【摘要】：產(chǎn)液剖面測(cè)井技術(shù)是水平井測(cè)井開(kāi)發(fā)配套的重要技術(shù)之一,在水平井產(chǎn)液剖面測(cè)井中起著非常重要的作用。在指導(dǎo)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(cè)井的資料提供相關(guān)的依據(jù)。且水平井產(chǎn)液剖面測(cè)井資料與垂直井相比更加重要也更有價(jià)值。近年來(lái)隨著水平井的規(guī)模的不斷擴(kuò)大,相關(guān)問(wèn)題的不斷出現(xiàn),相關(guān)產(chǎn)液剖面測(cè)井資料的不完備對(duì)于水平井的開(kāi)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(cè)井系統(tǒng)利用成熟的油管輸送工藝進(jìn)行輸送,能夠準(zhǔn)確的到達(dá)目的層段,避免了常用牽引器在出砂過(guò)多的井內(nèi)爬行困難的問(wèn)題。流量的測(cè)量采用渦輪流量計(jì)和電磁流量計(jì)相結(jié)合的方式,電磁流量計(jì)有效擬補(bǔ)了返砂現(xiàn)象對(duì)渦輪流量計(jì)的影響。含水率的測(cè)量則采用了阻抗含水率計(jì)和筒狀電容含水率計(jì)相結(jié)合的方式,阻抗式含水率計(jì)在水相含率較低,即水相無(wú)法構(gòu)成連續(xù)相時(shí),會(huì)失去響應(yīng),結(jié)合筒狀電容含水率計(jì)的測(cè)量就可以有效的擴(kuò)大測(cè)量范圍。根據(jù)所要研究的內(nèi)容分別設(shè)計(jì)和建立了三種不同尺寸的仿真模型,并對(duì)模型進(jìn)行了合理的網(wǎng)格劃分。針對(duì)建立的模型利用Fluent仿真軟件在不同結(jié)構(gòu)、不同初始條件、不同流量以及含水率條件下的進(jìn)行油水兩相流在集流條件下的仿真計(jì)算。通過(guò)對(duì)仿真結(jié)果的對(duì)比分析,得出流量、含水率以及管道長(zhǎng)度對(duì)流體在流動(dòng)狀態(tài),界面高度以及達(dá)到穩(wěn)定狀態(tài)所需要的時(shí)間的影響,并進(jìn)行了實(shí)驗(yàn)驗(yàn)證。仿真結(jié)果為模塊化低產(chǎn)液水平井生產(chǎn)測(cè)井技術(shù)提供數(shù)據(jù)支持和技術(shù)指導(dǎo)。
[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.
