针对中原油田开发现状，研制了一种新型的有机—无机复合堵剂（ＪＴＤ），并对其性能进行了全面的评价。结果表明，ＪＴＤ堵剂成胶性能好，封堵强度高，耐冲刷性能好，尤其适应于封堵高渗透、大孔道地层，且现场施工简便，施工用量少，成本低。该堵剂在中原油田、南阳油田和新疆乌尔禾油田推广应用１００多井次，施工成功率１００％，有效率大于９０％，取得了较好的社会经济效益
Aiming at the status quo of Zhongyuan oilfield development, a new type of organic-inorganic composite plugging agent (JTD) was developed, and its performance was evaluated comprehensively. The results show that the JTD plugging agent has good gelling performance, high sealing strength and good erosion resistance, especially suitable for sealing high permeability and large pore strata. The construction of the JTD plugging agent is simple and convenient, with less construction cost and low cost. The plugging agent has been widely used in more than 100 wells in Zhongyuan Oilfield, Nanyang Oilfield and Wuerhe Oilfield in Xinjiang. The success rate of construction is 100%, and the effective rate is over 90%, which has achieved good social and economic benefits
