【摘要】：產(chǎn)液剖面測井技術是水平井測井開發(fā)配套的重要技術之一,在水平井產(chǎn)液剖面測井中起著非常重要的作用。在指導壓裂和堵水以及優(yōu)化注采方案等方面的作業(yè)都需要產(chǎn)業(yè)剖面測井的資料提供相關的依據(jù)。且水平井產(chǎn)液剖面測井資料與垂直井相比更加重要也更有價值。近年來隨著水平井的規(guī)模的不斷擴大,相關問題的不斷出現(xiàn),相關產(chǎn)液剖面測井資料的不完備對于水平井的開發(fā)的影響已經(jīng)日益突出。本課題所研究的模塊化水平測井系統(tǒng)利用成熟的油管輸送工藝進行輸送,能夠準確的到達目的層段,避免了常用牽引器在出砂過多的井內爬行困難的問題。流量的測量采用渦輪流量計和電磁流量計相結合的方式,電磁流量計有效擬補了返砂現(xiàn)象對渦輪流量計的影響。含水率的測量則采用了阻抗含水率計和筒狀電容含水率計相結合的方式,阻抗式含水率計在水相含率較低,即水相無法構成連續(xù)相時,會失去響應,結合筒狀電容含水率計的測量就可以有效的擴大測量范圍。根據(jù)所要研究的內容分別設計和建立了三種不同尺寸的仿真模型,并對模型進行了合理的網(wǎng)格劃分。針對建立的模型利用Fluent仿真軟件在不同結構、不同初始條件、不同流量以及含水率條件下的進行油水兩相流在集流條件下的仿真計算。通過對仿真結果的對比分析,得出流量、含水率以及管道長度對流體在流動狀態(tài),界面高度以及達到穩(wěn)定狀態(tài)所需要的時間的影響,并進行了實驗驗證。仿真結果為模塊化低產(chǎn)液水平井生產(chǎn)測井技術提供數(shù)據(jù)支持和技術指導。
[Abstract]:Fluid production profile logging technology is one of the important techniques for horizontal well logging development. Production profile logging plays a very important role in horizontal well logging. In guiding fracturing and water shutoff and optimizing injection and production plan, the relevant data of industrial profile logging are needed. Surface logging data are more important and valuable than vertical wells. In recent years, as the scale of horizontal wells continues to expand, With the emergence of related problems, the influence of incomplete logging data on horizontal well development has become increasingly prominent. The modularized horizontal logging system studied in this paper uses mature tubing transportation technology for transportation. It can reach the target layer accurately and avoid the difficulty of crawling in the well with the usual tractor. The flow rate is measured by the combination of turbine Flowmeter and electromagnetic Flowmeter. The effect of sand return phenomenon on turbine Flowmeter is effectively supplemented by electromagnetic Flowmeter. The water content is measured by the combination of impedance moisture content meter and tubular capacitance moisture meter, and the impedance moisture content meter has lower water content in water phase. That is, when the water phase can not form a continuous phase, it will lose its response, and the measurement range can be effectively expanded by combining the measurement with a tubular capacitance moisture meter. Three simulation models with different sizes are designed and built according to the contents of the study. According to the model, the Fluent simulation software is used in different structure and different initial conditions. The simulation calculation of oil-water two-phase flow under the condition of different flow rate and water content is carried out under the condition of gathering flow. Through the comparison and analysis of the simulation results, it is concluded that the flow rate, water cut and pipeline length have effect on the flow state of the fluid. The effect of interface height and the time required to achieve stable state is verified by experiments. The simulation results provide data support and technical guidance for modularized production logging technology of low liquid horizontal wells.
