红河油田长8油藏为超低渗致密砂岩油藏，高产水平井主要出现在裂缝发育区，能否刻画好裂缝是水平井能否成功的关键。本文以露头、岩心、测井、录井、三维地震资料为基础，通过对测井、地震相特征进行综合解释分析，对裂缝分布特征进行了精细描述。长8储层裂缝以高角度缝为主，平面上沿EW-SE向分布在玉都工区，东北部裂缝带较发育。该方法较好地解决了井位部署中裂缝识别和平面预测问题。
紅河油田長8油藏為超低滲緻密砂巖油藏，高產水平井主要齣現在裂縫髮育區，能否刻畫好裂縫是水平井能否成功的關鍵。本文以露頭、巖心、測井、錄井、三維地震資料為基礎，通過對測井、地震相特徵進行綜閤解釋分析，對裂縫分佈特徵進行瞭精細描述。長8儲層裂縫以高角度縫為主，平麵上沿EW-SE嚮分佈在玉都工區，東北部裂縫帶較髮育。該方法較好地解決瞭井位部署中裂縫識彆和平麵預測問題。

Chang 8 reservoir in Honghe oilfield is the lowest permeability of tight sandstone reservoirs,yielding horizon-tal wells mainly in the fracture zone,characterization of fracture is the key to the success of horizontal wells.In this paper, based on outcrop,core,logging,3D seismic data,by logging,seismic response characteristics launch comprehensive analy-sis explained,and finely desccibe distribution characteristics of the fracture.Chang 8 reservoir fracture is mainly high an-gle fracture.The plane along the southeast to the distribution located in the Yudu area,the northeastern fracture zone is de-veloped too.This method solves the fracture identification in the deployment wells and the plane prediction problem.As well as,this method has guiding significance for the deployment of the wells in the battle of North China.
