摘要根據鉆井篩動力學的基本原理，分析了鉆井液中固相顆粒在非淹沒狀態下相對于振動篩面作后滑、拋擲、靜止和前滑4種運動狀態的動力學條件。A deformational particle with oil - soluable property is used as a bridge plug to build a shielding layer in the oil - gas reservior channel, to prevent the pollution caused by drilling mud entering the reservior due to the pressure difference, and so to protect the oil - gas reservior
摘要用一種具有油溶性質的可變形粒子做橋塞物，在油氣儲層通道中建立橋堵屏蔽層，防止由於壓差造成鉆井泥漿進入儲層而形成污染，從而起到保護油氣儲層的作用。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。The synthetic analysis holds that the conveyance speed of solid phased particles of well drilling liquid moving on the level motioned elliptical linear sieve is again higher than that of circular sieve
綜合分析認為，鉆井液固相顆粒在平動橢圓篩上的運移速度高於直線篩，在直線篩上的運移速度又高於圓型篩。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。On the basis of considering the influences upon the conveyance motion of solid phased particles affected by parameters of motive path of sieve chest, inclination of sieve surface, azimuth of vibration, throwing index and adhesive resistance of well drilling liquid etc., the kinetics equations of conveyance speed and displacement of solid phased particles were established
在考慮篩箱運動軌跡、篩面傾角、振動方向角、拋擲指數和鉆井液粘附阻力等參數對固相顆粒運移影響的基礎上，建立了固相顆粒運移速度和位移的動力學方程。To achieve the objective of protecting reservoir during drilling, the common means is to add proper graded temporary plugging materials, coupled with colloid filling particles in upper drilling fluid based on the average radius of pore throat in reservoir, which converts upper drilling fluid to reservoir protection fluid
摘要在鉆井過程中，為達到保護油層的目的，通常根據油層的平均孔喉半徑，在上部鉆井液中加人合適粒徑的暫堵劑，再配合膠體填充粒子將其改造為對油層具有保護作用的鉆井液。Bullet - shot drill
