最近 ,Texaco公司在Bryant-G -Devonian油田的开发中获得显著成效 ,该油田位于Permi an盆地。以前 ,该油田日产天然气 2〔10 6 ft3,日产凝析油 10 0bbl,通过改进油藏描述和水平钻井技术 ,目前天然气产量提高至 6 0〔10 6 ft3/d ,凝析油 2 6 0 0bbl/d ,比预期的可采储量高 30 0 %。另外 ,增产方案的实施 ,使Texaco公司的天然气处理厂生产的凝析油产量增加。方案实施期间 ,大约钻成50个水平侧支井段 ,包括现有井的侧钻和浅油砂层的新井 ,有些是单分支井 ,有些是多分支井。在Permian盆地 ,Texaco公司所钻的井是一组最深的水平井 (>10 0 0 0ft) ,其生产曲线相对陡峭 ,且常常折曲
Recently, Texaco has achieved significant results in the development of the Bryant-G-Devonian field, which is located in the Permi an basin. In the past, the natural gas production in this oil field was 2 10 6 ft 3 and the daily condensate oil was 10 0 bbl. By improving the reservoir description and horizontal drilling technology, the output of natural gas has been increased to 60% at present, and the condensate at 260 bbl / d, 30% more than the expected recoverable reserves. In addition, the implementation of the stimulation program has increased the production of condensate from Texaco’s natural gas processing plant. During the program, about 50 horizontal lateral support sections were drilled, including new wells in the sidetraits and shallow sands of the existing wells, some of which are single-well and some of which are multilateral wells. In the Permian Basin, the wells drilled by Texaco are the deepest horizontal wells (> 10 0 ft) with relatively steep production curves and often buckling
