南东过区块属于低渗透油层,储层物性差,通过采用先进的分层测压技术,取得了较好的效果,也为算他低渗透油层的开发调整提供了指导与借鉴。萨尔图中部油田自1960年投产以来,采用多套井网分步动用开发,经历了多次调整,各类油层得到较好的动用,但由于储层沉积构造的复杂性和成岩作用的多样性,油层在平面上和纵向上具有很强的非均质性,同时井网之间的相互作用、相互影响,导致高含水后期区域内平面和层间压力分布不均衡,不仅影响了油田开发效果,而且加大了后期调整挖潜和套损防治的难度。2000年以来,南东过采用先进的分层
South East over the block belongs to low permeability reservoir, poor reservoir properties, through the use of advanced stratified pressure measurement technology, and achieved good results, but also for his low permeability reservoir development and adjustment provide guidance and reference. Since it was put into operation in 1960, the central Saertu oilfield has adopted multiple well patterns and developed in a step-by-step manner. It has undergone many adjustments and various types of oil layers have been well utilized. However, due to the complexity of reservoir sedimentary structures and diversification of diagenesis In addition, the interaction and interaction between well patterns cause the unbalanced distribution of pressure between the plane and the interlayer in the later stage of high water cut, which not only affects the development of the oilfield Effect, but also increased the latter part of adjustment and tapping potential to prevent the difficulty of prevention and control. Since 2000, South East has adopted advanced stratification
