【摘要】：隨著國(guó)內(nèi)頁巖氣勘探開發(fā)力度不斷加大,為了降低開發(fā)成本、縮短投產(chǎn)周期、提高作業(yè)效率,“井工廠”開發(fā)模式被認(rèn)為是一種最佳模式。由于“井工廠”水平井的井口相對(duì)集中,大部分水平井都要設(shè)計(jì)為三維水平井,軌道設(shè)計(jì)的難度及其對(duì)鉆井風(fēng)險(xiǎn)及成本的影響都非常明顯。因此對(duì)“井工廠”水平井井眼軌道進(jìn)行優(yōu)選具有非常重要的意義。論文通過分析“井工廠”水平井的特點(diǎn),確定了三維三增水平井為“井工廠”水平井的一般形式,建立了三維三增水平井井眼軌道的批處理設(shè)計(jì)模型,并編制了水平井軌道批量設(shè)計(jì)程序。在此基礎(chǔ)上,對(duì)“井工廠”水平井鉆井成本的構(gòu)成進(jìn)行了分析,給出了與鉆井時(shí)間相關(guān)費(fèi)用和與井身結(jié)構(gòu)相關(guān)費(fèi)用的計(jì)算方法,形成了鉆井成本的預(yù)測(cè)方法,并編制了“井工廠”水平井鉆井費(fèi)用預(yù)測(cè)程序。在鉆井成本計(jì)算的基礎(chǔ)上,對(duì)“井工廠”水平井的鉆井風(fēng)險(xiǎn)問題進(jìn)行了評(píng)價(jià),針對(duì)井壁穩(wěn)定問題提出了一種利用鉆井液安全密度窗口評(píng)價(jià)井壁失穩(wěn)風(fēng)險(xiǎn)的風(fēng)險(xiǎn)系數(shù)計(jì)算方法;針對(duì)摩阻扭矩問題提出了一種利用摩阻扭矩計(jì)算結(jié)果評(píng)價(jià)摩阻扭矩超限風(fēng)險(xiǎn)的風(fēng)險(xiǎn)系數(shù)計(jì)算方法。在鉆井成本和風(fēng)險(xiǎn)評(píng)價(jià)的基礎(chǔ)上,對(duì)“井工廠”水平井不同參數(shù)條件下設(shè)計(jì)的一系列軌道進(jìn)行鉆井成本計(jì)算和鉆井風(fēng)險(xiǎn)評(píng)價(jià),依據(jù)一定的優(yōu)選原則就可以篩選出最合適的井眼軌道。在理論方法研究的基礎(chǔ)上,論文以一個(gè)包括四口水平井的“井工廠”水平井的井眼軌道設(shè)計(jì)為例,闡述了“井工廠”水平井井眼軌道優(yōu)化設(shè)計(jì)的詳細(xì)過程和步驟,最后的井眼軌道設(shè)計(jì)結(jié)果合理、可信,對(duì)“井工廠”水平井井眼軌道優(yōu)化設(shè)計(jì)具有一定的理論指導(dǎo)意義。
[Abstract]:With the increasing intensity of shale gas exploration and development in China, in order to reduce the development cost, shorten the production cycle and improve the operation efficiency, the "well factory" development model is considered to be the best one. Because the wellhead of "well factory" horizontal well is relatively concentrated, most horizontal wells should be designed as three-dimensional horizontal wells. The difficulty of track design and its influence on drilling risk and cost are very obvious. So it is very important to select the horizontal well trajectory in well factory. By analyzing the characteristics of horizontal well in "well factory", the paper determines the general form of "well factory" horizontal well, and establishes the batch design model of borehole track. A batch design program for horizontal well track is also developed. On this basis, the structure of drilling cost of horizontal well in "well factory" is analyzed, and the calculation method of drilling time related cost and well structure related cost is given, and the prediction method of drilling cost is formed. The program of drilling cost prediction for horizontal wells in well factory is also worked out. Based on the calculation of drilling cost, the drilling risk of horizontal wells in "well factory" is evaluated, and a calculation method of risk coefficient for evaluating the risk of wellbore instability by using the safe density window of drilling fluid is put forward. To solve the problem of frictional torque, a method for calculating the risk factor of friction torque is presented, which is based on the calculated results of friction torque to evaluate the risk of friction torque exceeding the limit. On the basis of drilling cost and risk evaluation, drilling cost calculation and drilling risk evaluation of a series of tracks designed under different parameters of horizontal well in "well factory" are carried out. According to certain optimal selection principle, the most suitable well track can be selected. Based on the research of theory and method, the paper takes the well track design of a horizontal well including four horizontal wells as an example, and expounds the detailed process and steps of the optimization design of the horizontal well trajectory in the "well factory". The result of the final well trajectory design is reasonable and credible, which is of theoretical significance to the optimization design of horizontal borehole track in "well factory".
