摘要
克拉玛依油田七西区克下组油藏位于准噶尔盆地西北缘,在克拉玛依市东30km处。,。该油藏为克-乌断裂、白碱滩南断裂及5075井逆断层所夹持的断层遮挡的构造岩性油藏,克下组储层为中等孔隙度、中等渗透率,孔隙连通性较好的储集层。×104t。
七西区克下组油藏主要采用直井,局部受地面条件限制,采用定向井。井距为230m的不规则反七点法注采井网,鉴于注热水可行性分析,建议注热水开发。共部署新井73口(采油井50口,注水井23口),抽油投产。老井利用6口(采油井5,注水井1口)。,×104t;平均单井日注水量20m3,×104m3。平均完钻井深1546m,×104m。测井系列选用521常规稀油测井系列,综合测井从井底测至八道湾组顶界以上30m,比例尺为1:200,并对油层孔、渗、饱参数进行解释评价。

ABSTRACT
Kelamayi oil field seven west of reservoir, located in the northwestern margin of junggar basin, in karamay east 30 k place. Things about km long, wide about km north and south. This reservoir as g-the fracture, white JianTan south fracture and 5075 Wells that the thrust faults the gripping the structure of the fault block lithologic reservoir, grams of reservoir for secondary porosity, permeability medium, pore connectivity good reservoir. Seven west estimate of the border region, expanding new reservoir geological reserves x 104 t.
.
Seven west grams of the reservoirs are mainly vertical Wells, local suffer ground conditions, the deviated. Well spacing for 230 m of the irregular at seven injection-production patterns s, given note hot water feasibility analysis, advice note hot water development. Altogether the deployment of new Wells 73 mouth (well include 50 mouth injection Wells, 23 mouth), sucker put into production. Using old left six mouth (well include 5, injection Wells 1 mouth). Design the single well productivity t/d, building the capacity of x 104 t; Average single well th injection 20 m3, the injected water volume x 104 m3. After an average of 1546 m deep drilling, drilling footage x 104 m. Logging series choose 521 conventional thin oil well logging series, comprehensive logging from the bottom to the top eight bay
