In April 2014, the well was shut down due to the low production gas flow during the perforation and gas test in the Feixianguan Formation of the marine strata of the well.
When it took Party A 8 hours to replace the fracturing wellhead gate, the sixth fracturing team and the fourth gas testing team carried forward the spirit of continuous combat, hard work and dedication, and successfully completed the construction task.
The daily natural gas output is 58000 cubic meters and the oil pressure is maintained at 12.8 MPa.

Finally, the fracturing construction successfully met the design requirements, and effectively communicated with the fracture body 150 meters away! The soldiers in the Central Plains underground awakened the gas dragon who had been sleeping for eight years with the iron army style of being conscientious and daring to fight hard, and presented gifts to the 20th National Congress of the Communist Party of China with practical actions.
The conventional fracturing scheme of “gel forming long fracture” is adopted for the targeted operation of the well, and the simulated fracture length is designed to be 153m.
At the same time, stable industrial gas flow has been achieved.
During the construction, they overcame the water source difficulties and high microbial content, strictly controlled the construction quality, and held the key gate of fluid preparation.
Well Jiulong 1 is a marine pre exploration well deployed in the high part of Block Ma 2, Mababei anticlinal structural belt, Tongnanba block, with the completed drilling depth of 6033m.
Recently, the fracturing construction of Well Jiulong 1, contracted by the downhole special operation company of Zhongyuan Petroleum Engineering Company, has been successfully completed.
After accepting the construction task of Party A, the fracturing team 6 of the fracturing and acidizing project department of the downhole special operation company and the gas testing team 4 of the Puguang project department form a joint team to jointly undertake the construction task.
