| 摘 要： | 低渗透油藏储层物性较差，通常油层在酸化压裂等工艺技术措施下，才可产出工业油流，对低渗透油藏有效储层进行测井解释较为困难。从冷家堡油田冷46区块的油藏特征出发，建立了一套有效厚度下限标准研究方法。为检测油层有效厚度划分精度，在取心井中选取5口井进行岩心厚度与测井厚度对比，层划准率达100％。并据此标准划分39口单井有效厚度，有效地保证油层射孔，为注水开发提供可靠的依据。

| Abstract: | Physical property is bad in low permeability reservoir, and commercial oil flow can＇t be obtained without acid fracture process. Log interpretation is difficult for productive reservoirs. Based on reservoir characteristics of Leng 46 block in Liaohe Oilfield, a set of method studied on net pay thickness standard was established. In order to detect dividing precision of net thickness, 5 wells in coring wells were selected to compare with core thickness and log thickness. Dividing precision ratio is 100 %. The net thickness of single well had been determined in 39 wells, and it ensured success of layer perforation effectively and provided reliable evidence for waterflood development. |
