Abstract: With oil and gas exploration and development unfolded continually and extensively, there are more and more wells of complicated layers, wells of complicated structure and horizontal wells with super-large displacement. Therefore, the market demand for high-performance drilling liquid technology is on the rise. Comparing with the international advanced technology, Greatwall Drilling Co., Ltd. highlighted the intellectual property “family-technology-product” principle and formulated a three-level IP protection wall strategy on the basis of the “protection type, confrontation type and stockpiling type” IP distribution. Based on a “technology-patent-standard” integration, the company established, step by step, the patent groups of the full industrial chain of GWHP-FLEX? technological family, accompanied with registration of software authorship and registration of trade marks, to fully protect the relative patent technology of amine prohibitor and its amine drilling fluid system as well as its extended patent technology. The company successfully eliminated the foreign IP barriers and effectively helped the technology converted to create economic results on the domestic and overseas markets, such as in Chad and Niger as well as Xuyong shallow-layer shale gas in Sichuan. Therefore, the company has brought the whole drilling fluid industrial chain under high-quality development.
