连续油管压裂技术资料（Technical data of coiled tubing fracturing）

连续油管压裂技术资料（Technical data of coiled tubing fracturing） The pressure drop of nozzle can be obtained by square fitting of the test result Because has the higher applicability and operability, is expected to be between fan and displacement, the commonly used Xia 6 The MM nozzle is fitted (Figure 1) to be obtained Popularization and application. To the following relation: Foundation project: PetroChina Co Ltds leading project Pilot test of low permeability sandstone gas reservoir development in Xujiahe formation of Sichuan Basin Part of the research results. Biography: Wang Tengfei, born in 1981, engineer, Ph. D.; 2007. Graduated from the school of petroleum engineering of Southwest Petroleum University; mainly engaged in the technology of increasing production and transformation of low permeability reservoirs Work. Address: (065007) mailbox 44, Wan Zhuang, Hebei, Langfang. Tel: (010) 692131821347236689. E - Mail:wangpfei69 P ? 2. Natural gas industry, January 2010 chart Fig. 2 fitting curve of pressure drop and displacement of 1 nozzle Y = 217.5 X29.85 X1.535 (1) After knowing the throttle friction of nozzle, it is divided into tubing and annulus construction Do not calculate the total friction as follows: Xia 44.45 Mm coiled tubing, with a total length of 4000 M; cannula for Xia 139.7 Mm; 6 Xia 6 Mm nozzle, the friction coefficient of fracturing fluid is 0.3. 1) tubing injection. The frictional resistance of tubing is injected by simulation (see Figure 2): if an oil pipe is used to fracture it, even if it takes 1.5 M3 / min displacement, total friction will be as high as 66 M Pa, assuming the treatment layer is deep For 3000 M, the formation fracture pressure gradient is 0.019 M Pa / m, then To make formation rupture, the wellhead pressure must meet the following conditions: P wellhead + P liquid column P friction PF (2) Type: P wellhead is the wellhead pressure; P liquid column is liquid column pressure; P friction is Guan Zhu Frictional pressure; pF is formation fr
