油层产能评价与预测是一项极富挑战性的课题,测井在产能评价与预测方面开展工作较早,技术方法较为成熟,而录井在这方面的研究与实践尚处于起步阶段。储集层原油的产出主要由其含油丰度和物性所决定,以这两项参数作为录井储集层产能评价与预测的基础数据,以冀中探区饶阳凹陷肃宁、大王庄、留路等地区为研究对象,通过建立以气测全烃为源数据的含油指数和以dcs指数为源数据的物性指数模型,并确定两指数的计算方法,最终根据含油指数与物性指数构建产能预测图板,实现了油层产能的初步评价与预测。近3年来对饶阳凹陷36口井120层进行了产能评价与预测,其中有14口井33层得到试油验证,总体吻合率接近80%。
Oil reservoir productivity evaluation and prediction is a very challenging issue. Logging works early in productivity evaluation and prediction, and the technical methods are mature. However, logging research and practice in this area is still in its infancy. The output of reservoir crude oil is mainly determined by its oil abundance and physical properties. Taking these two parameters as the basic data for capacity evaluation and prediction of reservoir logging, the data of Suning, Da Wangzhuang , Leaving the road and other areas as the research object. Through the establishment of oil-gas index based on total hydrocarbon gas as the source data and physical index model using dcs index as the source data and the calculation method of the two indices, the oil index and physical property index Capacity forecast chart, to achieve a preliminary evaluation and prediction of oil production capacity. In the recent 3 years, productivity evaluation and prediction of 120 wells in 36 wells in the Raoyang Sag have been carried out. Among them, 33 wells in 14 wells were tested for oil production and the overall anastomosis rate was close to 80%.
