【摘要】：海上油田示蹤劑測試成本高、測試資料少,應(yīng)用示蹤劑產(chǎn)出曲線評價井間動態(tài)連通性較為困難。根據(jù)現(xiàn)場監(jiān)測獲得的產(chǎn)出聚合物數(shù)據(jù),結(jié)合數(shù)值模擬技術(shù)進(jìn)行產(chǎn)出聚合物敏感性分析,并在此基礎(chǔ)上對單井聚合物產(chǎn)出曲線擬合,利用CMG數(shù)值模擬軟件的多組分定義功能實現(xiàn)了聚合物產(chǎn)出方向的識別及產(chǎn)出量的劈分。應(yīng)用該方法評價了L油田A10注聚井組的井間動態(tài)連通性,并根據(jù)井間連通情況,提出了相應(yīng)調(diào)整對策。應(yīng)用結(jié)果表明:注水井A10與生產(chǎn)井A44井間見聚速度快、產(chǎn)出聚合物多,存在優(yōu)勢滲流通道,再結(jié)合生產(chǎn)井A44產(chǎn)液剖面測試結(jié)果,建議對A10井調(diào)剖、A44井卡水,預(yù)計措施實施后A44井產(chǎn)量翻番,增油降水效果明顯。
[Abstract]:The testing cost of tracer in offshore oilfield is high and the test data are few. It is difficult to evaluate the dynamic connectivity between wells by using tracer output curve. Combined with numerical simulation technology, the sensitivity analysis of polymer production is carried out, and on the basis of this, the polymer output curve of single well is fitted. The multi-component definition function of CMG numerical simulation software is used to identify the direction of polymer production and split the output. The dynamic connectivity between wells of A10 polymer injection well group in L oilfield is evaluated by using this method. According to the condition of inter-well connectivity, the corresponding adjustment countermeasures are put forward. The application results show that the convergence rate between water injection well A10 and production well A44 is fast, the polymer production is more, and there is an advantage seepage channel. Combined with the test results of production well A44 production profile, it is suggested that the oil production of well A44 should be doubled and the effect of increasing oil and precipitation should be obvious after the implementation of the measures for profile control and profile control of well A44.

【正文快照】： 0引言L油田主體塊為受巖性影響的構(gòu)造層狀油氣藏。初期采用近似反九點井網(wǎng)注水開發(fā),自2006年開始單井注聚,2007年擴(kuò)大至Ⅱ油組主體區(qū)注聚。目前暴露的問題是同一注聚井組內(nèi)各井含水率差異大,產(chǎn)聚質(zhì)量濃度各有高低,采油井見效差異很大。要解決此問題,就需要定量表征油水井間的
