Proper selection of the drill bit can improve drilling efficiency, guiding ability and wellbore stability. As oil and gas exploration and development goes deep into the stratum, moving towards new blocks including the surrounding areas of the original structure, and moving toward new technologies, drilling users urgently need to develop drill bits that adapt to the new technology of horizontal wells and underbalanced wells. In recent years, the company has closely relied on on-site service and technological innovation capabilities, and has focused on strengthening the development of small-sized drill bits of 12 inches or more and 6 1/2 inches or less. The size series and variety series of drill bits have been rapidly improved, thus becoming the leader. With the new advantages of Other roller cone drill manufacturers in China, the company's product market advantage has expanded to the entire well section.
All along, Jiang Diamond Co., Ltd. relies on its technical strength to maintain a high market share in the roller bit market with a drilling depth of more than 3,000 meters in China, targeting the middle and deep sections. Enterprises have invested relatively little in the use of large-scale drill bits for shallow formations, basically in a situation where the product series is relatively single and there is not much competitive advantage. To develop and expand the "big" bit market and expand the bit market, it is bound to be limited by the existing large-scale drill bit manufacturing capacity, and suppliers that can provide large bit blanks in China are still to be developed. In recent years, the company has developed a “new springboard†for the development of the market as a drill bit. Under the condition that the original market of Jiang Drills is basically saturated, the company has vigorously developed the big drill market and tried every means to solve the difficulties encountered. . There is no supplier that can provide large drill bits in China. The company will not hesitate to invest and gradually develop domestic suppliers. Finally, it basically solves the problem of supply sources of large bit blanks. If the existing large drill bit production capacity is insufficient, it will step up purchasing equipment and optimize. Deploying human resources and other aspects, expanding production capacity; the performance of large drill bits is still not up to standard, and adopting targeted development methods, keeping a close eye on the market, and giving full play to the advantages of independent innovation, gradually forming a variety of products, multiple grades , serialization and specialization, the competitiveness of the enterprise's large drill bit has been rapidly improved, and the speed of the shallow stratum has been promoted, and the market has also been expanded.
In November last year, the company carried out the development and test tracking of large drill bits of 17 1/2 and 12 1/2 series according to the situation of the Sichuan-Yunnan region and according to the needs of drilling users. The 17 1/2 drill machine developed. The drilling speed is 26% higher than that of other manufacturers using the same block. The developed 12 1/2 drill bit has the characteristics of stable drilling, fast drilling speed and long footage during the drilling process. It has strong competition. Force, the market share of Jiang Drill's large-sized roller bit market in the northeastern Sichuan block increased from less than 10% to over 40%.
In deep well drilling operations, many wellbore drillings have not completely passed through the supporting technologies such as drill bits and power drills, resulting in slow drilling speeds in deep well drilling operations, increased drilling costs, and deep wellbore drilling. Torque, displacement, and drilling pressure are all greatly limited. The small-sized drill bits and power drills used in deep small boreholes are the key to improving the drilling speed of small-diameter wellbores.
Jiang Diamond Co., Ltd. wants to break the price reduction method adopted by some domestic drill suppliers or the non-standard sales behavior under the condition of fierce competition in the drill bit market and the price increase of raw and auxiliary materials, so as to maximize the small size of the deep hard formation. The bit market is beneficial to brand building and certain profit maintenance. In the development of small-sized drill bits, in recent years, the company has further strengthened the resource cooperation with the joint research institutes of Karamay and Jianghan in Xinjiang on the basis of the original, focusing on the equally complex strata of the northeastern Sichuan, and carried out pilot work. Collecting enterprises and using the superior resources of both parties, tracking the statistical data of drill bits, collecting typical drill bits, establishing an analysis database, and forming a standardized drill selection series and using parameter schemes adapted to different regions or strata, in response to the geological conditions and requirements faced. The construction of small-sized drill bits in complex formations has made useful explorations and achieved phased results.
Since last year, Liaohe Oilfield is the largest oilfield with 6-inch three-toothed drill bits in China. It is mostly used in directional wells or horizontal wells with deep layers. Here, the trial results of several other domestic drill manufacturers are not satisfactory. In this regard, Jiang Diamond Co., Ltd. designed the main line of “improving the service life, footage and safety reliability of the drill bitâ€. The targeted development of 6 drills of 6 models including 6HJ517G and 6MD517 has been recognized by users and obtained. The user's successive orders. In addition, with a sound product line and a good reputation in the domestic market, the company also succeeded in winning a block in the northeastern Sichuan region involving 18 7/8, 13 1/2, 7 3/8, 5 1/2, etc. The series of product contracts, in which the 18 7/8 drill bit developed and produced, fills the blank of the largest size in the country.
At present, the company's production and sales of large and small drill bits have accounted for a considerable proportion of the company's total production and sales of drill bits. The construction of large and small drills has boosted the competitiveness of the company's products and the overall production and sales. In 2007, the company's roller root drills developed steadily at home and abroad, and opened up new markets such as Colombia, Congo, and Greece.
Jiang Diamond shares: product advantages to "two heads" development
Recently, a key exploration well in the Tuha Oilfield has selected diamond drill bits and roller cone drills from Jianghan Oilfield Co., Ltd. from the shallow strata to the deep strata. Similar to the well, many wells in the field are currently completed using this bit combination. It is reported that the share of Jiang Drilling roller bit in the Tuha oilfield market has achieved more than 90%.
