蒙古林砾岩油藏属于低饱和底水油藏。由于油层厚度薄，油水粘度比大，储集层非均质性严重，油藏开发难度大，开发过程表现出油藏无水采油期短，综合含水上升快，产量递减快的特点。在深入研究油藏地质特点和动态特征的基础上，根据不同阶段的开发特点，采取了各种针对性强的开发技术和调整措施，达到了减缓含水上升速度，提高注入水波及体积，抑制底水锥进的目的。10年来，经过各项开发技术的综合运用，使油藏达到了较高的开发水平。较详尽地总结了该油藏的开发调整技术，为我国其它同类型油藏开发提供了经验。
Mongolian conglomerate reservoir belongs to low saturated bottom water reservoir. Due to the thin thickness of oil layer, large viscosity ratio of oil to water and serious reservoir heterogeneity, it is difficult to develop oil reservoirs. During the development process, it has the characteristics of short recovery period of water-free reservoir, quick rise of comprehensive water cut and rapid decrease of output. Based on the in-depth study of the geological and dynamic characteristics of the reservoir, various targeted development technologies and adjustment measures have been adopted according to the development characteristics at different stages, which have slowed down the rate of rise of water, increased the volume and volume of injected water, The purpose of water coning. In the past 10 years, after comprehensive utilization of various development technologies, the reservoir has reached a high level of development. It sums up the development and adjustment technology of this reservoir in more detail and provides the experience for the development of other similar reservoirs in our country.
