马井气田是于 1 997年底发现的新气田 ,至今已完钻 1 5口井 ,1 2口井获工业气流。该气田试采过程中马蓬 3井、马蓬 7井产水、川马 60 1井、马蓬 2井产少量凝析油 ,川马 60 2井产少量水及凝析油。根据该气田一年来的试采特征及该地区储层低孔、低渗透及地层水区域分布的特点 ,提出了该气田勘探过程中的布井井位及钻井过程中的储层保护技术、气层改造加砂压裂技术以及开发过程中的防砂堵砂技术、泡沫排水技术。这些开发技术的实施 ,在一定程度上提高了气井的生产能力 ,增大了气田的产量。
The new gas field discovered at the end of 1997 in the Majing gas field has so far completed 15 wells and 12 industrial wells. During the trial production of the gas field, Mapeng3 well and Ma Peng7 well produced water, and a small amount of condensate oil was produced in the well of Chuanma 60 1 and Mapeng 2, and a small amount of water and condensate oil were produced in the well of Chuanma 60 2. According to the characteristic of trial production in the gas field in one year and the distribution of low porosity and low permeability reservoirs in the area and the distribution of formation water, reservoir well protection technology and reservoir protection technology during drilling are proposed Sandstone fracturing technology to improve the sandstone and sand technology in the development process, foam drainage technology. The implementation of these development technologies has increased the production capacity of gas wells to a certain extent and increased the output of gas fields.
