Brine volume of natural gas within the well bore calculation


Xiang 11997 on at 8:00 on March 25 1Ol Xiang well production parameters measured out in the brine water pressure sets the amount of pressure the temperature of salt brine temperature and concentration of ancient wells were marked side (MPa) (MPa )()()( ℃) (℃ ) ('Be) (g / L) () in 2 well 8.103812.531.0204022.7303.609412101 Well 5. O5.617.8 production data collected in that post. Two wells were calculated and then four-shaft bottom hole pressure. 2 well in the center tube bottom pressure: P = P, 2 wells in the well hidden + P + P resistance = 81 + plghl-Pm = 30.45 (MPa) in the bottom 2 well casing pressure ring: P, 2 wells Well ring ring = P + P + P hidden resistance = 0.38 + p a PZ2 = 30.28 (Ⅳ 【Pa) 101 shaft center tube bottom pressure: Plot ~ + = P in + P + P b = 5 tiny .0 + Plgh3 survey of a P = 30.51 (MPa) 101 well bottom hole pressure for the casing ring: PIo say ring ring = P + P Gan = 5.6 + pl】 4 million is not 101 wells on the ring-type casing h4 actual length of the h4, but should be the length of the actual fluid-filled. To reduce the error, can the continuity of cavern bottom, select the center tube 101 and the ring tube wells two battalions of the liquid continuous basis. Namely: Pl0l wells = Pl01 well hidden P10l Central + P wells of a well ring = Pl01 Pl foot = 30.51 a ~ g (h3 a tl4) = 30.27 (MPa) where PI is 101 children with the ring center tube wells casing two Kunming Salt Mine Yang Yun Yi (Yunnan tranquility 650,300) to co-open the current bi. Salt Brine rapid development of new technology. Brine connectivity technology in particular has been widely promoted and applied. From the information we learned. Brine production processes connected with low cost, simple to manage,[link widoczny dla zalogowanych], pressure stability, high yield, good quality brine, the advantages of the well less accidents. In recent years a lot of salt brine using this technology have been successful. In terms of my mine. Brine convection process is adopted, three single well pad method of oil production. After the result of natural convection melting through to the production well group. Convection through the production well group practice. Our technology management, from the well structure,[link widoczny dla zalogowanych], operation design, operation and other aspects of the collation of data to explore. Now I have mine set of measures for the technical management of the convection provide peer reference. 2 casing into the mine after the convection well group. Original casing no longer meet the requirements of new technology. So. The original production well casing made major changes. Single well flow to production wells is no longer the center of the tube pulled out all the people well, and improve the production casing height, well set to adapt the needs of the convection. The changed structure of the well casing: surface casing, intermediate casing, production casing. Which, under the port exposed to rock salt production casing seam thickness of 25m - 50m. Running through the year, the pressure difference from the question. The l】 4 = (310 × .210007-5 × .61) = 2514.78 (m) end. Calculate the share of natural gas volume: V-day: S ring × (1 feast of a l) = 0.736 (m3) if want to know when the release of natural gas in the volume of the atmosphere. Can be obtained through the ideal gas equation of state. P1 × V1/T1 = P2 × V2 under the pressure of the gas temperature due to two of little change. Ie =. So there:: P1 × V1/P2 = 5.6 × 0.7364-0.1013 = 40.68 (m3) 3 handling measures and lessons learned brine mining wells. Brine Well always pressure change should be noted. If there is a loss of pressure due to gas generated brine well \In order to reduce the damage caused by this reason, I mine technical staff, to explore a complete set of technical measures to resolve the case of natural gas emissions. First of all. Branch led by the mining companies and organization and implementation. Deep understanding of the technical difficulties and detailed points. Second, the technical staff on-site emissions of pride to the uniform,[link widoczny dla zalogowanych], slow, steady discharge, in order to reduce \Third,[link widoczny dla zalogowanych], the wellhead equipment at the place of direct holding, without a ground back to the brine line. IV. Pay attention to safety, do a good job of natural gas emissions, all aspects of store work. Prevention of wells, ground equipment,[link widoczny dla zalogowanych], construction workers an accident. By calculating the volume of natural gas within the wellbore. Determine the release, storage, transportation of natural gas scale to both protect the shaft and the cavern to resume normal production. For enterprises to achieve better economic and laid a solid foundation.
