【摘要】：深水淺層鉆井液安全密度窗口窄,給深水淺層鉆井設(shè)計(jì)和工程安全帶來極大挑戰(zhàn)。根據(jù)深水淺層地層特征,運(yùn)用四參數(shù)流變模型進(jìn)行了波動壓力計(jì)算,在此基礎(chǔ)上考慮深水淺層隔水管安全余量和淺層地質(zhì)災(zāi)害安全余量建立了深水淺層鉆井液安全密度窗口確定方法。以我國南海鶯瓊盆地YC1井為例,計(jì)算分析了深水淺層鉆井液安全密度窗口變化規(guī)律,結(jié)果表明隔水管安全余量、淺層安全余量對深水淺層鉆井液安全密度窗口影響較大。根據(jù)上述結(jié)果,提出了利用雙梯度鉆井技術(shù)(DGD)解決鉆井液安全密度窗口窄的方法,可為深水鉆井設(shè)計(jì)提供參考。
[Abstract]:The narrow safe density window of deep water shallow drilling fluid brings great challenge to the design and engineering safety of deep water shallow drilling. According to the characteristics of deep water shallow formation, the wave pressure is calculated by using four parameter rheological model. On this basis, considering the safety allowance of deep water shallow riser and shallow geological hazard safety allowance, the method of determining the safe density window of deep water shallow drilling fluid is established. The YC1 well in Yingqiong Basin, South China Sea, is taken as an example. The variation law of the safe density window of deep water shallow drilling fluid is calculated and analyzed. The results show that the safety allowance of riser and shallow layer have great influence on the safe density window of deep water shallow drilling fluid. This paper presents a method to solve the problem of narrow window of safe density of drilling fluid by using double gradient drilling technology, which can be used as a reference for deep water drilling design.
