摘要 海拉尔盆地J油田储层类型多样,储层岩性复杂,以砂岩、砂砾岩、凝灰质砂岩和沉凝灰岩为主,而且储层物性变化较大,使常规测井资料难以准确划分储层和储层评价。结合研究区地质特点,应用试油法、经验统计法、含油产状法等方法来确定不同层位储层物性下限标准。以物性下限标准为基础,优选对储层岩性、物性、含油性敏感的测井曲线,建立有效厚度划分的电性标准。提高该区开发井有效厚度的测井解释精度,满足油田开发的需要。 The geological structure is extremely complex in the J oilfield in hailaer basin,China.The reservoir zones are various.The lithology is mainly composed of sandstones,sandy conglomerates,tuffaceous sands and sedimentary tuff.Besides,the physical property in the reservoirs is always changing.As a result,it's quite difficult to exactly divide and evaluation the reservoirs with conventional logging data.Taking the geological features of the study area into consideration,the lower limit standard of the physical property in different reservoir by using,formation test method,experiential statistical method,oil-bearing occurrence method and other methods is identified.What's more,on the basis of the lower limit standard,the electrical standard is established to divide the effective thickness of reservoirs by carefully choosing those logging curves that are sensitive to the lithology,the physical property and the oil bearing property.This is definitely to improve the logging interpretation accuracy on the effective thickness in this area,which consequently contribute to developing the oilfield.
