塔南油田19-14断块为低渗透油藏,在其开采过程中要考虑开采方式,为确定是否应采用天然能量开采,能否达到预期的效果,需要确定断块的天然能量,其中边底水能量不容忽视,即水体倍数的大小.以塔19-14断块的边底水能量为研究对象,根据非稳定状态法,计算塔南油田19-14断块的边底水能量,为不活跃型,不适合采用边底水能量开采. The block 19-14 in Tannan Oilfield is a low permeability reservoir. Mining methods should be considered during the mining process. To determine whether natural energy recovery should be used to achieve the desired effect, the natural energy of the fault block needs to be determined. The bottom water energy can not be neglected, that is, the size of the water body.Based on the energy of the edge water of the block 19-14 fault block, the edge water of 19-14 fault block in Tannan oilfield is calculated according to the unsteady state method, which is Not active, not suitable for the use of edge water energy extraction.
