Preparation of compound ion profile adjustment agent and its improvement 復(fù)合離子調(diào)剖劑配制方法及改進(jìn)
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(jī)復(fù)合離子的抗高溫防塌劑,在高溫深井及易垮塌的泥頁(yè)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(wěn)定性,而且可以利用分子中的特種基團(tuán)與鉆屑和井壁表面發(fā)生物理-化學(xué)作用,使鉆屑和井壁表面活性點(diǎn)鈍化而顯著提高鉆井液的抑制防塌能力。
