地层压力直接关系到油田各种措施的合理性及开发水平的高低。本文针对贝301区块在开发初期出现的地层压力下降快,注水开发受效后地层压力恢复缓慢、分布不均衡等问题进行了探讨,并分析了其原因,同时在此基础上结合该区块的地质特点,提出了相关的措施建议,对今后指导油田合理的注水开发,恢复地层压力有一定的指导意义。 Stratigraphic pressure is directly related to the rationality of various measures in the oil field and the level of development. In this paper, in order to solve the problems that the formation pressure of Bei 301 block decreases rapidly in the initial stage of development and the pressure of formation recovery is slow and the distribution is not balanced after the water injection development is effective, the reason is analyzed. At the same time, The geological characteristics of the oilfield, put forward the relevant measures and suggestions for the future guidance of the rational development of oilfield water injection, restoration of formation pressure has some significance.
