【摘要】：隨著石油鉆井技術(shù)的發(fā)展,水平井鉆井技術(shù)已經(jīng)成為當(dāng)今石油工業(yè)一項比較成熟的技術(shù),并被廣泛應(yīng)用于油田開發(fā)建設(shè)。將水平井技術(shù)同叢式井技術(shù)相結(jié)合,可以綜合兩大鉆井技術(shù)的優(yōu)勢,增加油藏開發(fā)面積,減少地面井場建設(shè)占地,方便采油集輸管理。BA油田石油儲量豐富,是世界幾大原油輸出地區(qū)之一。該油田項目也是中石油在海外幾個比較大的項目之一。該地區(qū)大部分為三維叢式水平井,具有以下施工難點:地層復(fù)雜,可鉆性差;壓力關(guān)系復(fù)雜,泥漿密度窗口窄;直井段防碰問題突出,軌跡控制難度大等。本文通過對BA油田三維叢式水平井工藝技術(shù)的研究與應(yīng)用,針對三維叢式水平井軌跡控制難度大、施工地區(qū)地質(zhì)條件復(fù)雜和機(jī)械鉆速慢等技術(shù)難題,開展了井身剖面優(yōu)化設(shè)計與三維軌跡精確控制、MWD和LWD儀器運用與改進(jìn)和鉆井技術(shù)等方面技術(shù)攻關(guān),在三維叢式水平井井身軌跡控制、減少井下復(fù)雜情況和平臺叢式水平井安全技術(shù)等方面取得了一定突破,取得了良好的科研技術(shù)實踐效果和經(jīng)濟(jì)與社會效益,達(dá)到了三維叢式水平井技術(shù)國際水平。本文研究內(nèi)容旨在總結(jié)三維叢式水平井技術(shù)經(jīng)驗,為在該地區(qū),乃至其他國家和地區(qū)應(yīng)用該技術(shù),形成技術(shù)模板,作為國內(nèi)一項比較成熟的鉆井技術(shù)應(yīng)用于石油鉆井行業(yè)。該項課題的研究,實現(xiàn)了平臺叢式水平井在BA油田首次成功應(yīng)用;形成了一套三維橫向大跨度水平井井眼軌跡精確控制技術(shù);實現(xiàn)了平臺叢式水平井安全鉆井,鉆井周期縮短10%以上,形成了技術(shù)模版。本文研究過程與整個BA定向井項目基本同步,目前已完成該項目一期工作量,順利完成了全部39口井的施工,為其他項目開發(fā)提供了參考資料和技術(shù)模版。該技術(shù)必將在該地區(qū)其他項目中規(guī)模推廣應(yīng)用。三維叢式水平井技術(shù)成功應(yīng)用,也使中國定向井品牌在該地區(qū)乃至整個海外定向井服務(wù)市場更加響亮。
[Abstract]:With the development of petroleum drilling technology, horizontal well drilling technology has become a relatively mature technology in petroleum industry, and has been widely used in oilfield development and construction. Combining horizontal well technology with cluster well technology can integrate the advantages of two drilling technologies, increase reservoir development area, reduce ground site construction, and facilitate oil recovery management. BA oilfield is rich in oil reserves. It is one of the major crude oil export regions in the world. The oil field project is also one of PetroChina's several relatively large overseas projects. Most of the wells in this area are three dimensional cluster horizontal wells, which have the following difficulties: complex formation, poor drillability, complicated pressure relation, narrow mud density window, prominent collision prevention problem in the straight well section, difficult trajectory control and so on. In this paper, through the research and application of 3D bunching horizontal well technology in BA oilfield, aiming at the technical problems such as difficult trajectory control, complex geological conditions and slow drilling speed in the construction area, etc. The optimization design of wellbore profile and the accurate control of 3D trajectory have been carried out. The application and improvement of MWD and LWD instruments and drilling technology have been carried out. Some breakthroughs have been made in reducing downhole complex situation and safety technology of platform cluster horizontal well, and good scientific and technical practical results, economic and social benefits have been obtained, and the international level of three-dimensional cluster horizontal well technology has been achieved. The purpose of this paper is to summarize the technical experience of three-dimensional bundled horizontal wells, to form a technical template for the application of the technology in this area, and even in other countries and regions, and to apply it to the petroleum drilling industry as a relatively mature drilling technology in China. The research of this subject has realized the first successful application of platform cluster horizontal well in BA oilfield, formed a set of 3D horizontal well trajectory control technology with large horizontal span, and realized the safe drilling of platform bundle horizontal well. Drilling cycle shortened by more than 10%, forming a technical template. The research process of this paper is basically synchronized with the whole BA directional well project. At present, the first phase of the project has been completed and the construction of all 39 wells has been successfully completed, which provides reference materials and technical templates for the development of other projects. This technology will certainly be used in other projects in the region on a large scale. The successful application of 3D cluster horizontal well technology also makes the Chinese directional well brand more resounding in this area and even the whole overseas directional well service market.
