利用多参数及地区经验评价大庆油田低孔低渗油气藏

EVALUATION OF THE LOW-POROSITY AND LOW-PERMEABILITY RESERVOIR OF DAQING OILFIELD USING "MULTIPARAMETER"AND " LOCAL RULE-OF-THUMB

本文综合应用“多参数”和“地区经验”研究了松辽盆地北部低孔、低渗油气藏地层岩石物性和含油性,确定出有效的分析参数和标准。这就较好地集中了专家的技能、经验、智慧和判断力,对这种地层作出了评价。经区内25口预探井、评价井实际应用,显示出较高的计算精度和较好的实用效果。

This paper deals with the study of rock's physical properties and oil-bearing extent of the low-porosity and low-permeability reservoir strata of northern Daqing Oilfield in Songliao Basin using ' muitiparametcr' and 'local rule-of-Ihumb' so as to determine the significant analytic parameter arid Us criteria applied. It proves that by so doing,the experts' know-how, their experiences, wisdom and ingenuity,and judgement could be,to a greater extent,pooled and hence brought into full play. Based on the strata of This, kind described above,an evaluation is made . As a result of utilizing the 25 exploratory wells and evaluation wells,higher calculation accuracy could have been ensured and fairly practical result are demonstrated.
