Chinese oil network news September 7th, by optimizing all kinds of technology, oil and Gas Engineering Institute of Jilin oilfield exploration deployment and test requirements on gas production test evaluation, total site tracking 8 wells. Among them, Su 2 well received high yield, Nissan gas up to 190 thousand cubic meters.
The gas reservoirs in Jilin oilfield are complex and diverse, with complex conditions such as low pressure and condensate. After years of key research experiments, researchers have formed such technologies as post test gas drainage, reservoir protection, condensate gas reservoir test and gas matching, which are suitable for the Jilin oilfield, and ensure the smooth development of the subsequent development of the evaluation wells.
In order to ensure the development effect of Jilin oilfield preliminary determine the type of Chang 29-3 wells and other properties of condensate gas reservoirs, and provide the basis for the test gas production process selection, adjustment measures; carry out analysis of Chang 29-3 wells mine shafthigh pressurenature sample and experiment, the method of sampling, timing and experiment method to conduct feasibility studies, to determine the layer of dew point pressure 17.67 MPa, for condensate gas reservoirs with oil ring. The determination of gas reservoir types and dew point makes clear the theoretical understanding of production, namely condensate, and provides a theoretical basis for fracturing methods and reservoir protection measures.
Jilin oilfield in Dehui depression, palace and other low, sensitive, no gas, no gas exploration wells more practical, in the analysis of wellbore fluid, with critical liquid discharge process optimization based on the optimization design of gas drainage engineering to carry out the integration of technology, design of perforating, fracturing and formation of gas test integration process pipe column and a tripcolumn to realize all functions of homework, saving gas test materials, and shorten the process cycle.
