【摘要】：定向取心技術(shù),是一種特殊取心技術(shù),它能夠確定巖心所處地層裂縫的傾角、傾向等要素,它主要由定向取心工具、無磁鉆鋌、電子多點(diǎn)測量儀和巖心復(fù)位儀等組成。定向取心技術(shù)對地質(zhì)構(gòu)造的研究,尤其是裂縫性油氣田裂縫分布規(guī)律的研究,以及制定合理開發(fā)方案具有非常重要意義。本次研究首先要深入調(diào)研國內(nèi)外技術(shù),并針對現(xiàn)有技術(shù)的弊端進(jìn)行分析,結(jié)合實(shí)際情況,開展工具方面的研究。通過地面試驗(yàn)和現(xiàn)場應(yīng)用,改進(jìn)完善定向取心技術(shù),使之具備現(xiàn)場應(yīng)用的能力。工具改進(jìn)的技術(shù)關(guān)鍵主要是定向取心工具和電子多點(diǎn)測斜儀的嚙合、定向取心工具配件的改進(jìn)和巖心地面復(fù)位解釋技術(shù)。定向取心工具配件要達(dá)到巖心出地面能夠復(fù)位的要求,定向取心鉆頭則是研究出適應(yīng)不同地層鉆頭。巖心地面復(fù)位解釋技術(shù)也是定向取心技術(shù)研究的關(guān)鍵�！岸ㄏ蛉⌒募夹g(shù)研究”是在常規(guī)自鎖式取心工具基礎(chǔ)上,設(shè)計(jì)了DX101-A型定向取心工具,獨(dú)創(chuàng)性地研制了三刻刀巖心爪總成,研究了電子多點(diǎn)測量儀與定向取心工具的嚙合,研究并制成了巖心地面復(fù)位儀及巖心復(fù)位解釋技術(shù)等一整套具有自主知識產(chǎn)權(quán)的DX101-A型定向取心工具與技術(shù),制定了科學(xué)實(shí)用的操作規(guī)程和現(xiàn)場施工措施。
[Abstract]:Directional coring is a special coring technique, which can determine the inclination and inclination of the formation fracture in which the core is located. It mainly consists of directional coring tool, non-magnetic drill collar, electronic multi-point measuring instrument and core reset instrument. Directional coring technique is of great significance to the study of geological structure, especially to the distribution of fracture in fractured oil and gas fields, and to the formulation of reasonable development plan. In this study, firstly, the domestic and foreign technologies should be investigated deeply, and the disadvantages of the existing technologies should be analyzed, and the tools should be studied in combination with the actual situation. Through ground test and field application, improve the directional coring technology and make it have the ability of field application. The key technology of tool improvement is the meshing of directional coring tool and electronic multi-point inclinometer, the improvement of directional coring tool fittings and the interpretation technology of core ground reset. The directional coring tool fittings should meet the requirement that the core out of the ground can be reset, and the directional coring bit is a bit adapted to different strata. The core ground reset interpretation technique is also the key to the research of directional coring technology. On the basis of the conventional self-locking coring tool, DX101-A type directional coring tool was designed, and the three-notch cutter core claw assembly was developed, and the meshing between the electronic multi-point measuring instrument and the directional coring tool was studied. A set of DX101-A directional coring tools and techniques with independent intellectual property rights, such as core ground reset instrument and core reset interpretation technology, have been developed, and scientific and practical operation rules and site construction measures have been established.
