Realization of water reinjection in gas field of South Sichuan gas field 100%

  China Petroleum Network News "through a number of gas field water reinjection treatment measures, gas mine realized gas field water safety injection, and achieved remarkable results."." In September 8th, He Jiyang, deputy chief engineer of the South gas field company of Southwest Oil and gas field, said.

  In recent years, Shunan implement the national "building a resource-saving and environment-friendly society" policy, for more than 80%, more than 60% gas field gas production of gas field water, grasp the gas field water reinjection well management, realize gas water reinjection 100%.

  Plan ahead and be prepared for it. Passive ideas change the original "gas reinjection wells, difficult to choose" into "active management mode to prepare in advance and steady replacement", since 2010 to carry out the reinjection well well selection demonstration research project 12, selected reserve reinjection well to more than 30, which has been implemented or are being implemented for 15, Gaoshiti shale gas, and other key block gas field water treatment set aside sufficient margin, to ensure that the field of green production.

  Take measures to maintain a good state of reinjection well. Gas injection ability of rapid decline in wells, to carry out dynamic pressure drop testing; the injection space, wellbore and reservoir near the pollution situation analysis and research are carried out, and the preferred implementation of acidification, or hydraulic radial drilling hole when plugging measures; carry out regular annulus operation on the part of the focus of injecting nitrogen reinjection well, effective control of casing the annulus level up, to protect the upper casing and tubing; actively carry out overhaul and removal operations. Since 2011, a total of 34 wells have been re injected and 20 wells have been removed to ensure the well condition of the reinjection well.

  Strengthen monitoring and strictly control environmental risks. Gas on water surface surrounding water reinjection well periodic sampling and analysis, master the changes of key parameters of surrounding surface water pH, Cl - chlorine content, if found timely control measures anomalies, and in some key reinjection well surrounding the construction of pollution monitoring wells of water reinjection well monitor, ensure zero pollution.
