文明寨油田是一个复杂的断块油田，明六块是其主力区块，经过１５年的注水开发，层间矛盾突出，水驱动用程度低。该文从明六块储层物性认识入手，选择３口取心井的１８块岩心做了“五敏实验”，并利用井间示踪剂技术研究了储层物性。研究表明明六块在一定程度上存在着水敏、速敏、酸敏、弱碱敏和弱盐敏现象。得出该区块储层的临界流速为１１．８ｍ／ｄ。在此基础上提出了一系列提高采收率的工艺措施。通过实施，有效地控制了产量递减速度和含水上升速度，效果显著。明六块的开发实践，对于高含水期复杂断块油藏利用物性资料提高采收率具有重要的指导意义。
Wenmingzhai Oilfield is a complex fault block oilfield, the Ming six blocks is its main block, after 15 years of water development, prominent conflicts between layers, the low degree of water-driven. Beginning with the understanding of the physical properties of the six reservoirs, this paper selects “five sensitive experiments” from 18 cores of 3 coring wells and studies the physical properties of the reservoirs by using interwell tracers. The research shows that there are water-sensitive, speed-sensitive, acid-sensitive, weak-alkali-sensitive and weak-salt sensitive phenomena to a certain extent in Ming- The critical flow velocity of the reservoir is 11.8m / d. Based on this, a series of technological measures to enhance oil recovery are put forward. Through the implementation, effectively control the rate of decline in production and water-bearing rate of rise, the effect is significant. The development practice of Ming-6 blocks has important guiding significance for enhancing oil recovery by using physical data of complex fault-block reservoirs in high water cut period.
