大粒金剛石鉆頭Based on the ground outcrops and drilling core samples, and two - dimensional seismic data in this paper, through a comprehensive evaluation and research of the reservoir characteristics, the authors clarifies that the dolomite of the upper sinian dengying formation and the grain limestone of the lower silurian shiniulan formation are main reservoir rocks in the research area, and the sedimentary facies, karstification, and the number of cracks are the main controlling factors of the reservoir quality
以地表露頭、鉆井資料及二維地震資料為基礎，通過儲層特徵綜合評價研究，認為上震旦統燈影組白雲巖、下志留統石牛欄組顆粒灰巖為區內的主要儲集巖，沉積相、巖溶作用及裂縫發育程度為儲層發育的主控因素。To ensure the charging pump working reliably, the following measures should be adopted : ( 1 ) adopting modified circular casing to reduce the radial force of the impeller and decrease the seal clearance ; ( 2 ) using radical ribs on impeller and helical sealing on shaft to realize minor pressure differential ; ( 3 ) using back pressure stuffing box to ensure sealing under small packing force ; ( 4 ) adopting self - lubricant flexible graphite stuffing for absorption of solids entering in the graphite in case of leaking
為確保灌注泵可靠工作，提出改進措施： （ 1 ）採用改型環形泵體降低葉輪的徑向力，減小軸封間隙，抑制泄漏； （ 2 ）採用背葉片降低葉片根部壓頭，獲得微壓，使軸封兩端承受較小壓差； （ 3 ）採用螺旋密封降低軸封兩端壓差，在保持微壓的同時避免出現負壓，密封效果更好； （ 4 ）採用反壓式填料密封結構，在很小的壓緊力下，即可保證密封； （ 5 ）採用具有潤滑功效的柔性石墨填料，即使發生軸封泄漏，進入石墨內部的固相顆粒也將隨著石墨的消耗而被鉆井液吸收。Fabrications and cutting tests of ultrafine grain diamond coated drills
