长庆气田属低渗、薄层、地层—岩性圈闭定容气田，气层非均质性严重。针对长庆气田气层特征，从井网方式（包括方向、井距）与气层连通性、相对排气半径、采气速度、单井控制储量、非均衡开采的关系以及经济极限井距等方面研究了气田开发的井网问题；提出了在基础井网上抽稀、分批钻井、逐步调整加密形成最终开发井网的部署方案，该方案适合于长庆气田的地质特征。经测算，气井的经济极限井距为２ｋｍ；高产区采气速度与低产区采气速度之比应在３以下为宜；不同产能井区的相对排气半径差别较大，单井控制的有效排气面积可以相差较大。经过调整、加密的最终井网其井距接近于经济极限井距，可获得较好的单井产能和较高的气藏采收率。
Changqing gas field is a low permeability, thin, stratigraphic - lithologic trapped closed-capacity gas field, serious heterogeneity of gas layers. According to the characteristics of gas reservoirs in Changqing gas field, the relationships between well pattern (including direction and well spacing) and gas-phase connectivity, relative exhaust radius, gas recovery rate, single-well controlled reserves, unbalanced mining and economic limit well spacing The paper studies the well pattern of the gas field development and puts forward a scheme of pumping dilute and batch drilling on the basis of the well pattern and gradually adjusting the encryption to form the final development well patterns. The scheme is suitable for the geological characteristics of Changqing gas field. It is estimated that the gas well has an economic limit well spacing of 2km; the ratio of the gas production rate in high-yielding areas to the gas production rate in low-yielding areas should be less than 3; the relative exhaust radii in different production well areas differ greatly, Effective exhaust area can vary greatly. After adjustment, the well spacing of the encrypted final well pattern is close to the economic limit well spacing, obtaining better single well productivity and higher gas recovery.
