成熟区岩性油气藏勘探再认识 总被引：1，自引：1，他引：0
大港油田历经40多年的勘探,已经进入成熟区岩性油气藏勘探阶段。成熟区的油源、储集、圈闭等条件均较优越,但成熟区构造及油藏关系复杂,因此成熟区勘探应采用斜坡区岩性勘探的思路和工作流程,重新认识和评价成熟区的分析研究工作,要在充分利用成熟区丰富钻井资料的基础上,开展储层精细研究,包括层序划分、岩相识别以及剖面上和平面上的储层刻画。实践证明,对成熟区岩性油气藏勘探的再认识应用效果十分明显,从而打开了成熟区勘探的新局面。 相似文献

The dynamic characteristics of acceleration autopilot and attitude autopilot are discu.ssed in detail. Also, a comparison study was made between these two different types of control schemes for guidance loop. By means of simulation, it is concluded that the guidance accuracy is mainly determined by the slowest subsystem among different system dynamics. For air-to-ground missiles, with limited terminal guidance time, the control scheme of acceleration autopilot combined with proportional navigation guidance （PNG） law is the better choice. 相似文献
