塔河油田碳酸盐岩油藏能量指示曲线模型建立与应用
|
摘要
塔河油田碳酸盐岩油藏以溶洞型-定容储集体为主,目前确定该类储集体地质储量的方法较多,但多数方法都存在一定缺陷,而且直接反映地层能量大小的公式也不多。在物质平衡方程的基础上,考虑原始地层水体能量,运用溶洞型-定容体体积平衡原理,建立地层压力与累计产液量之间的关系表达式,以此提出能量指示曲线的概念,用于直接反映地层能量大小,并求解地质储量。以塔河油田跃进区块为例,运用能量指示曲线的不同形态,分别选取区块内YJ2-3、YJ3井进行评价,重新核定油井的地质储量,评价地层能量大小。
Carbonate reservoir in Tahe Oilfield is mainly of karst-cave constant-volume reservoir bodies. Now there are many ways to determine the geological reserves of this kind of reservoir bodies,but most methods have a certain defects and there are not many formulas for the direct response to the formation energy. Based on the material balance equation,considering the energy of the original formation water body,the relationship representative between the formation pressure and cumulative liquid production was established by the balance principle of karst-cave constant-volume body. Thus the concept of the energy indicating curve was proposed to directly reflect the size of the formation energy and to solve the geological reserves. Taking Yuejin Block in Tahe Oilfield as an example,Well YJ2-3 and Well YJ3 in the block were selected and evaluated respectively with the help of different forms of the energy indicating curve,the geological reserves of the oil wells were rechecked and the formation energy was evaluated at last.
