A区块于2009年开展一次加密井网两套层系互换综合挖潜现场试验,通过转变开采层系,改变液流方向,提高波及体积,探索特高含水期改善一次加密井网开发效果的方法。互换开始后取得一定效果,但单井效果差异较大,通过分析得出单井射孔对应性、注水状况不同以及所处井位的井网关系是影响单井生产情况的主要因素,并确立适合层系互换的射孔原则、井网部署原则及注水调整原则,对为进一步改善该区块试验效果提供依据。
A Block In 2009, an in-situ test of two sets of wellbore interchanges in an integrated well network was carried out. By changing the production strata, changing the flow direction, increasing the volume and exploring the effect of improving the wellbore development in the ultra-high water cut stage method. After the beginning of the exchange, some effects were obtained, but the single-well effect was quite different. Through analysis, it was found that the single-well perforation correspondence, the different water injection conditions and the well pattern of the well are the main factors affecting single well production. The perforation principle, well pattern deployment principle and waterflooding adjustment principle that are suitable for the exchange of layers are established to provide the basis for further improving the test results of the block.
