with resource extent, the effectiveness of hydrocarbon zones and traps can be determined, thus realizing the quantitative evaluation of hydrocarbon zones and traps. The exploration practice of Keshen 1 and Keshen 2 traps in the Kuqa depression of Tarim Basin has verified the effectiveness of the ideas and methods for quantitatively evaluating the effectiveness of gas zones and traps. Under the instruction of the new methods, high-yield commercial oil and gas flow has been obtained in the Cretaceous Bashjiqike Formation in Well Qiu-1 in the Qiulitage structural belt. The quantitative evaluation method for the effectiveness of hydrocarbon zones and traps can greatly improve the rate of agreement between the evaluations of hydrocarbon zones and traps, effectively increase the accuracy of selecting hydrocarbon zones and drilling targets, which provides technical support for improving the success rate of drilling in oil and gas exploration.

Key words: petroleum zone, petroleum trap, effectiveness, quantitative evaluation, Kuqu depression, Cretaceous
