一、问题的提出 多年来,石油勘探开发技术人员就注意到,许多油气田、油气井没有在产层所具有的产能水平上出产油气,其实际产量比产层原始渗透率所指示的油气井应该具有的产量低。一些油气井产量递减很快,造成这些油气田的异常早期衰竭,严重降低了这些油气田的最终采收率。这使成百万吨的极为宝贵的石油仍然留在地下而不能被采出。这些巨 First, the problem raised Over the years, oil exploration and development technicians have noticed that many oil and gas fields, oil and gas wells do not have the production capacity of the production level of oil and gas production, the actual output than the original production of oil and gas wells should indicate the original permeability should Has a low yield. The well-declining production of some oil and gas wells has resulted in anomalous early depletion of these fields, severely reducing the ultimate recovery of these fields. This keeps millions of tons of extremely valuable oil underground and can not be mined. These giant
