水溶性暂堵剂
针对海上油气田和高含水油井措施作业的要求和特点，设计并研制出zd系列水溶性暂堵剂。zd水溶性暂堵剂主要成份为微溶于水的化合物和无机盐类，并用特殊的工艺进行了表面处理，在常温下不溶于水或微溶于水，在地层温度下，可通过架桥、充填和变形等作用，在地层表而形成一条低渗透性的暂堵带，从而阻止入井流体的浸入和伤害，作业完成后，zd可被水逐渐溶解而自行解堵。
  水溶性暂堵剂为黄色颗粒物，水溶解率≥95％，暂堵率：≥95％，渗透率恢复值≥85%，适应温度范围40～120℃。
  主要适用于海上油气田和陆上高含水油井和水井的修井、压井、冲砂等作业的入井流体的暂堵，减少入井流体的浸入，保持油气层，也可用作高含水油水井选择性酸化的暂堵剂和转向剂。作为修井压井的暂堵剂使用时,用清水将zd配成3～5％的水基液，直接泵入地层即可。作为修井压井液的暂堵剂使用时,也可直接加入到压井液中使用，每米地层用量一般为2～5m3。
water soluble temporary plugging agent
for the offshore oil and gas fields with high water cut oil well measures operating characteristics and requirements, design and manufacture of a series of zd water soluble temporary plugging agent. zd water soluble temporary plugging agent is the main ingredients of water-soluble compounds and inorganic salts, and the special technology of surface treatment, under the normal temperature water insoluble or slightly soluble in water, the formation temperature, through the bridge, filling and deformation and so on, in the formation of a table low permeability plugging zone, thereby preventing the fluid immersion and injury, after the operation is completed, zd will be gradually dissolved in water self plugging.
water soluble temporary plugging agent for the yellow particles, water dissolution rate greater than 95%, plugging rate: greater than or equal to 95%, the permeability recovery value is more than 85%, to adapt to the temperature range of 40 ~ 120 deg c.
mainly used in offshore oil and gas fields and the high water cut oil well and water well workover, well, the sand washing operation of fluid into the well plugging, reducing the immersion fluid into the well, keep the oil and gas, but also can be used as high water cut oil well selective acidification and temporary plugging agent to agent. as the pressure well workover plugging agent used, the use of water base fluid zd with 3 ~ 5%, the formation can be pumped directly into. as the well killing fluid workover plugging agent, also can be directly added to the use of well killing fluid in the formation, the amount of per meter is generally 2 ~ 5m3.
