Exploration company: another unimpeded flow rate of more than one million cubic meters of gas wells

On September 3, a gas well in Jingbian area of Exploration Company's Gas Production Second Plant gained a new high in gas test and production, with an unimpeded flow rate of 1,289,400 cubic meters per day, which is the third gas well with more than one million cubic meters harvested by the plant this year, and also the 10th one million cubic meters or more since the establishment of the gas production second plant, demonstrating a good prospect of increasing the scale of storage and building production with benefits for the Ma Five Layer.

The well is a development well in the northern part of the 15 billion cubic meters production capacity construction project of the exploration company, belonging to the Yan 969 production well area of the Second Gas Production Plant, and the test gas layer is the lower ancient Majiagou, the discovery of this well can effectively slow down the decreasing rate of the production capacity of the Yan 969 well area, laying the foundation for long-term stable production.



In the process of development, the technicians, by analyzing the geological analysis of the Jingbian area development, applying the residual thickness method, impression method, logging fine interpretation and other methods to effectively carry out ancient geomorphology restoration research, predicting the favorable phase zone of the MaWu1+2 reservoir, and selecting the potential residual hill-ancient trench transition zone, this section of dolomite is subjected to the filtering and dissolving action, with good physical conditions and a high degree of natural gas filling, which provides a solid geologic basis for the single-well yield of the gas test well. The dolomite in this section has good physical conditions through leaching and erosion.



In the construction of production capacity in the northern part of Yan'an gas field, Gas Production Plant No. 2 attaches great importance to the drilling and testing of gas wells, and strengthens the optimization of geo-engineering design and on-site control, so as to ensure that the construction of wells improves the quality, speed, and efficiency of the operation. The plant adheres to the integration of geological and physical exploration, establishes seismic response modes for different reservoirs, selects target zones, and improves the quality of deployment; at the same time, the plant strengthens the selection of drilling and completion technology programs such as well body structure and bit selection, strengthens on-site organization and management, and relies on wells to ensure that drilling and testing are fully accelerated; in addition, it strictly implements the mechanism of cadre packages for wells to solidify the responsibility of the work, strengthens supervision and inspection at the work site, and promptly disposes of problems and hidden dangers to ensure that wells are built in time. In addition, the company strictly implements the mechanism of cadre well chartering, consolidates work responsibilities, strengthens supervision and inspection of the operation site, disposes of problems and hidden dangers in a timely manner, and ensures safe and efficient progress of well construction.
