生产数据估算无水碳酸盐岩油藏单井地质储量

Rationality Research of Using Tubing Pressure to Evaluate the Original Reserve of Carbonate Reservoir with No Water

碳酸盐岩油藏的开发过程中,因储层有较强的分隔性,开发初期无法准确有效的把握全区缝洞单元的分布规律,对未进行单井地层压力测试的生产井,评价单井地层能量没有一个行之有效的方法,本文将利用生产数据估算碳酸盐岩油藏单井地质储量,并论证其可行性,该方法计算简单方便,实用性强。

Because of high separability in carbonate reservoir,During the early development process of carbonate reservoir,we have no methods to exactly handle the rules of fracture-cave ditribution over the whole area in the beginning period.There is no effective way to assess the formation energy for failing to carry out dynamic pressure testing of the fracture-cave system.This paper will introduce a method of using production data to evaluate the energy of carbonate reservoirs and feasibility demonstration.
