济宁二井田边界断层与采区断层的规律性研究

井田主期构造控制着采区次级构造,济宁二井田地质构造复杂,中小断层发育,严重影响矿井的机械化生产,因此研究大中小断层之间的发育规律,对指导生产具有重要意义。论文根据生产过程获取的地质资料和井田构造特征及体系演化,对井田三采区中小断层的展布规律与边界大断层构造形态进行了对比分析,表明了边界断裂对采区断层具有一定的控制作用。

萨中开发区断层区套损特点新认识与开发应用

近年来随着薄差层开发力度加大,萨中开发区内的套损井数逐年增加。从套损区和套损层位的分布及从地质构造和地层应力的角度分析得出:套损区的规模和分布特点受断层的影响;断层区套损与断层滑动无关,是断层区压力不平衡的结果;受断层遮挡,大断距断层的两侧容易产生压力差异,对断层区地层应力场重新分布有影响,而重新分布的地层应力场产生应力集中是导致套损的直接原因。因此,在油田开发过程中应注意调节断层区的地层压力平衡,以防治断层区套损。

八里铺断层的富水性探测

济宁二号煤矿九采区北部边界巷沿八里铺断层煤柱平行布设,其断层落差大,本盘煤层与对盘奥灰"对接",为保证矿井安全开采,利用三极测深法和瞬变电磁法等综合物探手段,查明了该断层的位置和富水性.

Farewell faults in complex fault blocks with multi-technological integration

In the middle and second half of oilfield development,further exploration and development of petroleum reservoirs in complex fault blocks are major tasks.Based on the characteristics of fully developed farewell faults in the Wenweigu oil field and the data from 3D earthquakes,RFT,HDT and other techniques,farewell faults and their distribution were identified.Conformation of the fault blocks has been provided and the precision of describing the farewell faults improved.Research technology of farewell faults has applied these methods in this region.
