Geolog在大民屯凹陷元古界潜山储层评价中的应用

Application of Geolog in reservoir evaluation of Proterozoic Group buried hill exploration in Damintun Depression

近年来,辽河油田在大民屯凹陷元古界潜山勘探中不断取得突破,为了提高工区潜山油藏综合地质研究水平,确保“增储上产”目标的实现,测井-地质综合研究方面的新理论、新技术(包括软件)得到了广泛应用。充分利用Geolog软件平台中的各测井-地质综合研究模块,结合系统取心资料和试油资料,开展了大民屯凹陷元古界潜山油藏储层评价的研究工作,制定了该区岩性识别标准及储层划分标准,快速准确地识别元古界潜山地层岩性,并在岩性识别的基础上,进行储层划分,确定单井有效厚度,为进一步做好元古界潜山油藏综合地质研究工作及探明储量申报工作奠定了坚实的基础。

In the past few years,breakthrough was achieved continuously in Proterozoic Group buried hill exploration of Damintun Depression in Liaohe Oilfield.To improve the miscellaneous geologic investigation level in the work area and ensure the realization of the target of ”gaining more reserve and boosting the product”,new theories and technologies(including softwares)in well-logging and miscellaneous geologic investigation were applied extensively.different logging-miscellaneous geologic investigation models of Geolog software were sufficiently applied to the evaluation and study on the Proterozoic Group buried hill reservoir in Damintun Depression.Lithological discrimination standard and reservoir dividing standard were established.On the basis of lithological discrimination,the reservoir was divided and the effective thickness of single well was fixed.All above has been done for the further miscellaneous geologic investigations and proven reserves declaration in Proterozoic Group buried hill.
