【摘要】：为了充分挖潜井间剩余油,提高储量动用程度,2012年开始在哈萨克斯坦K油田规模实施水平井。为了研究和评价应用水平井挖潜高含水油田剩余油潜力,应用地质、测井、油藏工程等多学科理论,优选层位,论证合理的水平段长度,分析水平井垂向位置以及合理产液量。在K油田剩余油丰度较高地区部署实施水平井38口。平均单井初期日产油17.9t,是同期直井的2倍以上,含水68.7%,低于全区平均含水20%,证实应用水平井技术开发高含水砂岩油田是可行的。
[Abstract]:In order to fully tap the remaining oil between wells and improve the level of reserve production, horizontal wells have been implemented on a scale in K Oilfield of Kazakhstan since 2012, and in order to study and evaluate the potential of exploiting potential remaining oil in high water-cut oil fields in horizontal wells. Applying the theory of geology, logging, reservoir engineering and so on, to optimize the horizon selection and to demonstrate the reasonable horizontal section length. The vertical position of horizontal wells and reasonable fluid production are analyzed. 38 horizontal wells are deployed in areas with high residual oil abundance in K oilfield. The average daily oil production in the initial stage of single well is 17.9 t, which is more than 2 times of that in the same period. The water cut of 68.7% is lower than the average water cut of 20% in the whole area, which proves that it is feasible to use horizontal well technology to develop high water-cut sandstone oil field.
