【摘要】：礁灰?guī)r儲層由于沉積時礁體縱向和橫向上的疊加,儲層以非均質(zhì)性強(qiáng)、橫向厚度變化快、鄰井對比差為特征。通過巖心資料對礁灰?guī)r儲層進(jìn)行描述是最直接最有效的手段,但是其受控于有限的井點,無法對儲層在橫向上的展布特征進(jìn)行連續(xù)的刻畫。在前人研究成果的基礎(chǔ)上,利用隨鉆電阻率成像測井結(jié)合巖心對南海珠江口盆地流花油田礁灰?guī)r儲層特征進(jìn)行了詳細(xì)分析和描述,并對裂縫及次生溶蝕進(jìn)行了定性和定量表征。結(jié)果表明,儲層裂縫發(fā)育規(guī)律性明顯,礁核部位裂縫最為發(fā)育,裂縫數(shù)量最多;礁后平臺裂縫發(fā)育一般,礁后斜坡裂縫發(fā)育良好。次生溶蝕分析表明,礁后平臺最為發(fā)育,其次是礁核,最后為礁后斜坡。結(jié)合實際產(chǎn)能情況,利用灰色關(guān)聯(lián)分析法對產(chǎn)能主控因素進(jìn)行分析,研究結(jié)果表明裂縫強(qiáng)度和次生溶蝕是影響流花油田產(chǎn)能的主控因素。
[Abstract]:The reef limestone reservoir is characterized by strong heterogeneity, rapid change of lateral thickness and poor correlation between adjacent wells because of the superposition of the reef body in longitudinal and lateral direction during deposition. It is the most direct and effective method to describe the reef limestone reservoir by core data, but it is controlled by the limited well point, so it can not continuously depict the horizontal distribution characteristics of the reservoir. On the basis of previous research results, the characteristics of reef limestone reservoir in Liuhua Oilfield of Zhujiang River mouth Basin in South China Sea are analyzed and described in detail by using resistivity imaging while drilling combined with core, and the qualitative and quantitative characterization of fractures and secondary dissolution are carried out. The results show that the development regularity of reservoir fracture is obvious, the fracture in the core of reef is the most developed, the number of fracture is the most, and the fracture in the back reef platform is common, and the fracture in slope behind the reef is well developed. The secondary dissolution analysis shows that the back reef platform is the most developed, the second is the reef core, and the last is the back reef slope. According to the actual productivity situation, the main factors of productivity control are analyzed by grey correlation analysis. The results show that fracture strength and secondary dissolution are the main factors affecting productivity in Liuhua Oilfield.
