【摘要】：近年來，由于人們對油氣資源需求的不斷增大，鉆井勘探領(lǐng)域受到國內(nèi)外越來越多研究人員的重視。隨著研究的不斷深入，鉆井勘探在地質(zhì)勘探領(lǐng)域中占據(jù)著越來越重要的位置，，相關(guān)的鉆井勘探理論，如測斜計算、防碰撞算法、中靶分析算法等，也在不斷的發(fā)展和改進。經(jīng)過多年的努力，鉆井勘探理論研究取得了豐碩的成果。目前，如何將鉆井勘探理論成果應用到實際施工現(xiàn)場成為了一個研究熱點。 本文首先對鉆井過程進行調(diào)研，詳細介紹了鉆井施工過程及鉆井勘探理論相關(guān)術(shù)語，為可視化井眼跟蹤地質(zhì)導向軟件的開發(fā)提供基本的施工信息。然后對鉆井勘探相關(guān)理論進行深入研究，主要研究了三個方面，有：測斜計算、防碰撞算法、中靶分析。在測斜計算算法中，通過對鉆井井眼軌跡模型進行詳細分析和對比，提出了一種新的測斜計算算法—基于非等變圓柱螺線井眼軌跡測斜算法。在防碰撞算法中，利用插值計算算法實現(xiàn)了防碰撞算法中掃描點參數(shù)的確定。在中靶分析算法中，設(shè)計了七種靶類型，基于水平井和定向井中靶分析的差異，分別利用圓形靶和長方體靶作為定向井中靶分析和水平井中靶分析的靶區(qū)。 本文將國家重大科學儀器設(shè)備開發(fā)專項項目的子項目—可視化井眼跟蹤地質(zhì)導向軟件作為本文應用部分，在對鉆井測斜計算、鉆井防碰撞算法、鉆井中靶分析三個方面深入研究分析的同時，關(guān)注實際應用，以Qt程序設(shè)計語言作為開發(fā)工具，實現(xiàn)了可視化井眼跟蹤地質(zhì)導向軟件的開發(fā)。該軟件為地質(zhì)勘探施工人員提供了巨大幫助和指導。
[Abstract]:In recent years, due to the increasing demand for oil and gas resources, more and more researchers at home and abroad pay attention to the drilling exploration field. Drilling exploration plays a more and more important role in the field of geological exploration. Relevant drilling exploration theories, such as slant calculation, anti-collision algorithm, mid-target analysis algorithm, etc., are also developing and improving. Great achievements have been made in the research of drilling exploration theory. At present, how to apply drilling exploration theory to actual construction site has become a research hotspot. In this paper, first of all, the drilling process is investigated, and the relevant terms of drilling construction process and drilling exploration theory are introduced in detail. This paper provides basic construction information for the development of visual borehole tracking geological guidance software. Then, the related theory of drilling exploration is studied in depth, mainly in three aspects: diagonal calculation, anti-collision algorithm, Middle target analysis. In the calculation algorithm of slanting, through the detailed analysis and comparison of borehole trajectory model, a new algorithm of slanting calculation is proposed, which is based on non-equivariant cylindrical helical trajectory. In the anti-collision algorithm, The parameters of scanning point in anti-collision algorithm are determined by interpolation algorithm. In the mid-target analysis algorithm, seven target types are designed, based on the difference of target analysis between horizontal well and directional well. The circular target and cuboid target are used as the target areas for target analysis in directional well and horizontal well, respectively. In this paper, the visual borehole tracking and geological guidance software, which is the subproject of the national major scientific instrument and equipment development project, is taken as the application part of this paper, and the drilling deviation calculation, drilling anti-collision algorithm, While deeply studying and analyzing the three aspects of target analysis in drilling, we pay attention to the practical application and use QT programming language as the development tool. The development of visual borehole tracking geological guidance software is realized, which provides great help and guidance for geological exploration construction personnel.
