This paper is based on practical drilling data of drilled irruptive rock body in western sha segment of huimin depression, rock body subfacies in this phrase and seismic, electric logging features in pyrolysis metamorphic belt are analyzed, so as to summarize a set of practical methods, which identify drilled various subfacies and irruptive rock top and bottom boundary by cuttings log and drill time logging
本文以惠民凹陷西部沙三段已鉆遇侵入巖體的實鉆資料為依據，嘗試性地對沙三段侵入巖體各亞相帶及熱解觸變質帶的地震、電測響應特徵進行研究，總結出一套較為實用的通過巖屑錄井、鉆時錄井手段識別所鉆遇的各亞相帶和進行侵入巖體頂、底界卡定方法，現場應用效果很好。 -
Model lb fishing cup is a practical and effective tool. during drilling operation, it can be used to recover the heavier drilling cuttings or metal chips which are difficult to be lifted out of the borehole by normal drillig fluid circulation
它是用來撈取鉆井過程中正常的泥漿循環無法帶出井眼的較重鉆屑或金屬碎屑的一種實用有效的隨鉆工具。 -
Wld is a high - temperature anti - sloughing agent, which contains si and organic compound ion. by applying it with polymer drilling fluid in the high - temperature deep well and the well section of heaving mud shale, it can improve the stability of drilling fluid dramatically. and at the same time, it can deactivate the drill cuttings and the wall surface active point to greatly improve the property of rejection and anti - sloughing of the drilling fluid through the physical - chemical action occurring between the special group of molecule vs. drill cuttings and the wall surface
Wld高溫防塌劑是一種含有si元素和有機復合離子的抗高溫防塌劑，在高溫深井及易垮塌的泥頁巖井段配合聚合物鉆井液使用，不僅可以顯著改善鉆井液的穩定性，而且可以利用分子中的特種基團與鉆屑和井壁表面發生物理-化學作用，使鉆屑和井壁表面活性點鈍化而顯著提高鉆井液的抑制防塌能力。 -
Field using indicates that the polymer drilling fluid is suitable for the large size hole because of its remarkable cuttings removal ability ; and polysulfide drilling fluid shows its strong inhibition, anti - sloughing and good cuttings transportation ; while for polysulfide drilling fluid mixed with oil, it has better cuttings removal, suspension and lubricity, which are desirable for horizontal drilling
現場應用結果表明，聚合物鉆井液體系解決了大井眼攜巖問題；聚磺鉆井液體系抑制能力、防塌能力、攜巖能力強；聚磺混油鉆井液體系的攜帶、懸浮巖屑能力及潤滑性更好。 -
