摘要
对于砂砾岩油藏高含水开发期,因储层非均质性的影响,注入水单层突进现象明显,使注入水利用率低,水驱效果较差。常规的注水方式和方法很难打破既成的单层突进的不利水驱现象。为此通过对油藏阶段开发矛盾的认识,在科学研究剩余油潜力后,在相关储层非均质和砂砾岩开发相关理论机理的指导下,采取了大量富有成效的现场实际注采工作,使一区三叠系油藏在进入"八五"后出现连续十年稳产。形成了一套砂砾岩油藏高含水期控水稳油的研究思路和技术对策,对今后该类油藏的开发提供了切实的指导。
For high containing water exploitation period of grit frame reservoir,because of non-uniformity,the onrush of water injected by single orientation, it is very limited for utilizing water injected and the effect of water drive is inadequate. However, it is very difficult to break such adverse phenomenon for ordinary ways of inject water. So, by dint of the knowledge of reservoir exploitation contradiction in different phase, after scientific investigation for potential of remanent oil,and guided by the correlative theory and mechanism of non-uniform reservior and grit frame reservoir exploitation,we adopt many effective on-the-spot work and have brought about continuous stable production of Triassic reservoir of block 1 for ten years. A suit of researchful thought and method about water control and oil stabilization in high water containing exploitation period of grit frame reservoir is formed,which proides practical direction for the same style reservoir exploitation.
