川中石油资源丰富,经过30多年的工作,本区生储油有利相带早已查明,但是选点的问题尚未解决。地震找裂缝的技术尚未过关,致使中、高产井的成功率很低。平均日产3t以上的油井不到总探井数的十分之一。 1992年5月川中找油会议上确定要加强科学试验,在川中文津、金华两个试验区的两口干井一文4井和金54井附近进行地震攻关试验,找出裂缝发育带。然后对准裂缝发育带进行侧钻和钻水平井的钻
After more than 30 years of work, the oil and gas facies belt in the region has long been identified, but the issue of the election point has not yet been solved. Seismic technology to find the cracks have not yet passed, resulting in low success rate of wells in the high-yielding. The average number of wells over 3t Nissan less than one-tenth of the total number of wells. In May 1992, at the meeting for oil exploration in Central Sichuan, it was decided to intensify scientific experiments to carry out earthquake research tests in two dry-well No. 1-4 wells and Jin-54 wells in the two pilot areas of Sichuan, Wenjin and Jinhua in order to find fracture development zones. Then align the fracture development zone for sidetracking and horizontal drilling
