RESEARCH AND APPLICATION OF THE STIMULATION IN LOW PERMEABILITY POOLS WITH ANOMOLY HIGH TEMPERATURE AND PRESSURE

The geological feature of low permeability pools with anomaly high temperature and pressure brings much more difficult and affects on the design of fracturing, selection of fracture material, implementation etc. In the past, by the limiting of knowledge and fracture technology level, this kind of reservoir was dealt with as normal low permeability pools in the fracturing design and implementation. So the effect was always poor. On the basis of deeply research of the reservoir feature and the fracture practice and the engineer condition of the oil field now, a set optimization fracture technology was provided that which suit this kind of reservoir. After using in Wendeng and Wennan Oilfield in Zhangyuan, the guide for similar reservoir was provided, which can improve simulate effect and prolong the valid deadline.
