摘要
潜山油藏储集层具有裂缝发育非均质性强、内幕岩性杂乱等特点,为了提高地质导向技术在该类油藏水平井钻探中的作用,以辽河油田S 625区块元古界潜山为研究对象,应用录井、测井和物探手段,针对水平井钻井过程中潜山裂缝型储集层的识别方法进行研究,分别建立潜山地层岩性与裂缝识别的录、测井法和裂缝识别的地震反射特征法,解决了该潜山地质导向过程中井底轨迹钻遇层段判断、岩性识别、现场有利裂缝型储集层识别的主要问题,经过现场应用,取得了较好的效果。
Buried hill reservoirs have the characteristics of strong heterogeneity in fracture development and mixed and disorderly internal lithology.In order to improve the effect of geosteering technology in drilling horizontal wells in this type of reservoir,Proterozoic buried hill of S 625 block in Liaohe Oilfield was taken as the research object,mud logging,well logging and geophysical means were used to study the identification method of the buried hill fractured reservoirs during drilling horizontal wells.Mud logging and well logging methods for identifying the buried hill formation lithology and fracture and seismic reflection characteristic method of fracture identification were established respectively,they solve the problems of the drilled layer judgment for bottom hole trajectory,lithology identification and in-site favorable fractured reservoir identification.It achieved good results after field application.
