摘　　要：相对主力油层而言,非主力层因其含油面积小、厚度薄、产能低,在油田开发初期未被列为重点开发对象.但随着油田开发时间的延长,主力油层进入高含水开发期,非主力油层逐渐转变为稳产的接替油层.以大情字井油田A区南部非主力层为研究对象,在分类评价的基础上,开展非主力层单独动用试验,落实非主力层产能及单独开发的可行性,通过充分挖掘非主力层的储量资源,取得了很好的试验效果.Corresponding to the main oil reservoirs, the non-main reservoirs are characterized by the following ob- jective reasons： small oil-beating area, thin thiekness, low productivity and so on, so the）＇ are not focused at the initial period of the oilfield development. But with the prolonged development, the essential reservoirs approach into high-watercut development period, the non-major reservoirs gradually transform into the main oil producing zones. Taking the non-essential reservoirs in Block A of South Daqingzijing Oilfields as the studying objects, on the, bases of the classification and evaluation, the individual developing test is conducted for the reservoirs, the productivity and feasibility are determined, and furthermore by means of the re-built set of well pattern, the reserves potentials are completely tapped. In a word, the much better test results are achieved.
